Plan HG-1204 (800 Sq Ft (20x40) 2 Bed 2 Bath Pole Barn Home (Post-Frame) Floor Plan with Shop (Pull-Through Shop + Split Living Core)) 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 Pull-Through Shop + Split Living Core topology, this layout delivers 501 sq ft of conditioned residential living area paired with a 300 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" × 20'-0", 300 sq ft), PRIMARY SUITE (13'-0" × 9'-0", 117 sq ft), BEDROOM 2 (12'-0" × 9'-0", 108 sq ft), GREAT ROOM & DINING (15'-6" × 11'-0", 171 sq ft), BATH & MUDROOM (9'-6" × 5'-0", 48 sq ft), KITCHEN & ISLAND (9'-6" × 6'-0", 57 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 117 sq ft; BEDROOM 2 at 108 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 (~154 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 19 cubic yards of 4,000-PSI concrete.

How much does it cost to build the 40x20 800 Sq Ft (20x40) 2 Bed 2 Bath Pole Barn Home (Post-Frame) Floor Plan with Shop (Pull-Through Shop + Split Living Core) (HG-1204)?

Based on current national residential construction data for pole barn home (post-frame) structures, the dried-in structural shell for Plan HG-1204 (800 sq ft base footprint) ranges from $23,000 to $29,000 ($28/sq ft baseline).

What are the exact room dimensions inside this 501 sq ft 2-bedroom layout?

Plan HG-1204 features 6 architecturally solved spaces inside its 40' × 20' footprint: 1-BAY SHOP / GARAGE (15'-0" × 20'-0", 300 sq ft), PRIMARY SUITE (13'-0" × 9'-0", 117 sq ft), BEDROOM 2 (12'-0" × 9'-0", 108 sq ft), GREAT ROOM & DINING (15'-6" × 11'-0", 171 sq ft), BATH & MUDROOM (9'-6" × 5'-0", 48 sq ft), KITCHEN & ISLAND (9'-6" × 6'-0", 57 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).
