Kost houses are usually built to fit as many rooms as possible, and that crowding often comes at the cost of circulation and natural light.

Every room here was given its own window, a non-negotiable starting point rather than an afterthought. Roster walls open up circulation routes throughout, letting air and light move where a typical kost layout would otherwise feel sealed off. The result stays minimalistic, with a single brick wall carrying the accent for the whole façade.
