Plan HG-2509 (1,600 Sq Ft (40x40) 2 Bed 2 Bath Barndominium Floor Plan with Shop) is an IRC R304/R310-vetted barndominium blueprint engineered around a 40'-0" × 40'-0" structural grid (1,600 sq ft base footprint, 1:1 Square-Bay Proportion). Configured on the Side-Bay Shop + Wet-Core Mudroom Buffer topology, this layout delivers 1,040 sq ft of conditioned residential living area paired with a 560 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: 2-BAY SHOP / GARAGE (14'-0" × 40'-0", 560 sq ft), PRIMARY SUITE (13'-6" × 17'-6", 236 sq ft), BEDROOM 2 (12'-6" × 17'-6", 219 sq ft), GREAT ROOM & DINING (16'-0" × 22'-6", 360 sq ft), BATH & MUDROOM (10'-0" × 10'-0", 100 sq ft), KITCHEN & ISLAND (10'-0" × 12'-6", 125 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 236 sq ft; BEDROOM 2 at 219 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 160 linear feet of 6" exterior wall framing (~184 framing studs/posts) and 141 linear feet of interior partitions. The 4:12 26-gauge standing seam metal gable roof requires approximately 1,889 sq ft of roofing material (22 roofing squares), while the 4" reinforced monolithic concrete slab w/ grade beam (6" in shop) pours at an estimated 33 cubic yards of 4,000-PSI concrete.

Frequently Asked Questions • Plan HG-2509

Building costs, foundation specs, egress & CAD customization questions

How much does it cost to build the 40x40 1,600 Sq Ft (40x40) 2 Bed 2 Bath Barndominium Floor Plan with Shop (HG-2509)?

Based on current national residential construction data for barndominium structures, the dried-in structural shell for Plan HG-2509 (1,600 sq ft base footprint) ranges from $47,500 to $60,500 ($32/sq ft baseline). A complete turnkey build—including the 33-yard concrete foundation, 141 linear feet of interior framing, MEP rough-ins for 2 bath(s), and interior finishes across 1,040 sq ft of heated space plus the 560 sq ft shop bay—ranges from $164,000 to $200,000. 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 1,040 sq ft 2-bedroom layout?

Plan HG-2509 features 6 architecturally solved spaces inside its 40' × 40' footprint: 2-BAY SHOP / GARAGE (14'-0" × 40'-0", 560 sq ft), PRIMARY SUITE (13'-6" × 17'-6", 236 sq ft), BEDROOM 2 (12'-6" × 17'-6", 219 sq ft), GREAT ROOM & DINING (16'-0" × 22'-6", 360 sq ft), BATH & MUDROOM (10'-0" × 10'-0", 100 sq ft), KITCHEN & ISLAND (10'-0" × 12'-6", 125 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' × 40' 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" × 40'-0" structural grid (160 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).
