Fairly furnished warehouse, each floor is 4 tiles tall (the top floor has the ceiling so not completely 4 tall in every space). Crane in the front and a crane inside in the back corner. There is a mid-level leading up to the 2nd floor with some small storage, and the stairs to the basement are 2 tiles wide. Front gate opens to allow large volumes in and out.

This warehouse was designed for my campaign’s not-quite-wealthy town, so the structure is made of sturdier materials near the bottom but cheaper/more abundant/lighter wood as it goes higher.

12 tiles by 12 tiles, excluding front bit.
12 x 16 including grass section and crane.
