A vacant WBS 70-type residential building in Leipzig presents a unique opportunity and is being temporarily occupied for housing research. To this end, we are setting up a residential demonstrator in parts of the building. The demonstrator is intended to implement the ‘nucleus living’ housing model within the existing building stock for research purposes. This will be tested and evaluated over several months (in the summers of 2026 and 2027 respectively) with trial residents. In a previous research project by the Chair of Housing Construction RWTH Aaachen, the standardised WBS 70 floor plan system was examined and its potential for contemporary and flexible forms of living demonstrated. The real-world ‘Nukleuswohnen Leipzig Grünau’ project now builds on this research and is complemented by several PhD theses on specific topics such as innovative building components, acoustic well-being, diverse family structures and the significance of individual (living) spaces – all within the context of communal living. At the same time, the aim is to create a (temporary) space for public discussion on issues of housing sufficiency, the use of existing stock and smart renovation strategies, both for the neighbourhood’s residents and for stakeholders from politics, the housing sector and research.

The exhibition at the Weissenhof Architecture Gallery shows a selection, interconnection, and associative evolution of merging prototypes from three ongoing projects. It represents one of many working methods that interest us: That of on-site design based on the tangible object. We grapple with it, search, solve or develop problems that we may only overcome in the next prototype. Nevertheless, we enjoy the vague state of the interim result, not knowing whether it is perhaps “finished.”

A 19th-century half-timbered house in the Odenwald is being upgraded to meet contemporary standards of energy efficiency and sound insulation. At the same time, the aim is to give its somewhat confined interiors a greater sense of space. We are developing a straightforward box-window construction and building a fully functional 1:1 prototype ourselves to test its suitability for 13 further window openings within the same building. By projecting the box frame well beyond the wall, the window sashes can open through 180° without intruding into the small rooms characteristic of traditional timber-framed houses, so they can stay open during summer. The slender profiles and the extended sash frame – which also serves as a handle – give the window a more pronounced vertical proportion than its actual dimensions would suggest. The insulating glass unit is structurally bonded directly to the frame and held in place at selected points by glass retainers. This construction echoes the direct expression of joints found in traditional timber framing, while the absence of conventional glazing beads further reinforces the verticality of the element.

A young family wants to transform a house used as a hotel within a historic town center to suit their ideas of living. Rather than using a pre-defined concept, the conversion explores ways of dealing with demolition material, financial resources as well as the urge to only use wood or re-used material for the all structural interventions. Therefore we reject constructive clarity, a binary distinction between new and old and formal coherence in general. The conversion aims to understand the chronological and constructive layers of the building as simultaneous and perpetuates this through reinterpretations, such as the revaluation of recycled marble window sills as ornament, the vagueness of the static interventions, the distortion and imitation of the existing, the superimposition and merging. Thriftiness is unexpectedly found in generosity – room-high doors save lintels, the interwoven ground floor even saves entire doors, the simple flat glazing of an old doorway saves masonry.

A comparison of recent competitions for cantonal schools in Zurich from 2022 – 2024 shows that, on average, a ratio of approximately 1:5 between sealed area and floor area is achieved. Our project proposes to achieve cost, construction time and CO2 savings of 10% by achieving a maximum ratio of sealed area to floor area of 1:10 and thus minimising the underground volume. This reduces solid construction – usually reinforced concrete – to an absolute minimum within the plot and the necessary program. A large part of the costly sealing, excavation and shoring structures is also eliminated. These economies allow an optimised construction time, as the comparatively small underground area plus the column foundations can be erected quickly and all upper floors can be highly prefabricated as fully demountable timber-steel hybrid constructions. In this case, the economic advantages go hand in hand with the ecological benefits. The ambitious target of a maximum of 1:10 sealed area to floor area can become a model for cost-effective and CO2-optimised school buildings and represents the core statement of the required ‘pilot project’. But what does the maximum reduction of underground areas mean for urban planning, landscape and architecture?

Soil and water are fundamental resources of the city that need to be protected. Both are present on the site, but are hidden under asphalt. The project proposes to unseal the site over a large area and to seal less area than before with the construction of the new building. The result of ths idea is a timber construction that is almost completely elevated above the ground, rising from the terrain, with only the shelters required by building regulations in the ground. The small, naturally formed body of water is preserved and maintained as a retention and climatic area. It may not always be obvious, but even in the unused and unmanaged spaces of cities, there are complex relationships that are worth protecting.

The blurry space of a newly emerging city offers the opportunity to question familiar urban forms. The constellation of the three houses constitutes a place of its own within the rigid development plan without fundamentally questioning it. Their connecting space combines the idea of an urban square with that of a wild garden, while the adjacent façades react situatively to the surrounding spaces. Access zones and uses are oriented towards the interior and interweave public and private space with the site. Living thus fits organically into a larger context instead of closing itself off to the outside. Through the interference of the spatial and constructive layers, the three buildings are shaped from the inside to the outside as a sequence of breathing, ever-changing spaces that remain permeable in their use and form rather fluid than purely distinctive and static conditions.

Belonging deals with proximity and distance, to the people we surround ourselves with, to the spaces we want to inhabit, but also to thounsands of objects. Belonging, inclusion, and exclusion are social processes that constantly shift in form and must be negotiated both collectively and individually. From a design perspective, we are interested in how the collective and the individual can be integrated into a creative process, and how this dichotomy of authorship might be overcome through design. For this, we wish to borrow a method from Surrealism, the Cadavre Exquis. The uniqueness of each individual merges into yet another unique whole. Still, the whole is not a randomly assembled mixture; interfaces must be discussed and defined, boundaries drawn or dissolved. For as much as we value the individual, it often makes sense to share desires and ideas (that is, resources). One is almost tempted to recall Alexandre Dumas’ often-quoted phrase: „One for all, all for one.“ The aim of the workshop was the group creation of various cadavre exquis. The starting point were unwanted or unsuitable objects from participants’ personal surroundings. Through continuous exchange and ongoing manual transformation, each author enriched the cadavre with new perspectives and expertise, while keeping in mind the connections to the other parts. With this method, we aim to explore how alienated objects can once again become desirable, by learning to see them through others’ eyes and by combining newly found perspectives in a collective creation.

The dominant model for explaining the world relies on a binary system: observations are categorized as either A or B, black or white, being or non-being. In short, this model adheres to a strict dualism rooted in the two-valued logic introduced by Aristotle. But how can we account for contradictory, opposing, or non-binary phenomena – particularly in architecture? Early efforts to translate this question into architectural discourse can be found in the work of Doris and Ralph Thut, who in turn draw on Gotthard Günther’s concept of a many-valued — or polycontextural — logic. Together with students, we tested a research-based approach to applying these questions to the architectural component of the door, taking into account flexibility in residential construction in existing structures. We were working on a 1:1 scale using merely donated doors and materials.

As part of a design studio at the HTWK Leipzig, we worked with 5th semester Bachelor students to identify methods and strategies that represent a heuristic approach to dealing with damaged buildings. Using a variety of (actually still undamaged) existing buildings in Leipzig, we explored the potentials of decay in terms of design, taking an interest in different building types as well as the gradual change in the damage. The design process was not aimed at a pre-defined goal of restoration or repair, but was understood as a continuous expansion around loose ends in three stages of escalation (minor, capital and total damage). In parallel to the growing extent of the damage, the scale of the intervention was also gradually adjusted. While the first step was still a spatially isolated detail, it then evolved into a spatial-structural intervention and finally into an intervention affecting entire parts of the building, so that by the end of the semester an equilibrium had been reached between the damage and the existing building, in which the parts could no longer be separated and everything had merged with everything else. This reversal of the classical architectural liturgy from the large to the small scale, from urban planning to detail, was accompanied by a reinterpretation of the forms of representation. The model took on the function of both a sketch and the final workpiece. The plans matching the scale of the intervention were then created retrospectively on the basis of the model as a simple hand drawing on tracing paper.
