16 x 32 modular with 3 floors in (Dutch) colonial style. Ground floor has a scuba shop to rent out scuba dive gear. In the back a shower area to rinse off the salt water after a dive. 2nd floor has a working air compressor with pneumatics! It is operated by hand outside the modular. An attic with storage space completes the modular. This modular has a working service lift that can reach all floors and is operated by hand. A while ago I acquired my Padi diving certificate on St. Statia so connecting the Caribbean design with a Scuba Shop seemed logical.
