Build difficulty

Straightforward

Straightforward. Single ridge and a simple roofline, but the 40 foot span still calls for engineered trusses and a lift to set them.

A small experienced crew can frame this. Slab, posts, and trusses are the whole structural story.

About this plan

Mill Wheel is built around easy daily living. A covered porch runs across the front of the house and a second one runs across the back, so there is always a shady side. The front door opens into an entry with a mudroom beside it that connects straight to the two car garage, which has a 10 by 7 workshop and the mechanical room at the back. Past the entry, a 21 by 17 living room has double doors out to the back porch and flows into the dining room and a kitchen with an island. A 7 by 9 walk in pantry and the laundry room sit just off the kitchen. The primary suite has a walk in closet and a bath with a shower and a double vanity, and Bedrooms 2 and 3 share a hall bath with its own double vanity. Outside it is lap siding with square porch columns under a metal roof. Good to know: the bedrooms are not split, and the workshop is a small room inside the garage, not a full shop.

The structure is post frame, so the load path is simple and the interior walls are mostly partitions. That matters when you want to move a wall later, and it matters when a framing crew prices the shell. 3 bedrooms and 2 baths sit on one level, with 2 garage bays.

What you buy here is the document set. It is not a home, not a bid, and not a price to build. Your cost depends on your county, your site, your finishes, and who swings the hammer.

This is a national range based on reported completed projects, not a quote. Your actual cost depends on your county, your site, your finishes, and who swings the hammer.

Modify this plan

Most buyers change something. Move a wall, stretch the shop, flip the entry, swap the framing. Send us what you want and we come back with a written scope and a dated range before any drawing starts.

Changes to this plan are priced by tier and drawn by American Barndos. If what you want is closer to a custom design — a different footprint, a different span, something drawn around your site — the request goes to National Barndos, and starts with a one-hour design consultation, $497. The same form covers both; pick the scope that fits.
