Plan HG-2677 (3,500 Sq Ft (50×70) 2 Bed, 2 Bath Barndo Floor Plan with Shop) is an IRC R304/R310-vetted barndominium blueprint engineered around a 70'-0" × 50'-0" structural grid (3,500 sq ft base footprint, 0.71:1 Square-Bay Proportion). Configured on the Attached Shop + Mudroom Entry topology, this layout delivers 2,275 sq ft of conditioned residential living area paired with a 1,225 sq ft fire-separated workshop/garage bay and 364 sq ft of covered outdoor porch deck.

Inside the conditioned envelope, the floor plan is organized into 6 distinct architectural zones: 2-BAY SHOP / GARAGE (24'-6" × 50'-0", 1225 sq ft), PRIMARY SUITE (23'-6" × 22'-0", 517 sq ft), BEDROOM 2 (22'-0" × 22'-0", 484 sq ft), GREAT ROOM & DINING (28'-0" × 28'-0", 784 sq ft), BATH & MUDROOM (17'-6" × 12'-6", 219 sq ft), KITCHEN & ISLAND (17'-6" × 15'-6", 271 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 517 sq ft; BEDROOM 2 at 484 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 70' 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 (~252 framing studs/posts) and 204 linear feet of interior partitions. The 4:12 26-gauge standing seam metal gable roof requires approximately 4,132 sq ft of roofing material (46 roofing squares), while the 4" reinforced monolithic concrete slab w/ grade beam (6" in shop) pours at an estimated 65 cubic yards of 4,000-PSI concrete.

How much does it cost to build the 70x50 3,500 Sq Ft (50×70) 2 Bed, 2 Bath Barndo Floor Plan with Shop (HG-2677)?

Based on current national residential construction data for barndominium structures, the dried-in structural shell for Plan HG-2677 (3,500 sq ft base footprint) ranges from $102,000 to $130,000 ($32/sq ft baseline). A complete turnkey build—including the 65-yard concrete foundation, 204 linear feet of interior framing, MEP rough-ins for 2 bath(s), and interior finishes across 2,275 sq ft of heated space plus the 1,225 sq ft shop bay—ranges from $356,000 to $433,000. 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 2,275 sq ft 2-bedroom layout?

Plan HG-2677 features 6 architecturally solved spaces inside its 70' × 50' footprint: 2-BAY SHOP / GARAGE (24'-6" × 50'-0", 1225 sq ft), PRIMARY SUITE (23'-6" × 22'-0", 517 sq ft), BEDROOM 2 (22'-0" × 22'-0", 484 sq ft), GREAT ROOM & DINING (28'-0" × 28'-0", 784 sq ft), BATH & MUDROOM (17'-6" × 12'-6", 219 sq ft), KITCHEN & ISLAND (17'-6" × 15'-6", 271 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 70' × 50' floor plan be built with post-frame, red-iron steel, or 2x6 stick framing?

Yes. Because the outer envelope is engineered on an even 70'-0" × 50'-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).
