Plan HG-1550 (1,040 Sq Ft (26x40) 3 Bed 2 Bath Garage with Loft / Apartment Above Floor Plan with Apartment Above) is an IRC R304/R310-vetted garage with loft / apartment above blueprint engineered around a 40'-0" × 26'-0" structural grid (1,040 sq ft base footprint, 0.65:1 Square-Bay Proportion). Configured on the Side-Vestibule Garage + Balcony Apartment topology, this layout delivers 1,300 sq ft of conditioned residential living area paired with a 780 sq ft fire-separated workshop/garage bay and 105 sq ft of covered outdoor porch deck.
Inside the conditioned envelope, the floor plan is organized into 9 distinct architectural zones: 1-BAY GARAGE (30'-0" × 26'-0", 780 sq ft), UTILITY & GEAR (10'-0" × 11'-6", 115 sq ft), FOYER & STAIRS (10'-0" × 14'-6", 145 sq ft), PRIMARY SUITE (16'-0" × 12'-0", 192 sq ft), BEDROOM 2 (14'-0" × 12'-0", 168 sq ft), FULL BATH (10'-0" × 12'-0", 120 sq ft). Plumbing rough-ins are consolidated across UTILITY & GEAR, FULL BATH, KITCHEN & ISLAND to minimize sub-slab trenching and manifold pipe runs. Sleeping quarters (PRIMARY SUITE at 192 sq ft; BEDROOM 2 at 168 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 lower walls + 14" engineered wood i-joist floor system bearing on 132 linear feet of 6" exterior wall framing (~180 framing studs/posts) and 187 linear feet of interior partitions. The 8:12 dormered gable or gambrel roof (8:12 / 4:12 shed dormers) requires approximately 1,400 sq ft of roofing material (14 roofing squares), while the 6" reinforced garage slab w/ perimeter footings & apron pours at an estimated 25 cubic yards of 4,000-PSI concrete.
Building costs, foundation specs, egress & CAD customization questions
Based on current national residential construction data for garage with loft / apartment above structures, the dried-in structural shell for Plan HG-1550 (1,040 sq ft base footprint) ranges from $66,500 to $85,000 ($38/sq ft baseline). A complete turnkey build—including the 25-yard concrete foundation, 187 linear feet of interior framing, MEP rough-ins for 2 bath(s), and interior finishes across 1,300 sq ft of heated space plus the 780 sq ft shop bay—ranges from $214,000 to $261,000.

Plan HG-1550 features 9 architecturally solved spaces inside its 40' × 26' footprint: 1-BAY GARAGE (30'-0" × 26'-0", 780 sq ft), UTILITY & GEAR (10'-0" × 11'-6", 115 sq ft), FOYER & STAIRS (10'-0" × 14'-6", 145 sq ft), PRIMARY SUITE (16'-0" × 12'-0", 192 sq ft), BEDROOM 2 (14'-0" × 12'-0", 168 sq ft), FULL BATH (10'-0" × 12'-0", 120 sq ft), LIVING & DINING (17'-6" × 14'-0", 245 sq ft), KITCHEN & ISLAND (12'-6" × 14'-0", 175 sq ft), STAIR LANDING (10'-0" × 14'-0", 140 sq ft). Every habitable room meets or exceeds IRC R304 minimum area (70+ sq ft) and minimum horizontal dimension (7'-0"+) requirements.
Yes. Because the outer envelope is engineered on an even 40'-0" × 26'-0" structural grid (132 LF perimeter) with clear-span 8:12 trusses, a local structural engineer or building kit supplier can adapt the blueprint for 2x6 Lower Walls + 14" Engineered Wood I-Joist Floor System, conventional 2x6 stick framing at 16" o.c., laminated post-frame columns at 8' o.c., or structural insulated panels (SIPs).
Downloading Plan HG-1550 provides the high-resolution scalable vector floor plan (.SVG) with crisp architectural lineweights, exterior dimension strings (40'-0" × 26'-0"), room-by-room callouts, door swing arcs, and window schedules, plus instant browser printing for contractor bidding and preliminary municipal zoning review.
