The Capitol Hill Shop is a 1/4" scale laser cut kit. The Interior (see photo below) is divided into two rooms - the larger main room is 4" wide & 3-1/2" deep - the smaller room is 2-1/2" wide & 2-1/2" deep - the exterior width of the shop is 7" long. Everything is included in the kit (except the paint and glues) to complete the structure as shown - including the LED lights, battery pack, wallpaper, stain glass window grapic etc. You will need to supply the glue, paints of your choice and basic tools. The battery pack for the LED lighting is hidden in the pull out drawer in the "basement". Capitol Hill is lit by 2 MEGA LED lights. Step-by-step directions include lots of color pictures, diagrams of the pieces & how to wire the LED lights into the battery pack. See additional photos below for the interior & side views.
