Walls painted white - matchsticks added to represent wood (still in process on the pic above and below).
Woodwork finished: windows&door glued up - windows are a bit simple, the door is from that type of cardboard which is used in stores to pin shirts on them - marked with a run-out ballpoint pen to look more wood-like. Ironings are simple paper glued on + a bit of a brown paint to get the look more wooden-like.
Macro of the door. Put some sand+varnish stuff to the base, may paint it later.
After all, this is quite simple work with 1-2 hours of effort containing the time needed to glued parts to stick firmly - would fit any tasks if buildings are needed.
