Plan HG-2312 (1,296 Sq Ft (36x36) 3 Bed 2 Bath Barndominium Floor Plan with Shop (Pull-Through Shop + Split Living Core)) is an IRC R304/R310-vetted barndominium blueprint engineered around a 36'-0" × 36'-0" structural grid (1,296 sq ft base footprint, 1:1 Square-Bay Proportion). Configured on the Pull-Through Shop + Split Living Core topology, this layout delivers 811 sq ft of conditioned residential living area paired with a 486 sq ft fire-separated workshop/garage bay and 180 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 (13'-6" × 36'-0", 486 sq ft), PRIMARY SUITE (11'-6" × 16'-0", 184 sq ft), BEDROOM 2 (11'-0" × 16'-0", 176 sq ft), GREAT ROOM & DINING (13'-0" × 20'-0", 260 sq ft), BATH & MUDROOM (9'-6" × 9'-0", 86 sq ft), KITCHEN & ISLAND (9'-6" × 11'-0", 105 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 184 sq ft; BEDROOM 2 at 176 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 36' clear-span width utilizes cold-formed steel / post-frame clear-span trusses (8' o.c.) bearing on 144 linear feet of 6" exterior wall framing (~174 framing studs/posts) and 127 linear feet of interior partitions. The 4:12 26-gauge standing seam metal gable roof requires approximately 1,530 sq ft of roofing material (18 roofing squares), while the 4" reinforced monolithic concrete slab w/ grade beam (6" in shop) pours at an estimated 27 cubic yards of 4,000-PSI concrete.

How much does it cost to build the 36x36 1,296 Sq Ft (36x36) 3 Bed 2 Bath Barndominium Floor Plan with Shop (Pull-Through Shop + Split Living Core) (HG-2312)?

Based on current national residential construction data for barndominium structures, the dried-in structural shell for Plan HG-2312 (1,296 sq ft base footprint) ranges from $38,500 to $49,000 ($32/sq ft baseline). A complete turnkey build—including the 27-yard concrete foundation, 127 linear feet of interior framing, MEP rough-ins for 2 bath(s), and interior finishes across 811 sq ft of heated space plus the 486 sq ft shop bay—ranges from $131,000 to $159,000. 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 811 sq ft 3-bedroom layout?

Plan HG-2312 features 6 architecturally solved spaces inside its 36' × 36' footprint: 1-BAY SHOP / GARAGE (13'-6" × 36'-0", 486 sq ft), PRIMARY SUITE (11'-6" × 16'-0", 184 sq ft), BEDROOM 2 (11'-0" × 16'-0", 176 sq ft), GREAT ROOM & DINING (13'-0" × 20'-0", 260 sq ft), BATH & MUDROOM (9'-6" × 9'-0", 86 sq ft), KITCHEN & ISLAND (9'-6" × 11'-0", 105 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 36' × 36' floor plan be built with post-frame, red-iron steel, or 2x6 stick framing?

Yes. Because the outer envelope is engineered on an even 36'-0" × 36'-0" structural grid (144 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).
