A/NTERIM is a Swiss Real Estate PropTech, specialising in the sustainable transformation of vacant properties.

We offer a smart and flexible solution for pre-construction and underutilised spaces by converting them into furnished, short-term co-living homes—primarily for students, expats, and working professionals.

​

Since 2023, we’ve helped developers, investors, and property owners bridge vacancy periods with minimal effort and real return. Our interim use model brings life into empty buildings, prevents decay, and supports urban vibrancy—without long-term commitments.

​

At the same time, A/NTERIM is expanding into long-term co-living concepts, offering fully operated, income-optimised residential units for landlords who want higher returns and lower vacancy risk. Through a room-by-room rental model and full-service operations, we turn classic flats into managed, multi-stream assets.

​

With our lean structure, strong partner network, and commitment to transparency, we offer owners a new level of confidence and control—while delivering tenants high-quality, community-oriented homes in prime locations.

​

Vacancy becomes opportunity. And space becomes value.

Let’s rethink what property can do.
