Plan HG-1633 (1,120 Sq Ft (28x40) 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 40'-0" × 28'-0" structural grid (1,120 sq ft base footprint, 0.7:1 Square-Bay Proportion). Configured on the Pull-Through Shop + Split Living Core topology, this layout delivers 701 sq ft of conditioned residential living area paired with a 420 sq ft fire-separated workshop/garage bay and 200 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 (15'-0" × 28'-0", 420 sq ft), PRIMARY SUITE (13'-0" × 12'-6", 163 sq ft), BEDROOM 2 (12'-0" × 12'-6", 150 sq ft), GREAT ROOM & DINING (15'-6" × 15'-6", 240 sq ft), BATH & MUDROOM (9'-6" × 7'-0", 67 sq ft), KITCHEN & ISLAND (9'-6" × 8'-6", 81 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 163 sq ft; BEDROOM 2 at 150 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 136 linear feet of 6" exterior wall framing (~168 framing studs/posts) and 114 linear feet of interior partitions. The 4:12 26-gauge standing seam metal gable roof requires approximately 1,322 sq ft of roofing material (16 roofing squares), while the 4" reinforced monolithic concrete slab w/ grade beam (6" in shop) pours at an estimated 24 cubic yards of 4,000-PSI concrete.

How much does it cost to build the 40x28 1,120 Sq Ft (28x40) 3 Bed 2 Bath Barndominium Floor Plan with Shop (Pull-Through Shop + Split Living Core) (HG-1633)?
Based on current national residential construction data for barndominium structures, the dried-in structural shell for Plan HG-1633 (1,120 sq ft base footprint) ranges from $34,000 to $43,500 ($32/sq ft baseline). A complete turnkey build—including the 24-yard concrete foundation, 114 linear feet of interior framing, MEP rough-ins for 2 bath(s), and interior finishes across 701 sq ft of heated space plus the 420 sq ft shop bay—ranges from $115,000 to $139,000.

What are the exact room dimensions inside this 701 sq ft 3-bedroom layout?
Plan HG-1633 features 6 architecturally solved spaces inside its 40' × 28' footprint: 1-BAY SHOP / GARAGE (15'-0" × 28'-0", 420 sq ft), PRIMARY SUITE (13'-0" × 12'-6", 163 sq ft), BEDROOM 2 (12'-0" × 12'-6", 150 sq ft), GREAT ROOM & DINING (15'-6" × 15'-6", 240 sq ft), BATH & MUDROOM (9'-6" × 7'-0", 67 sq ft), KITCHEN & ISLAND (9'-6" × 8'-6", 81 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' × 28' 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" × 28'-0" structural grid (136 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).
