Plan HG-2854 (720 Sq Ft (24×30) 1 Bed, 1 Bath Barndo Floor Plan with Shop) is an IRC R304/R310-vetted barndominium blueprint engineered around a 30'-0" × 24'-0" structural grid (720 sq ft base footprint, 0.8:1 Square-Bay Proportion). Configured on the Attached Shop + Mudroom Entry topology, this layout delivers 432 sq ft of conditioned residential living area paired with a 288 sq ft fire-separated workshop/garage bay and 144 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'-0" × 24'-0", 288 sq ft), PRIMARY SUITE (11'-6" × 10'-6", 121 sq ft), WALK-IN CLOSET (6'-6" × 10'-6", 68 sq ft), GREAT ROOM & DINING (8'-6" × 13'-6", 115 sq ft), BATH & MUDROOM (9'-6" × 6'-0", 57 sq ft), KITCHEN & ISLAND (9'-6" × 7'-6", 71 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 121 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 30' clear-span width utilizes cold-formed steel / post-frame clear-span trusses (8' o.c.) bearing on 108 linear feet of 6" exterior wall framing (~136 framing studs/posts) and 93 linear feet of interior partitions. The 4:12 26-gauge standing seam metal gable roof requires approximately 850 sq ft of roofing material (11 roofing squares), while the 4" reinforced monolithic concrete slab w/ grade beam (6" in shop) pours at an estimated 17 cubic yards of 4,000-PSI concrete.

Frequently Asked Questions • Plan HG-2854

Building costs, foundation specs, egress & CAD customization questions

How much does it cost to build the 30x24 720 Sq Ft (24×30) 1 Bed, 1 Bath Barndo Floor Plan with Shop (HG-2854)?

Based on current national residential construction data for barndominium structures, the dried-in structural shell for Plan HG-2854 (720 sq ft base footprint) ranges from $22,000 to $28,500 ($32/sq ft baseline). A complete turnkey build—including the 17-yard concrete foundation, 93 linear feet of interior framing, MEP rough-ins for 1 bath(s), and interior finishes across 432 sq ft of heated space plus the 288 sq ft shop bay—ranges from $73,000 to $88,000. 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 432 sq ft 1-bedroom layout?

Plan HG-2854 features 6 architecturally solved spaces inside its 30' × 24' footprint: 1-BAY SHOP / GARAGE (12'-0" × 24'-0", 288 sq ft), PRIMARY SUITE (11'-6" × 10'-6", 121 sq ft), WALK-IN CLOSET (6'-6" × 10'-6", 68 sq ft), GREAT ROOM & DINING (8'-6" × 13'-6", 115 sq ft), BATH & MUDROOM (9'-6" × 6'-0", 57 sq ft), KITCHEN & ISLAND (9'-6" × 7'-6", 71 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.

Can this 30' × 24' floor plan be built with post-frame, red-iron steel, or 2x6 stick framing?

Yes. Because the outer envelope is engineered on an even 30'-0" × 24'-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 Cold-Formed Steel / Post-Frame Clear-Span Trusses (8' o.c.), conventional 2x6 stick framing at 16" o.c., laminated post-frame columns at 8' o.c., or structural insulated panels (SIPs).

What files are included in the free CAD blueprint download for Plan HG-2854?

Downloading Plan HG-2854 provides the high-resolution scalable vector floor plan (.SVG) with crisp architectural lineweights, exterior dimension strings (30'-0" × 24'-0"), room-by-room callouts, door swing arcs, and window schedules, plus instant browser printing for contractor bidding and preliminary municipal zoning review.
