Plan HG-1278 (881 Sq Ft (22x40) 2 Bed 2 Bath Modern Cabin Floor Plan) is an IRC R304/R310-vetted modern cabin blueprint engineered around a 40'-0" × 22'-0" structural grid (880 sq ft base footprint, 0.55:1 Square-Bay Proportion). Configured on the Consolidated Wet-Wall + Open Great Room topology, this layout delivers 881 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" × 10'-0", 210 sq ft), BEDROOM 2 (19'-0" × 10'-0", 190 sq ft), GREAT ROOM & DINING (25'-0" × 12'-0", 300 sq ft), BATH & LAUNDRY (15'-0" × 5'-6", 83 sq ft), KITCHEN & ISLAND (15'-0" × 6'-6", 98 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 210 sq ft; BEDROOM 2 at 190 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 2x6 advanced framing w/ steel moment frame view wall bearing on 124 linear feet of 6" exterior wall framing (~141 framing studs/posts) and 100 linear feet of interior partitions. The 2.5:12 single-slope shed metal roof w/ deep cantilevered overhangs requires approximately 1,007 sq ft of roofing material (13 roofing squares), while the insulated concrete slab w/ radiant floor heating prep pours at an estimated 18 cubic yards of 4,000-PSI concrete.

Frequently Asked Questions • Plan HG-1278

Building costs, foundation specs, egress & CAD customization questions

How much does it cost to build the 40x22 881 Sq Ft (22x40) 2 Bed 2 Bath Modern Cabin Floor Plan (HG-1278)?

Based on current national residential construction data for modern cabin structures, the dried-in structural shell for Plan HG-1278 (880 sq ft base footprint) ranges from $39,500 to $50,500 ($46/sq ft baseline). A complete turnkey build—including the 18-yard concrete foundation, 100 linear feet of interior framing, MEP rough-ins for 2 bath(s), and interior finishes across 881 sq ft of heated space—ranges from $153,000 to $186,000. 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 881 sq ft 2-bedroom layout?

Plan HG-1278 features 5 architecturally solved spaces inside its 40' × 22' footprint: PRIMARY SUITE (21'-0" × 10'-0", 210 sq ft), BEDROOM 2 (19'-0" × 10'-0", 190 sq ft), GREAT ROOM & DINING (25'-0" × 12'-0", 300 sq ft), BATH & LAUNDRY (15'-0" × 5'-6", 83 sq ft), KITCHEN & ISLAND (15'-0" × 6'-6", 98 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' × 22' 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" × 22'-0" structural grid (124 LF perimeter) with clear-span 2.5:12 trusses, a local structural engineer or building kit supplier can adapt the blueprint for 2x6 Advanced Framing w/ Steel Moment Frame View Wall, conventional 2x6 stick framing at 16" o.c., laminated post-frame columns at 8' o.c., or structural insulated panels (SIPs).
