Suitable building type for labour accomodation

edit

I'm modelling three labor accommodation buildings consisting of two floors each, and each floor having having 16 rooms. I could not find a suitable building type. I found 'Midrise apartment' but it doesn't have suitable space types matching my need such as living room, restroom, stairs, mechanical/electrical rooms.

Could anyone suggest how can i find a suitable building/space type matching my need. I tried searching BCL if there are any similar building/space types such as 'hostel', but I could not find one. Appreciate your help.
