HB-40510 H-Shaped Barndominium Plan: Two 2-Car Garages Built Into The Wings
4,000–4,999 sq ft · 4 bed / 4.5 bath · 1 story · Two 2-car garages
PDF plan set $1,349.99 · Five printed sets $1,599.99

Most H plans leave the garage for later. HB-40510 builds in two of them: a two-car garage flanking the entrance at each wing, which makes it the plan to look at if you need room for four vehicles, or two vehicles and a shop.
Layout
- Center: A central living room linking the private wing and the utility wing.
- Garages: Twin two-car garages flanking the main entrance.
- Bedrooms: A game and media room beside the secondary bedrooms; the primary suite in a rear corner with a large bath and walk-in closet.
- Outdoors: Covered porches along both side wings.

Who It Suits
Households with more vehicles than most H plans can park, or anyone who wants one garage bay to double as a workshop.

What It Costs To Build
At a standard finish of $80–$120 per square foot of heated space, 4,000–4,999 sq ft comes to about $320,000 – $599,880. A high-end finish at $150 or more per square foot starts around $600,000. Land, site work, septic and utilities are extra, and porches price closer to shell rates.
An H has much more exterior wall than a rectangle of the same size, so plan toward the top of the range. How the H shape affects cost.
Lot Width Needed
The overall footprint for this plan is shown on the floor plan drawing. Add your county's side setbacks to both sides of that width; on rural parcels they commonly run 10 to 25 feet a side.
