Here is a mudroom Drew did.
As always before pictures were an after thought. Basically this was just a long room with no storage.
Drew built two tall cupboards for vacuum, brooms and mops. A bunch of smaller cubbies with individual slats, to hold stuff in, but be able to peek through and see what's in there.
The other side has different size shoe cubbies to store big boots, to little shoes. Above are more cubbies. And the middle is a bench seat and beadboard with individual hooks for coats.
All built in our garage.
