Modern Leanto

A modern leanto has a single-slope roof: one roof plane that slopes from a taller wall down to a shorter wall.

The clean, simple profile works for barndominiums, shops, garages, and backyard casitas.

Choices to discuss for your building

These are options to talk through with our design team. Each project is engineered for its site, and not every option is part of every kit.

Size

Width and length to fit your property and how you will use the building.

Wall heights

The tall and short walls set the roof slope and the room inside, for example for a loft or taller doors.

Doors and windows

Sizes and approximate locations of roll-up doors, entry doors, and windows.

Living or shop use

A home, a shop or garage, or a mix of both under one roof.

Porches and covered areas

Some models add a covered porch or carport along one side.

Your site

Local snow load, wind speed, and frost depth requirements from your planning department.

What the kit includes

  • Fire resistant, mold resistant, termite resistant steel framed eco structure kit
  • Engineered plans for both the building and the foundation
  • Door and window frames sized for your requirements
  • Structural bolts, braces, painted screws, and sealants for assembly
  • Wall framing, roof framing, and exterior steel for the walls and roof

The actual windows and doors are not included.

Foundation plans and the foundation

Your kit comes with engineered foundation plans. The physical foundation is built by your local contractor, working from those plans.

Construction on site and interior finishing are done by you or your local builder.
