GuestHouse50

Located near the historic center of Luxembourg City, in a popular neighbourhood, the building from 1880 with 1930s annexes once accommodated a decorating store and stucco workshop. GuestHouse50 now hosts a flexible program of pop-up shops, exhibitions, yoga classes, workshops, and shared meals on the ground floor, with guest rooms above. This socially sustainable reuse turns a former modest townhouse into a space of exchange as a shared urban living room. Restored with natural materials, it offers a warm, tactile atmosphere that connects daily life to the traces of its past.

In a row of modest late-19th-century houses, number 50 was destined for demolition by investors seeking to rebuild for short-term gain, erasing local identity and coherence. The challenge was to counter speculation and prove that renovation could be a viable, forward-looking alternative. Instead of yielding to market pressure, we sought protection from the State Ministry of Culture to obtain financial support and recognition of its cultural value. What began as a single request became a turning point: the Ministry’s decision to extend heritage status to the adjacent houses sparked public debate and revealed the tension between preservation and profit. GuestHouse50 emerged as a beacon of preservation - an act of collective responsibility and urban sensibility. Our approach combined design precision with cultural awareness, turning uncertainty into opportunity and showing that private renovation, though challenging, can restore meaning, value, and cultural life to the existing fabric.

Old houses were built from what was close at hand: stone, sand, wood, and tiles, simple materials shaped by local knowledge and time. To erase such substance would have been the least sustainable act; instead, the project chose continuity, preserving the existing structure and refining the building through minimal, precise interventions. Each addition was a gentle extension of what was there, reducing waste and embodied energy. Inside, natural materials such as Miscanthus-clay insulation, lime plaster, terrazzo, and oiled oak were used not to disguise the old, but to let it breathe and live anew. This dialogue continues in the restored elements: doors, wooden floors, mural wallpapers, and the staircase, whose patina was preserved through gentle repair. The guiding principle, both for the project and its future maintenance, is to preserve and repair rather than replace: a way of building through care, where preservation, simplicity, and time become the real measures of sustainability.
