Plan HG-2475 (2,600 Sq Ft (36x50) 3 Bed 2 Bath A-Frame Cabin Floor Plan with Loft) is an IRC R304/R310-vetted a-frame cabin blueprint engineered around a 50'-0" × 36'-0" structural grid (1,800 sq ft base footprint, 0.72:1 Square-Bay Proportion). Configured on the Cathedral Glass Gable + Overlooking Sleeping Loft topology, this layout delivers 2,600 sq ft of conditioned residential living area and 400 sq ft of covered outdoor porch deck.

Inside the conditioned envelope, the floor plan is organized into 6 distinct architectural zones: MAIN BEDROOM (29'-0" × 16'-0", 464 sq ft), FULL BATH (21'-0" × 16'-0", 336 sq ft), CATHEDRAL GREAT ROOM (29'-0" × 20'-0", 580 sq ft), KITCHEN & DINING (21'-0" × 20'-0", 420 sq ft), UPPER SLEEPING LOFT (50'-0" × 16'-0", 800 sq ft), OPEN TO BELOW (50'-0" × 20'-0", 1000 sq ft). Plumbing rough-ins are consolidated across FULL BATH, KITCHEN & DINING to minimize sub-slab trenching and manifold pipe runs. Sleeping quarters (MAIN BEDROOM at 464 sq ft; UPPER SLEEPING LOFT at 800 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 50' clear-span width utilizes heavy timber / engineered glulam a-truss system (4' o.c.) bearing on 172 linear feet of 6" exterior wall framing (~174 framing studs/posts) and 222 linear feet of interior partitions. The 12:12 continuous steep-pitch standing seam metal roof (60°) requires approximately 2,851 sq ft of roofing material (39 roofing squares), while the insulated concrete pier / frost-protected slab or full walkout pours at an estimated 32 cubic yards of 4,000-PSI concrete.

Frequently Asked Questions • Plan HG-2475

Building costs, foundation specs, egress & CAD customization questions

How much does it cost to build the 50x36 2,600 Sq Ft (36x50) 3 Bed 2 Bath A-Frame Cabin Floor Plan with Loft (HG-2475)?

Based on current national residential construction data for a-frame cabin structures, the dried-in structural shell for Plan HG-2475 (1,800 sq ft base footprint) ranges from $113,000 to $144,500 ($45/sq ft baseline). A complete turnkey build—including the 32-yard concrete foundation, 222 linear feet of interior framing, MEP rough-ins for 2 bath(s), and interior finishes across 2,600 sq ft of heated space—ranges from $433,000 to $527,000. 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 2,600 sq ft 3-bedroom layout?

Plan HG-2475 features 6 architecturally solved spaces inside its 50' × 36' footprint: MAIN BEDROOM (29'-0" × 16'-0", 464 sq ft), FULL BATH (21'-0" × 16'-0", 336 sq ft), CATHEDRAL GREAT ROOM (29'-0" × 20'-0", 580 sq ft), KITCHEN & DINING (21'-0" × 20'-0", 420 sq ft), UPPER SLEEPING LOFT (50'-0" × 16'-0", 800 sq ft), OPEN TO BELOW (50'-0" × 20'-0", 1000 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 50' × 36' floor plan be built with post-frame, red-iron steel, or 2x6 stick framing?

Yes. Because the outer envelope is engineered on an even 50'-0" × 36'-0" structural grid (172 LF perimeter) with clear-span 12:12 trusses, a local structural engineer or building kit supplier can adapt the blueprint for Heavy Timber / Engineered Glulam A-Truss System (4' o.c.), conventional 2x6 stick framing at 16" o.c., laminated post-frame columns at 8' o.c., or structural insulated panels (SIPs).
