This would be really cool as a cross-section of a room or tiny house with some different areas highlighted or called out.
Storage spaces up high: Use shelves to add more storage up high.
Storage spaces down low: Don’t forget about low-to-the-ground storage.
Seating low to ground: Low seating can be stored easily and saves space.
Curtains or barn doors to slide open/closed: Change the room around with curtains or a barn door.
Mirrors: Mirrors reflect light and make the whole space look bigger.
Wall-mounted television: Don’t bother with an entertainment stand; mount that TV to the wall
Stackable appliances: A tiny washer and dryer that stack let you do laundry and save space.
Natural light/windows: Natural light also makes your space look bigger; skylights are perfect for this.
Neutral colors: Too much color can make a room feel crowded. Go neutral to maximize space.
Fold-out desks or dining sets: If you’re not using it, can you stash it? Invest in foldable furniture.
Outdoor relaxation areas: Fix up the great outdoors for another place to sprawl out and relax.
