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?

A market square in the middle of a historic town center characterized by half-timbered façades and red sandstone has lost its spatial definition due to war damage and subsequent demolition, but nevertheless enjoys constant use. The proposed market roof mediates between the two levels of the market square and the church forecourt. It also provides shade, weather protection for the market and for people to gather, as well as serving as a collector for rainwater. Based on the concept of the sponge city collected water can drain away into an unsealed square and serve as the basis for a tree canopy, which in turn protects the urban space from overheating. The new sandstone pillars are milled in the shape of tree trunks, the copper roof resembles the roof covering of the church, a simple wooden construction in between is linked to the immediacy of the half-timbered façades.

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.

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.

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.

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.

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.
