22' Clear-Span Truss & Slab Engineering
A 22' × 40' rectangular building envelope (880 sq ft base area, 124 linear feet of exterior wall) is one of the most cost-effective structural modules in residential construction. Because the 22-foot width can be spanned by single-piece prefabricated wood roof trusses or cold-formed steel rafters, interior walls are non-load-bearing—allowing complete flexibility between open great rooms, split bedroom wings, and drive-in garage bays.
Material Takeoff Baseline (14 Cu. Yds. Concrete / 11 Roof Squares)
Every 4-corner 22x40 layout eliminates expensive hip-and-valley roof framing and minimizes foundation form corners. Builders typically budget 14 cubic yards of 4,000-PSI concrete for the monolithic slab, 105 exterior 2x6 studs (or 16 laminated post-frame columns at 8' o.c.), and 11 squares of standing-seam or ribbed metal roofing.
How many bedrooms and bathrooms fit inside a 22x40 (880 sq ft) floor plan?
A 22' × 40' building footprint (880 sq ft base area) comfortably supports 1 to 3 bedrooms and 1 to 2 bathrooms, or a 1-to-2 bedroom layout with an integrated garage/workshop bay. Browse all 22 vetted 22x40 floor plan variations above to compare room sizes.
How much concrete and roofing material does a 22x40 building require?
A 22' × 40' footprint has 124 linear feet of exterior perimeter wall. Pouring a 4-inch monolithic concrete slab with thickened perimeter grade beams requires approximately 14 cubic yards of ready-mix concrete. A standard gable roof with 18-inch overhangs requires roughly 11 roofing squares (1,100 sq ft of metal or shingle coverage).
What is the average cost to build a 22x40 house or barndominium?
Across our 22 engineered 22x40 blueprints, dried-in structural shell packages range from $26,400 to $42,240, while full turnkey construction averages $152,773 depending on whether the footprint is configured as all-living space or split between living quarters and an unheated shop bay.
