Plan HG-2735 (648 Sq Ft (18×36) 2 Bed, 1 Bath Pole Barn Floor Plan with Shop) is an IRC R304/R310-vetted pole barn home (post-frame) blueprint engineered around a 36'-0" × 18'-0" structural grid (648 sq ft base footprint, 0.5:1 Square-Bay Proportion). Configured on the Attached Shop + Mudroom Entry topology, this layout delivers 423 sq ft of conditioned residential living area paired with a 225 sq ft fire-separated workshop/garage bay and 188 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'-6" × 18'-0", 225 sq ft), PRIMARY SUITE (12'-0" × 8'-0", 96 sq ft), BEDROOM 2 (11'-6" × 8'-0", 92 sq ft), GREAT ROOM & DINING (14'-0" × 10'-0", 140 sq ft), BATH & MUDROOM (9'-6" × 4'-6", 43 sq ft), KITCHEN & ISLAND (9'-6" × 5'-6", 52 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 96 sq ft; BEDROOM 2 at 92 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 36' clear-span width utilizes 3-ply laminated post-frame columns (8' o.c.) + bookshelf girts bearing on 108 linear feet of 6" exterior wall framing (~140 framing studs/posts) and 89 linear feet of interior partitions. The 4:12 29-gauge ribbed or 26-gauge standing seam metal roof requires approximately 765 sq ft of roofing material (10 roofing squares), while the concrete pier footings w/ perma-column brackets & floating slab pours at an estimated 16 cubic yards of 4,000-PSI concrete.

Building costs, foundation specs, egress & CAD customization questions

How much does it cost to build the 36x18 648 Sq Ft (18×36) 2 Bed, 1 Bath Pole Barn Floor Plan with Shop (HG-2735)?

Based on current national residential construction data for pole barn home (post-frame) structures, the dried-in structural shell for Plan HG-2735 (648 sq ft base footprint) ranges from $19,000 to $24,500 ($28/sq ft baseline). A complete turnkey build—including the 16-yard concrete foundation, 89 linear feet of interior framing, MEP rough-ins for 1 bath(s), and interior finishes across 423 sq ft of heated space plus the 225 sq ft shop bay—ranges from $64,000 to $77,000. 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 423 sq ft 2-bedroom layout?

Plan HG-2735 features 6 architecturally solved spaces inside its 36' × 18' footprint: 1-BAY SHOP / GARAGE (12'-6" × 18'-0", 225 sq ft), PRIMARY SUITE (12'-0" × 8'-0", 96 sq ft), BEDROOM 2 (11'-6" × 8'-0", 92 sq ft), GREAT ROOM & DINING (14'-0" × 10'-0", 140 sq ft), BATH & MUDROOM (9'-6" × 4'-6", 43 sq ft), KITCHEN & ISLAND (9'-6" × 5'-6", 52 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 36' × 18' floor plan be built with post-frame, red-iron steel, or 2x6 stick framing?

Yes. Because the outer envelope is engineered on an even 36'-0" × 18'-0" structural grid (108 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).
