Plan HG-1553 (840 Sq Ft (28x30) 2 Bed 2 Bath Barndominium Floor Plan with Shop) is an IRC R304/R310-vetted barndominium blueprint engineered around a 30'-0" × 28'-0" structural grid (840 sq ft base footprint, 0.93:1 Square-Bay Proportion). Configured on the Side-Bay Shop + Wet-Core Mudroom Buffer topology, this layout delivers 505 sq ft of conditioned residential living area paired with a 336 sq ft fire-separated workshop/garage bay and 144 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 (12'-0" × 28'-0", 336 sq ft), PRIMARY SUITE (9'-6" × 12'-6", 119 sq ft), BEDROOM 2 (8'-6" × 12'-6", 106 sq ft), GREAT ROOM & DINING (8'-6" × 15'-6", 132 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 119 sq ft; BEDROOM 2 at 106 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 30' clear-span width utilizes cold-formed steel / post-frame clear-span trusses (8' o.c.) bearing on 116 linear feet of 6" exterior wall framing (~147 framing studs/posts) and 102 linear feet of interior partitions. The 4:12 26-gauge standing seam metal gable roof requires approximately 992 sq ft of roofing material (12 roofing squares), while the 4" reinforced monolithic concrete slab w/ grade beam (6" in shop) pours at an estimated 19 cubic yards of 4,000-PSI concrete.

Frequently Asked Questions • Plan HG-1553

Building costs, foundation specs, egress & CAD customization questions

How much does it cost to build the 30x28 840 Sq Ft (28x30) 2 Bed 2 Bath Barndominium Floor Plan with Shop (HG-1553)?

Based on current national residential construction data for barndominium structures, the dried-in structural shell for Plan HG-1553 (840 sq ft base footprint) ranges from $25,500 to $32,500 ($32/sq ft baseline). A complete turnkey build—including the 19-yard concrete foundation, 102 linear feet of interior framing, MEP rough-ins for 2 bath(s), and interior finishes across 505 sq ft of heated space plus the 336 sq ft shop bay—ranges from $84,000 to $102,000. 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 505 sq ft 2-bedroom layout?

Plan HG-1553 features 6 architecturally solved spaces inside its 30' × 28' footprint: 1-BAY SHOP / GARAGE (12'-0" × 28'-0", 336 sq ft), PRIMARY SUITE (9'-6" × 12'-6", 119 sq ft), BEDROOM 2 (8'-6" × 12'-6", 106 sq ft), GREAT ROOM & DINING (8'-6" × 15'-6", 132 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 30' × 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 30'-0" × 28'-0" structural grid (116 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).
