To the north lies the urban street, in the south a garden within nature. You find conditions as in Tucholsky's 'The Ideal'. To create a semi-public space along the façade, the ground floor moves back slightly. Each entrance is flanked by a finely tiled bench, next to these lie entrance halls, which connect the house with the happenings on the street. The two-side oriented apartments have a continuous window strip towards the urban side, a small balcony enables a connection to the street. The transition from the private to the community areas is finely graded and invites the inhabitant to get in contact with surrounding neighbours.

On the side of the garden, a pergola creates balconies and loggias for all apartments. The house offers a variety from 2 to 5 ½ room apartments, distributed in a balanced mixture over all floors and offering a wide range of different living needs in all housing sizes. The residents can use the floor plan flexibly, small spaces are arranged around a neutral space as a distributor, which can be both a kitchen and living room. In the apartments of 2 ½ rooms or more, the user can decide freely about having a bedroom to the street or towards the garden. Some large apartments can be divided. Due to the flexibility of the ground plans, many alternative housing forms are possible under one roof, such as housing communities, living/working or living together with multiple generations.

The area between Vogelhüttendeich, Rotenhäuserstraße, Jaffe-David-Kanal and Aßmannkanal has special qualities: it is a landscape in the city. Wilhelmsburg, the Elbe island, originally sparsely populated with its hydraulic engineering can still be experienced here. The canals and many allotments give the area a scenic atmosphere. The pier with its beer garden at Vogelhüttendeich is a place in front of the city but not yet in the countryside. To the west lies the Reiherstieg district, the epitome of a dense, culturally mixed neighbourhood. Here the blocks stand sharply defined as bodies in the landscape, forming a closed space of intensive urban life. In the commercial area south of the planning area, garden elements of a suburban idyll can be found. This temporal, spatial and typological fusion of the landscape with urban and industrial fragments is fundamental to the design.

In Wilhelmsburg, landscape and city meet like living and working. Different typologies stand side by side without constraint, they use and reinforce the qualities of the area, individually or in context. The encounter of different building types with diverse open spaces creates a multitude of independent subspaces. We create urban density through architectural typology. Within a plot, the individual buildings are coherent and create urban space in their specific design.

After converting the 1950's department store into a modern residential and commercial building the only remaining retail spaces were located on the ground floor. The first floor is home to a public recreational room where children whose parents are shopping can be cared for by senior citizens; this space can also be reconfigured to form an office or a surgery. The target groups for the two residential floors are elderly and handicapped people who live in the city and wish to enjoy the advantages of unassisted living.
In the second and third floors there are eight apartments in all, which can be used individually or as a residential cooperative. In order to retain the openness of the former department store, the floor plans are divided only by the addition of core sanitary modules and moveable wall elements. Each apartment has a fully-glazed inner courtyard. The composite thermal insulation system, necessary to keep energy levels low, includes a newly developed light-plaster, which responds to sunlight with the aid of inset glass beads.

date: September 2006

The building of the New National Library marks the western edge of Letenská plain. Even though building mass is added to the area, the wide and open terrain is preserved as a multifunctional urban space. Corresponding to the monumental dimensions of the urban context, the New National Library rests as a simplistic volume on the extended gravel surface of Letenská plain. Oriented parallel to the open area, the building has a square footprint of 97,20m² based on an 8,10 m square grid. To the north, an open plaza provides the main entrance for pedestrians. To the east, the library café, which also serves as an entrance, features a terrace looking onto the infinite gravel surface of Letenská plain.
The New National Library is a hybrid typology between utilitarian functionality and public grandeur.
60% of the floor area is solely used as storage space, only 20% of the floor area is open to the public. The presence of 10 million books creates a monumentality by sheer number, similar to baroque libraries, where visitors and employees are completely surrounded by books. With generic typologies such as supermarkets as a model the scheme juxtaposes the programmatic necessities of separating magazine and public spaces with the baroque approach of universal presence. The enormous size and complexity of a National Library reflects into simplistic spatial matrix.
In plan the 97,20 m deep open space is structured by supportive cylinders and voids in the floor. The voids connect spatially to the lower floors, which are mainly used as magazine spaces. The cylinders also provide controlled natural light through circular patios. Four cores contain vertical circulation, fire escapes, public and freight elevators with car capacity. Upper floors have 6,75 m clearance, lower floors 2,33 m. The neutrality of the system allows for a wide array of possible layouts. Essentially the ground floor contains public services, the first floor reading rooms, the second floor administration and public services. Restaurant and auditorium are also on the second floor.
Each upper floor is accompanied by a secondary lower floor (inverted mezzanine) that provides storage space for the public.

Library is a place of permanence and continuity. It is rooted in Roman remains. Its geometry is based on the universal orthogonal grid of Roman colonial planning. Yet it is a place of change, openness and progress. As a laboratory of knowledge it nurtures scholarship and community.
Here time is no longer linear but becomes simultaneous. Library melts time into a single presence. There is no antagonism of old and new, no ideological compulsion to destroy and overcome. Whether we rest on the shoulders of giants or whether giants stand in our way, the future will know. Library pays tribute to the rich urban fabric of Ljubljana and complements Plečnik's city with humility. It balances between civic grandeur and modesty. To be the New National Library and yet one among many buildings Library is just slightly detached from the city block, an almost stand-alone monument. Almost. Its distribution of building mass emphasizes Zoisova Street as an "University Boulevard" and adapts in scale towards French Revolution Square. Both entrances are marked with recesses and grand stairs. The gap between the city block and Library opens a pedestrian path to cross the courtyard. Access of vehicles for loading, the handicapped, and restricted parking is also permitted here.
Library expands the limits of typologies, it is an open plan building yet contains six distinguished public rooms. Free access shelves and restricted archive areas blend into a continuous space. Physically they are separated by glass walls. Horizontally the public rooms have no limits, the rooms are defined by their voids and their natural light.
A structural system of waffle slabs supported on cores and cross-shaped columns allows large spans and a minimum of piled foundations. The impact on the archeological remains is minimized, the flexibility of the library space is maximized. Library is an open building, the entrance level is a 24h zone. Five reading rooms and the multifunctional hall are spread across the floors. They create zones of distinct character, each with individual spatial qualities. The user can retire to his place of choice. In the special collection he will be among Roman ruins, in the grand reading room underneath the sky. The multipurpose hall is situated on Level 0 and can be used independently from the library.
Library is a place of presence and identity. It is a physical space, it has weight but is still floating. It defines space but stimulates interpretation. Library is multi-folded space.

The street is a field of action, a place of social mixing.

St. Pauli formed by a variety of actors, a diverse cast of characters all of whom meet on the street. The hotel stands on Spielbudenplatz, a colourful hybrid which becomes a street unto itself. It has two ground floors - one at ground level and one on the city balcony - both with countless doors. These two floors—like the street they embrace—are dedicated to characters of St. Pauli, offering them new places for encounters, for meeting, and to linger.

Following the example of the 1920s Haus Vaterland in Berlin, Baufeld 1 is an implosion of urban life that welcomes and delights residents of Hamburg and tourists alike. Various units gathered under a large shell form a series of public spaces ripe for interaction. The city balcony is a distinct throughway connected with the street by stairs at both ends: it is a street and a square in the air.

NEUBAU - on Königsberger Straße and Aleppoer Weg

Germany is an immigration country, in the metropolitan regions there is a housing shortage. By 2026 this shortage will amount to around four million affordable dwellings. In a large model NEUBAU shows four speculative self-build cities which represent a further development of the project Grundbau und Siedler that was implemented at the IBA in Hamburg. A comparison to the major reconstruction work after 1945 reveals similarities and differences over a period of ten years. We call the urban districts "city of assembly". They are co-productions; between the poles of self-determination and planning a wide variety of spaces is developed for community, production, trade, and private use. 50% of the residents have a migration background, these are districts for everyone.

BeL (*2000), Anne-Julchen Bernhardt (*1971) and Jörg Leeser (*1967): On Walter Pichler's Sketch for the Underground City, 1960-64, Model, 2019, metal, concrete, plaster, paint, foam, wood, pastel calk, wood glue, paper, coal, styrofoam, plastic, play dough, sandpaper and plasticine.

The selected drawing – a light-hearted but somewhat nervous sketch bearing the title “Sketch for the Underground City” – belongs to an early body of work by Walter Pichler.
Working on abstract, hypothetical cities and buildings, Pichler questions the relationship of oppositional systems and investigates into positive and negative space, the designed and the found object, movement in space and movement of space. He is fascinated with infrastructure, spatial networks and the architecture of transition.

Over the course of four years he produced several series of drawings and objects, as the first seem to be mostly investigative and only occasionally presentation drawings, the latter are artifacts of meticulous craftsmanship in metal, concrete and plaster. Resting in time as singular entities, they obtain an almost transcendental aura; their painstakingly precise and slow process of making is inscribed into their abstract yet detailed manifestation. Form, space, light, material and surface are taken into the realm of fetish objects, the Sublime hovers within and around them.

The enigmatic objects are called Compact Building, Underground Building, Mouth of an Underground City, Core of an Underground City, Building over Infrastructure and Underground Building with extendable core. There is no record of an object titled the Underground City, the selected drawing solemnly bears that name.

Our model is neither abstract nor enigmatic but concrete. It is a model not an object. Its simple stereometric volumes are directly taken from Pichler's sketch. As a feasibility study it explores possible levels of detail Pichler's sublime objects would have faced, if they had been taken as representative model in an architectural process. The model is in search of the inherent beauty of the ordinary, it emphatically embraces the everyday, where the Sublime is just around the corner. Still, the Underground City remains the Other Space, pink cavities crouch underneath the surface.

The scheme is based on Edward T. Halls theory of proxemics, a study on the individual's need for personal space. To guarantee privacy within an open space, confidential conversations need to be protected by minimum distances.
The proposal embraces the conflicting requirements of openness and privacy and encourages customers to ascend to the upper floors.
A low-ceilinged Rustico welcomes the customer on street level. The ground floor is open to the public 24 hours a day and houses several ATMs. During business hours an extra-wide spiral staircase opens to a spacious Piano Nobile.
The structural system of the building consists of 13 slim columns and 5 waffle floor slabs. A service core contains ATMs, a staircase and an elevator.
Due to the cooperative heritage of the Sparda Bank the project indulges in humbleness.

Schloss Türnich is a unique spatial structure made from architectural and landscape elements. Together, they form a system of particular pieces: the castle, the moat, the French garden, the English landscape park, the mill, the forrest, the avenue and the agricultural land. The elements are not necessarily connected to each other and old connections are often interrupted by new elements.

This generous distribution of partially disjointed scenes - a recurring phenomenon throughout the history of the castle - is the main feature of the situation. The changes in the castle complex should therefore do justice to the special nature of the place. The connection between the castle, the village and the surrounding agricultural land should be achieved subtly via indirect connections; maintaining the autonomy of the subspaces and underlining their special atmospheres.

client: Architectura et Amicitia (Aeta)
date: June 2015

T'Huis in Breda by John Körmeling is a beautiful building. It is a pavilion in the park, largely constructed of glass with very delicate profiles and a very thin roof. You can enjoy coffee or tea on the terrace shaded by marquees. The marquees are red - like the terrace and the furniture, the artist uses a striking contrast; the park becomes greener seen from the red and thus more beautiful. T'Huis is proportioned using a golden ratio in ground plan and elevation. It is labeled with fluorescent letters, presenting the things offered here: ice cream, coffee, tea, sausage, cake and french fries.
The extension of T'Huis deals with the delicateness of the building. Any extension appears to be rude regarding the entity of the building's design. We know so many tea pavilions full of features: patio heaters or terrace glazing keeping smokers warm in winter; attached party tents opening after 5 o'clock for night use. Our extension also improves the functionality of the tea pavilion. It provides a small canopy and an additional door. The existing pavilion's toilet can now be used before or after the opening times of T'Huis. The door separating the cafè from the toilets is sealed. Now a machine on the outside of the pavilion grants the entrance. The canopy is tall so that it is visible all around the park and labelled with the service (WC) found here.

The Guest House project is based on BeL's personal experience as guests as well as temporary inhabitants of the Vandenbroucke residence.
Built fifteen years ago in the style of a fermette, the residence has been dramatically renovated by 51N4E. Their radical transformation opens the conventional plan to a multitude of functional programs. Gutting the existing house and adding an exterior space enclosed by a steel wall, the boundaries of exterior and interior are blurred completely. Domesticity is given a new significance, the fluid spaces offer a multitude of interpretations. In its ambiguity the house is an architectural manifesto and a home at the same time. It is a spatial portrait of the residents, an open house, happily awaiting guests.
With a guest program in mind particular functional limitations of the transformed residence become evident. Guests outside of the owner's personal realm intrude upon the latter's intimacy and have demands for their own privacy themselves. Two essential architectural shortcomings emerge from this programmatic friction.
The Guest House project enhances the functional performance of the house to meet the extra demands of a guest program. Additional space is generated within the existing building. The Guest House is not a detached or added annex but expands into the interior. It is extra space discovered inside of the building. It enables independence of individual users, supplying alternative spaces to be appropriated by guests and hosts.
The Guest House is a miniature house hidden within the existing building. It's a parallel realm of complementary space waiting to be occupied by either guest or host. It offers a diversity of rooms in a spatial continuum. It is small in scale, yet a whole new universe. Searching for the remaining voids left by 51N4E's transformation, the Guest House exhausts the building's volumetric capacity. With a minimum of alterations it strives for a maximum of space, retrieving surplus volume to residential use.
Challenging the visible and invisible thresholds of the occupants, the Guest House emphasizes their modes of dwelling and pushes the margins of cohabitation.

Balthasar Neumann Preis 2007 shortlist
As a non-hierarchical, uniformed, infinite and flexible space FRABA Sp. z o.o. is a metageneric production plant.
FRABA produces electronic components for the automation industry in a non-automated manufacturing process. The products are hand-assembled in small series. The assembly consists of tables, shelves and trolleys. The project FRABA Sp. z o.o. is a manufacturing facility prototype for an automation components company.
On a tight gross budget of 580€/m², a model for future expansions around the globe is developed. The design reacts to location specific construction and logistic conditions for each site.
In Poland there is a sufficient supply of timber at considerably lower costs compared to the equivalent conventional steel structure. The global steel market is overheated by Chinese demands which combined with low labour costs in Poland means a lightweight timber structure becomes reasonable.
The structural system consists of a 52m diameter 60° solid web beam grid. It rests on nineteen 17cm diameter stressed steel tube columns with a clear span of 9,70m. The shell is made of prefabricated insulated plywood elements, 14% of the roof is covered with triangular skylight domes. The top surface is aluminium coated bituminous roofing membrane. Gross floor area is 2069 m² with an overall clearance of 4,5m. The building has mechanical and conditioned ventilation, skylights are specifically designed for perfect daylight assembly conditions and avoid heat gains during the summer.
The circle is an optimized box. In comparison to a rectangular building of the same size it has less surface and less volume. Additionally to energety savings it allows savings of up to 13 % in construction materials. The triangular grid minimizes the construction material while offering a maximum of possible layout variations. The dimension of the triangular grid is adapted to the needs of the company. In terms of layout the triangular grid offers much more flexibility than the orthogonal one. It is optimised for the customer's production process as well as for possible future uses.

Grundbau und Siedler explores how lower income groups can become home owners. This project was originally developed in the framework of the IBA Hamburg 2013 for the urban district of Wilhelmsburg. The dominant typology in this area is the allotment garden hut, in the 1970s large social housing complexes were also erected there. Although the theme of these developments was "urbanity through density", they are neither densely built nor do they succeed in producing any sense of urbanity. The project by BeL stretches the typology of the hut to multi-storey housing – a skeleton provides the basic frame, its different storeys can be individually filled out, both spatially and over a period of time, by the residents themselves employing self-build methods. The future home-owners buy a package consisting of a plot within a basic, concrete-built skeleton, all the building materials needed to develop their plot, and a handbook giving detailed instructions on all the steps necessary for the development work. In warmer climatic zones Le Corbusier's Domino House principle from 1914 has proved its value as a successful construction system for informal housing developments. Aashwa´i in Cairo, Polykatoikia in Athens, Gececondu in Istanbul, and Favela in Sao Paulo confirm the superiority of the Domino construction principle – and not just from the viewpoint of costs. It is a shelf that provides ideal conditions for a mix of functions; a surplus of space creates a flexible basis to be appropriated by future extensions, conversions and adaptations. The open basic structure allows flexibility over a long period of time. Applying the Domino principle in Germany today requires specialized materials and details in order to satisfy the demands made by highly developed post-industrial societies regarding comfort, economy and ecology. The Grundbau or skeleton has a single staircase serving three units on each floor, the structure is five-storeys high and offers twelve sites for settlers. Each of the upper four storeys has three units, whereas the ground floor contains the settlers' private workshops, car parking spaces, the public utilities connection room and the approach to the open staircase. The settlers acquire a complete kit of building components to erect a typical settler's house. This kit contains all the construction material. A detailed handbook describes the steps that they can carry out themselves, as well as indicating those areas of work that must be approved by a specialist. The organization of the floor plans is independent of the load-bearing structure and the neighbouring storeys. All versions of the typical floor plan in the settlers' kit address different housing needs (the number of persons, lifestyle etc.) and changes of function over the course of time (a growing family, the advent of old age, change of user). A set of functionally neutral spaces is offered with an abundant number of doors. Consequently, the users can employ whatever function they wish. All the rooms are connected to each other; each room has openings to its neighbours. The large number of doors allows the rooms to be grouped as required. For instance: one family may want a large bathroom with a view, whereas another may use this room as a child's bedroom. Each dwelling has two service shafts that are positioned at the intersection of the partition walls and can serve three rooms. The settlers decide what the rooms will be used for. Flexibility results from use and not through adaptation. Functionally indeterminate spaces in a floor plan without corridors require the settlers to interpret and conquer their own space. In the 1:50 scale configuration model (contained in the building kit) the settlers can examine which ways of using the spaces work best for them. Those who wish so can ignore the recommendations and the material offered in the building kit and can improvise. Settlers can reject the guidelines within their own plot, everyone has the right to make their own mistakes and improvements. The Grundbau contains everything needed to build and operate a unit; the settlers can use the workshop spaces on the ground floor from day one and can run their own construction site from there. The Grundbau has railings making scaffolding unnecessary, the settlers can carry out their work from the 70-cm wide strip of balcony.

The conversion of a redundant multi-storey car park cautiously consolidates the neighbourhood with minimal capital and offers room for a community of 91 people. Construction costs of 828 € / m2 NF allow the tenant to pay a monthly rent of only 6.50 € / m2. The prototype can be used for all other car parks according to the d'Humpy scheme.

All measures to improve the substance of the car park are carried out with the principle of least intervention. The removal of prefabricated ceiling elements enables light to flood in from above via private courtyards, future flats are therefore basically lit from two sides. The car park is thus populated with courtyard houses. The system allows for a wide range of apartment types. Within the grid of ceiling panels, variations of individual types are possible.

A differentiated open walkway winds itself as a Rue Intérieure through the house, visual connection to the outside is possible everywhere, the light exposure is natural.

Along this inner street lie the private courtyard houses and public uses such as guest rooms, workshops, kiosks, bike rooms, a common room, benches and a space to barbecue. The rooftop forms the end point of the walk through the building via the ramps. The walkway and the common areas of the house offer opportunities for appropriation and adaptation.

Evolving from DIN display system ISO provides improved flexibility, rapid assembly time and minimized payload. Presented on a worldwide campaign the ISO universal system has to comply with numerous international standards.
ISO is nomadic architecture, it features lightweight elements, easy to carry and easy to assemble. Traditionally fabric is used to create shelters, ISO deploys a curtain/carpet made of customized injection moulded polycarbonate snap-on tiles.
ISO is a non-spatial concept. The elements can be applied in an infinite number of configurations on a multiplicity of trade fair lots. The possible organisational patterns are based on rules of proximity. Depending on the specific context the client can choose from a large array of possible set ups.
Iso is an attempt at nothingness. The spatial presence of the individual objects is reduced to the bare structural necessities. In an almost tribal simplicity, illumination is provided by lampposts. Tables and chairs have an intermediate height between chairs and bar stools to allow informal communication.
The grandeur of ISO's delicateness is a remedy to the barren environment of trade fairs. ISO is a satisfactory combination of austerity and pomp.

Esso Häuser
On the site of the former Esso Häuser a new part of St. Pauli has to be constructed: a mix of residential, commercial, creative and neighborhood uses.
St. Pauli is a neighborhood of Hamburg known for its red-light district and for its coexistence of extremes. Der Kiez is a unique biotope that offers room for many sub-cultures, one of the rare strongholds in the resistance against 'Disneyfication'.
The tenants were struggling for years to save the Esso Häuser from demolition. After a forced eviction in December 2013, the protesters focus switched towards securing the return of tenants to a new building.
Under the auspices of the so-called PlanBude an intense participation process with the citizens of St. Pauli has taken place. The results from this exceptional bottom-up process formed the basis for a competition among nine internationally renowned architectural firms to envision an urban plan for the now vacant plot of slightly over 6.000 m² on the Reeperbahn in Hamburg.

St. Pauli Code
The preliminary process involved over 2000 contributions by St. Pauli residents and others involved. The PlanBude, strategically located directly next to the building site, has unravelled the St. Pauli Code by conducting interviews, collecting ideas and opinions and by 'engineering' a number of innovative and artistic planning instruments. The use of clay for instance to model fantasies proved to be a fruitful tool. To remain in proportion, the density of the specific malleable substance was translated into a volume; all participants were given a lump that represented the exact required building mass. Simply brilliant.

The St. Pauli code in short:
1. Diversity instead of uniformity
2. Small-scaledness
3. Affordable instead of expensive
4. Originality and tolerance
5. Appropriation and vitality
6. Experimentation and subculture
7. Public space sans consumerism

program: conversion of a 29th floor penthouse into a photographer's office

At 134m height, the Uni-Center in Cologne is one of the largest residential high-rises in Europe. In addition to 1000 apartments, it has several office and service areas. The 250 m² penthouse, previously divided into 5 office units and located on the lowest wing with 29 storeys, was dismantled and a few structurally strategic elements were added. In addition to a bathroom painted in neutral gray and a technical room, it is a fully glazed large room with a core made of exposed concrete. The glass facade was completely replaced by energy-efficient elements and provided with a large sliding system to the east of the roof garden. 

The conversion deals with perspective as a symbolic form. An approximately 90 cm high platform takes up most of the space. Under the platform there is a large number of cables behind shelves, these dominated the room before the renovation and are now combined with the existing core. The platform divides the room into a low-lying zone along the facade and a wide, coherent area above. Above are the permanent workspaces, meeting tables and a sitting area. The floor of the platform is covered with a specially designed and manufactured carpet, which, in reference to oriental patterns, contains ornamental elements such as the floor plan of the Unicenter, the coat of arms of the building owners birthplace, and maritime motifs from the Gaudi tile used in the tea kitchen.

In raising the floor by 90 cm, the breathtaking panoramic view extends over the balustrade of the roof garden - which is very high at 115 m - to the horizon. The world is at your feet.
