I have completed this TARDIS Little Free Library cabinet for a client in Illinois.
It stands 28 inches (71 cm) to the top of roof, 32 inches (81 cm) to top of lamp. The footprint is 16 inches x 16 inches. (40.5 cm x 40.5 cm)
The lamp is solar powered and the top signs and PTO sign are printed on aluminum.
