Plan HG-1512 (1,040 Sq Ft (26x40) 2 Bed 2 Bath Barndominium Floor Plan with Shop) is an IRC R304/R310-vetted barndominium blueprint engineered around a 40'-0" × 26'-0" structural grid (1,040 sq ft base footprint, 0.65:1 Square-Bay Proportion). Configured on the Side-Bay Shop + Wet-Core Mudroom Buffer topology, this layout delivers 676 sq ft of conditioned residential living area paired with a 364 sq ft fire-separated workshop/garage bay and 208 sq ft of covered outdoor porch deck.

Inside the conditioned envelope, the floor plan is organized into 6 distinct architectural zones: 1-BAY SHOP / GARAGE (14'-0" × 26'-0", 364 sq ft), PRIMARY SUITE (13'-6" × 11'-6", 155 sq ft), BEDROOM 2 (12'-6" × 11'-6", 144 sq ft), GREAT ROOM & DINING (16'-0" × 14'-6", 232 sq ft), BATH & MUDROOM (10'-0" × 6'-6", 65 sq ft), KITCHEN & ISLAND (10'-0" × 8'-0", 80 sq ft). Plumbing rough-ins are consolidated across BATH & MUDROOM, KITCHEN & ISLAND to minimize sub-slab trenching and manifold pipe runs. Sleeping quarters (PRIMARY SUITE at 155 sq ft; BEDROOM 2 at 144 sq ft) are acoustically buffered from the primary living core and positioned on exterior elevations for code-compliant egress glazing.

From a builder takeoff standpoint, the 40' clear-span width utilizes cold-formed steel / post-frame clear-span trusses (8' o.c.) bearing on 132 linear feet of 6" exterior wall framing (~160 framing studs/posts) and 111 linear feet of interior partitions. The 4:12 26-gauge standing seam metal gable roof requires approximately 1,228 sq ft of roofing material (15 roofing squares), while the 4" reinforced monolithic concrete slab w/ grade beam (6" in shop) pours at an estimated 23 cubic yards of 4,000-PSI concrete.

Building costs, foundation specs, egress & CAD customization questions

How much does it cost to build the 40x26 1,040 Sq Ft (26x40) 2 Bed 2 Bath Barndominium Floor Plan with Shop (HG-1512)?

Based on current national residential construction data for barndominium structures, the dried-in structural shell for Plan HG-1512 (1,040 sq ft base footprint) ranges from $32,000 to $41,000 ($32/sq ft baseline). A complete turnkey build—including the 23-yard concrete foundation, 111 linear feet of interior framing, MEP rough-ins for 2 bath(s), and interior finishes across 676 sq ft of heated space plus the 364 sq ft shop bay—ranges from $109,000 to $133,000. Use the interactive Regional Cost Multiplier on this page to adjust for your local labor market and owner-builder sweat equity.

What are the exact room dimensions inside this 676 sq ft 2-bedroom layout?

Plan HG-1512 features 6 architecturally solved spaces inside its 40' × 26' footprint: 1-BAY SHOP / GARAGE (14'-0" × 26'-0", 364 sq ft), PRIMARY SUITE (13'-6" × 11'-6", 155 sq ft), BEDROOM 2 (12'-6" × 11'-6", 144 sq ft), GREAT ROOM & DINING (16'-0" × 14'-6", 232 sq ft), BATH & MUDROOM (10'-0" × 6'-6", 65 sq ft), KITCHEN & ISLAND (10'-0" × 8'-0", 80 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 40' × 26' floor plan be built with post-frame, red-iron steel, or 2x6 stick framing?

Yes. Because the outer envelope is engineered on an even 40'-0" × 26'-0" structural grid (132 LF perimeter) with clear-span 4:12 trusses, a local structural engineer or building kit supplier can adapt the blueprint for Cold-Formed Steel / Post-Frame Clear-Span Trusses (8' o.c.), conventional 2x6 stick framing at 16" o.c., laminated post-frame columns at 8' o.c., or structural insulated panels (SIPs).
