With the LYSP8 project in Basel, Loeliger Strub Architektur and Zirkular GmbH are sending out a strong signal for sustainable construction in the urban context. From the outset, the residential and commercial building pursues a clear objective: to reuse as many building elements as possible from existing buildings - in other words, not to consider reuse as an afterthought, but as an integral part of the design process. The result is a lively ensemble along Lothringerstrasse, comprising a long building and a punctual house on the square, linked by a striking wooden structure that serves as an open service structure and social meeting space.
Many of the elements built - including facade cladding, windows, doors, kitchens, balustrades and even tiles - come from deconstruction and have been carefully recycled. This not only saves resources, it also avoids large quantities of CO₂ - estimated at around 250 tonnes compared with conventional construction. Traces of previous use remain visible: traces of use, patina and the diversity of materials tell their own story and give the new building a special depth and character.
Architecturally, LYSP8 is characterized by an open, community-oriented structure. Courtyards, niches, terraces and a public rooftop pavilion encourage encounters and exchanges between residents. The roof pavilion can be used flexibly - as a guest room, winter garden or outdoor kitchen - and underlines the idea of a shared living space. At the same time, attention was paid to compact, energy-efficient planning: the apartments are arranged so that a maximum of 45 m² of heated surface area is required per person. In summer, the open wooden construction acts as a natural sunshade, further reducing energy requirements.
LYSP8 is an exemplary example of how reuse, social sustainability and architectural quality can merge. It is a model project for a new, resource-conscious building culture - unconventional, courageous and at the same time realistically achievable.
