Miter Box Tiny House Plans


A Modern Retreat or Minimalist Flat

The Miter Box was one of the first modern, energy-efficiency-focused tiny houses. It’s a compact house, with 122 square feet on the main floor and a 28 square foot sleeping loft. Its simplicity, clean lines, and sharp contrast are a modern twist on classic childhood drawings of a house. The name was inspired by the carpenter’s miter box and the design’s corresponding attention to detail, intersecting lines, and precise commingling of warm wood and cool metal.

The interior has one counter, one shower, one sink, large amounts of storage under the salon seats, and additional storage in the small loft above the entrance and bathroom. The full bathroom has space for a composting or conventional toilet, shower, and medicine cabinet.  The dining area is sized to convert into an additional double bed for single-floor living or guest accommodations.

The original model was constructed with $22,000 in materials, yet created a warm, inviting space in a clean, elegant design.  Step into your future and relax in this modern tiny house design.



What the Miter Box Tiny House Plans Include

  • Trailer specification and connection detail (including wheel wells)
  • Detailed technical insulation envelope system (including insulation schedule)
  • Framing details & diagrams for the floor, trailer, windows, doors, walls, lofts and roof

These plans do not include interior design details (other than suggested dimensions) or a materials list. The beauty of these plans is that they contain all of the essential nuts and bolts to get you a solid, extremely energy-efficient tiny home that is completely customizable to your tastes.  Please note that the Miter Box uses advanced construction techniques, and we recommend that only experienced builders tackle this design.

Weight and Trailer Recommendations

The Miter Box was designed for a 16 foot, six inch long trailer (16′-6″) but can be easily converted to a 16 foot or 18 foot house by subtracting or adding slightly to the open living space. Iron Eagle Trailers builds our favorite tiny house trailers out there, and Derin from Shelter Wise and Dee from PAD even helped them design their trailers to be perfect for tiny homes.  Tell them PAD sent you, and you’ll get $50 off your order.

Build Smart!

With all of our plans, we recommend a copy of Go House Go, our how-to manual for building a tiny house on wheels. It’s the book Dee wished existed when she built her little house, and she wrote it to save everybody else all the time and trouble that she went through to figure out how to build smart and safe.
