Some ideas after building a mock up

Side Window
-two siding panels in glass
-tinted
-solar collector

Front exterior door
-slides into wall
-possibly on a arced track
-screen door on same track

Angled Ceiling to transition toward back
-padding at exit

Separate door or panel to separate bed area
(helpful when cold outside)

Fold down bench in changing area
-fold down table to watch tv and eat dinner

Hammock
-that works both as a bench and place for storage

Front area needs to be larger than mocked dimensions

Tv
-on ceiling
-folds down on track

Mirror in the changing area

Exterior hammock stand

Separates into two sections to fit into freight elevator
