Plan HG-2776 (800 Sq Ft (20×40) 2 Bed, 2 Bath Pole Barn Floor Plan) is an IRC R304/R310-vetted pole barn home (post-frame) blueprint engineered around a 40'-0" × 20'-0" structural grid (800 sq ft base footprint, 0.5:1 Square-Bay Proportion). Configured on the Open-Concept Great Room topology, this layout delivers 800 sq ft of conditioned residential living area and 150 sq ft of covered outdoor porch deck.

Inside the conditioned envelope, the floor plan is organized into 5 distinct architectural zones: PRIMARY SUITE (21'-0" × 9'-0", 189 sq ft), BEDROOM 2 (19'-0" × 9'-0", 171 sq ft), GREAT ROOM & DINING (25'-0" × 11'-0", 275 sq ft), BATH & LAUNDRY (15'-0" × 5'-0", 75 sq ft), KITCHEN & ISLAND (15'-0" × 6'-0", 90 sq ft). Plumbing rough-ins are consolidated across BATH & LAUNDRY, KITCHEN & ISLAND to minimize sub-slab trenching and manifold pipe runs. Sleeping quarters (PRIMARY SUITE at 189 sq ft; BEDROOM 2 at 171 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 3-ply laminated post-frame columns (8' o.c.) + bookshelf girts bearing on 120 linear feet of 6" exterior wall framing (~138 framing studs/posts) and 97 linear feet of interior partitions. The 4:12 29-gauge ribbed or 26-gauge standing seam metal roof requires approximately 944 sq ft of roofing material (12 roofing squares), while the concrete pier footings w/ perma-column brackets & floating slab pours at an estimated 17 cubic yards of 4,000-PSI concrete.

Frequently Asked Questions • Plan HG-2776

Building costs, foundation specs, egress & CAD customization questions

How much does it cost to build the 40x20 800 Sq Ft (20×40) 2 Bed, 2 Bath Pole Barn Floor Plan (HG-2776)?

Based on current national residential construction data for pole barn home (post-frame) structures, the dried-in structural shell for Plan HG-2776 (800 sq ft base footprint) ranges from $23,000 to $29,500 ($28/sq ft baseline). A complete turnkey build—including the 17-yard concrete foundation, 97 linear feet of interior framing, MEP rough-ins for 2 bath(s), and interior finishes across 800 sq ft of heated space—ranges from $97,000 to $117,000. 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 800 sq ft 2-bedroom layout?

Plan HG-2776 features 5 architecturally solved spaces inside its 40' × 20' footprint: PRIMARY SUITE (21'-0" × 9'-0", 189 sq ft), BEDROOM 2 (19'-0" × 9'-0", 171 sq ft), GREAT ROOM & DINING (25'-0" × 11'-0", 275 sq ft), BATH & LAUNDRY (15'-0" × 5'-0", 75 sq ft), KITCHEN & ISLAND (15'-0" × 6'-0", 90 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' × 20' 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" × 20'-0" structural grid (120 LF perimeter) with clear-span 4:12 trusses, a local structural engineer or building kit supplier can adapt the blueprint for 3-Ply Laminated Post-Frame Columns (8' o.c.) + Bookshelf Girts, conventional 2x6 stick framing at 16" o.c., laminated post-frame columns at 8' o.c., or structural insulated panels (SIPs).
