28' × 40' Build Cost Guide, Nearby Sizes & FAQs

Slab takeoff, framing span notes, and comparable footprint sizes

28' Clear-Span Truss & Slab Engineering

A 28' × 40' rectangular building envelope (1,120 sq ft base area, 136 linear feet of exterior wall) is one of the most cost-effective structural modules in residential construction. Because the 28-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 (18 Cu. Yds. Concrete / 14 Roof Squares)

Every 4-corner 28x40 layout eliminates expensive hip-and-valley roof framing and minimizes foundation form corners. Builders typically budget 18 cubic yards of 4,000-PSI concrete for the monolithic slab, 116 exterior 2x6 studs (or 17 laminated post-frame columns at 8' o.c.), and 14 squares of standing-seam or ribbed metal roofing.

How many bedrooms and bathrooms fit inside a 28x40 (1,120 sq ft) floor plan?

A 28' × 40' building footprint (1,120 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 41 vetted 28x40 floor plan variations above to compare room sizes.

How much concrete and roofing material does a 28x40 building require?

A 28' × 40' footprint has 136 linear feet of exterior perimeter wall. Pouring a 4-inch monolithic concrete slab with thickened perimeter grade beams requires approximately 18 cubic yards of ready-mix concrete. A standard gable roof with 18-inch overhangs requires roughly 14 roofing squares (1,400 sq ft of metal or shingle coverage).

What is the average cost to build a 28x40 house or barndominium?

Across our 41 engineered 28x40 blueprints, dried-in structural shell packages range from $33,600 to $53,760, while full turnkey construction averages $191,756 depending on whether the footprint is configured as all-living space or split between living quarters and an unheated shop bay.
