Plan HG-2420 (1,728 Sq Ft (36x48) 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 48'-0" × 36'-0" structural grid (1,728 sq ft base footprint, 0.75:1 Square-Bay Proportion). Configured on the Pull-Through Shop + Split Living Core topology, this layout delivers 1,081 sq ft of conditioned residential living area paired with a 648 sq ft fire-separated workshop/garage bay and 240 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 (18'-0" × 36'-0", 648 sq ft), PRIMARY SUITE (11'-6" × 16'-0", 184 sq ft), BEDROOM 2 (9'-6" × 16'-0", 152 sq ft), BEDROOM 3 (9'-0" × 16'-0", 144 sq ft), GREAT ROOM & DINING (18'-6" × 20'-0", 370 sq ft), BATH & MUDROOM (11'-6" × 9'-0", 104 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 152 sq ft; BEDROOM 3 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 48' clear-span width utilizes cold-formed steel / post-frame clear-span trusses (8' o.c.) bearing on 168 linear feet of 6" exterior wall framing (~203 framing studs/posts) and 154 linear feet of interior partitions. The 4:12 26-gauge standing seam metal gable roof requires approximately 2,040 sq ft of roofing material (24 roofing squares), while the 4" reinforced monolithic concrete slab w/ grade beam (6" in shop) pours at an estimated 35 cubic yards of 4,000-PSI concrete.

What are the exact room dimensions inside this 1,081 sq ft 3-bedroom layout?

Plan HG-2420 features 7 architecturally solved spaces inside its 48' × 36' footprint: 2-BAY SHOP / GARAGE (18'-0" × 36'-0", 648 sq ft), PRIMARY SUITE (11'-6" × 16'-0", 184 sq ft), BEDROOM 2 (9'-6" × 16'-0", 152 sq ft), BEDROOM 3 (9'-0" × 16'-0", 144 sq ft), GREAT ROOM & DINING (18'-6" × 20'-0", 370 sq ft), BATH & MUDROOM (11'-6" × 9'-0", 104 sq ft), KITCHEN & ISLAND (11'-6" × 11'-0", 127 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 48' × 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 48'-0" × 36'-0" structural grid (168 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).
