Plan HG-2672 (3,200 Sq Ft (40x80) 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 80'-0" × 40'-0" structural grid (3,200 sq ft base footprint, 0.5:1 Square-Bay Proportion). Configured on the Pull-Through Shop + Split Living Core topology, this layout delivers 1,981 sq ft of conditioned residential living area paired with a 1,220 sq ft fire-separated workshop/garage bay and 396 sq ft of covered outdoor porch deck.

Inside the conditioned envelope, the floor plan is organized into 7 distinct architectural zones: 2-BAY SHOP / GARAGE (30'-6" × 40'-0", 1220 sq ft), PRIMARY SUITE (19'-0" × 17'-6", 333 sq ft), BEDROOM 2 (15'-6" × 17'-6", 271 sq ft), BEDROOM 3 (15'-0" × 17'-6", 263 sq ft), GREAT ROOM & DINING (30'-6" × 22'-6", 686 sq ft), BATH & MUDROOM (19'-0" × 10'-0", 190 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 333 sq ft; BEDROOM 2 at 271 sq ft; BEDROOM 3 at 263 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 80' clear-span width utilizes cold-formed steel / post-frame clear-span trusses (8' o.c.) bearing on 240 linear feet of 6" exterior wall framing (~264 framing studs/posts) and 206 linear feet of interior partitions. The 4:12 26-gauge standing seam metal gable roof requires approximately 3,778 sq ft of roofing material (43 roofing squares), while the 4" reinforced monolithic concrete slab w/ grade beam (6" in shop) pours at an estimated 61 cubic yards of 4,000-PSI concrete.

What are the exact room dimensions inside this 1,981 sq ft 3-bedroom layout?

Plan HG-2672 features 7 architecturally solved spaces inside its 80' × 40' footprint: 2-BAY SHOP / GARAGE (30'-6" × 40'-0", 1220 sq ft), PRIMARY SUITE (19'-0" × 17'-6", 333 sq ft), BEDROOM 2 (15'-6" × 17'-6", 271 sq ft), BEDROOM 3 (15'-0" × 17'-6", 263 sq ft), GREAT ROOM & DINING (30'-6" × 22'-6", 686 sq ft), BATH & MUDROOM (19'-0" × 10'-0", 190 sq ft), KITCHEN & ISLAND (19'-0" × 12'-6", 238 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 80' × 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 80'-0" × 40'-0" structural grid (240 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).
