Is Tiny Home Tool a free tiny home designer?

Yes. You can design and preview an A-frame or shed-roof tiny home in 3D for free. When you finish the design, the generated drawing, cut-sheet, material and project-file package is unlocked through the one-time checkout.

Does Tiny Home Tool create permit-ready plans?

No. The drawings and estimates are concept-planning information and must be reviewed for the site, structure, loads, codes and permits by qualified local professionals.

Can I design an A-frame loft and floor plan?

Yes. The designer provides separate main-floor and loft-plan views with true-scale furniture and preliminary headroom checks.

Does the material estimate include exact store prices?

Material costs use planning defaults. The detailed CSV allows users to replace unit prices with current local prices so spreadsheet totals recalculate.

Start at the floor or raise the side walls

One choice changes the whole frame. Above 2 ft, the tool automatically adds either the selected loft framing or visible rafter ties, plus doubled knee-wall top plates.

Underfloor protection Included

Rodent-resistant underside sheathing

Adds an exterior-rated underside barrier and fastening allowance. Final moisture, drainage, ventilation, and pest detailing still require a site-specific assembly.

Inset end walls Covered entry

Front wall inset (ft)

Rear wall inset (ft)

Entry-inset side walls

Optionally recess an end wall inside the roof footprint to create a roofed entry recess. This is part of the house framing—not a separate deck feature. Floor joists continue to the outer rim and roof lookouts extend to the fly rafter.

Optional loft Step 4

Choose how much of the cabin length the loft covers. Every loft joist still spans fully side-to-side; exposed sections keep the required visible rafter ties.

The tool will check usable headroom and whether a twin mattress fits.

Interior walls & rooms Square snap

Bathroom modules start at a practical minimum size, include their fixtures, and can be moved, resized or rotated. Full baths include a shower; half baths do not.

Each partition can have a different finish on each face. Walls stay square at 0°/90° and can carry standard, barn, or pocket-style interior doors.

A-frame mode includes a ridge cap; shed-roof mode uses high-side flashing instead of a ridge.
