Modern Shed-Style Tiny House Plan with a Large Deck

This 16×20 small house plan delivers 320 square feet of single-level living plus a generous 200-square-foot deck. With everything on one floor and no stairs to climb, it makes a comfortable weekend cabin, a guest house or ADU, or a light-filled home office.

Exterior and outdoor space

A mono-pitch, or shed, roof gives the home a sloping profile and lets the ceiling rise toward the tall wall of glass. Expansive sliding glass doors open straight onto the deck, so the 200-square-foot platform becomes a true outdoor room for grilling, coffee, or relaxing in the sun. A flue on the roof serves the wood stove shown inside. As shown, the exterior is finished with vertical wood siding, though the choice of finish is yours. The glass and deck earn their place in a small home, keeping the interior bright and open to the outdoors instead of closed in.

Interior layout

The single open room joins the living and dining area with an open sleeping area, so the whole floor lives larger than its footprint. A galley kitchen runs along one wall, keeping counter, cooktop, and storage in an efficient line that leaves the main space clear. A full bathroom with a soaking tub sits behind it, a real comfort you rarely find in a home this small. Single-level living means no stairs and no loft ladder, which keeps the plan easy to move through at any age.

Versatile by design

One footprint, several uses:

• Weekend cabin: the wood stove and deck make it a genuine four-season escape.
• Guest house or ADU: a full bath with a tub gives visitors a proper place to stay.
• Home office or studio: the wall of glass and step-free floor keep the workday bright and easy.

Pick your finishes and make it yours.
