aerial photos

To me & no expert that type of housing spreads across NE Africa, also similar India Afganisatan etc though perhaps larger more uniform.
Often laid out on 2 or 3 sides of a square L LI perhaps with a 4th wall giving a courtyard if large.
When I did have photos though 2rd wing was often mainly just walls. Remember this because upon looking seemed an open air lounge & kitchen was reasonably common in the better buildings presumably with roofed duplicates, made sense esp cooking in a hot climate.
Lost the pictures was years ago but same textures & flat roof apply.
Build the first bit then an add another wing when you can?
