Like at all Foundation sites, Site-77 rooms are simple fare. Each person on the site has their own room, containing a bed, a desk, a bedside table, cabinets, and a poster reading "Mankind Must Not Go Back To Living In Fear". The rooms all have an attached bathroom, and a very small kitchen. Each door has a simple but secure locking mechanism, and is labelled with the occupant's name.
There are many common rooms split amongst the Site's departments. As an active field MTF, Psi-7 has one of the nicest, equipped with several sofas and armchairs arranged around the cutting-edge color television. In one corner sits a piano, and in the other the jukebox. Agents are encouraged to spend as much time in the commons as they wish, although sleeping is discouraged.
