I'm going with a turn of the century saloon style, with bar and stools/ high end cigar bar w/ sectional pleather couch with stinkys and glass top coffee table. With coffee bar in the corner.
Dual flat screens. Neon lights, oil sconces. Crosley juke box Cedar wall covering (cutting my own). fish mounts, animal mounts, cathedral ceiling. Rocking chairs on the porch.

24x16 and I need a small central air system so I can keep my gars out there.
Or heat pump. Run ducks through floor.

The Herf Shack is my light at the end of the tunnel
