- Legos, 2x2 used here (has 4 nubs).
- Mat board scraps from a framing shop
- Hot glue gun
- Black cloth tape (friction tape or gaffer's tape)
- Acrylic paints in desired colors
Sides are hot-glued onto the Lego core, then additional pieces added behind the window openings. Black "panes" are inked in. Doors are glued on the outside. Glue on the roof and apply black cloth tape for texture.
Stack some more Legos and snap into the bottom to make a temporary painting handle.
Grey acrylic paint is applied unevenly to the roof to simulate weathering.
On larger buildings, use Legos to keep the corners square and to provide a gluing surface.
