Luxury Barndominium Floor Plans in Idaho

A luxury barndominium is defined by its specification, not its size alone: a vaulted great room with exposed steel or timber, a primary suite that works like a hotel room, a chef's kitchen with a scullery behind it, a proper boot room, and a heated garage or shop for the toys. In Idaho many of these homes go on acreage with a view of the mountains, a river or open farmland, often at the edge of timber or sagebrush. The plan has to earn its finishes by handling winter well and by keeping embers out, because a high-end house on the wildland edge has more to lose.

What actually changes with this feature

The look is the easy part. These are the decisions that follow from it.

A primary suite with its own wing

Luxury plans usually give the primary suite a wing of its own: bedroom, a walk-in closet that connects to the laundry, a bath with a walk-in shower and a soaking tub, and a door to a private covered patio. The code asks for 6 feet 8 inches of ceiling over a showerhead area of at least 30 by 30 inches, which a vaulted bath clears with room to spare.

A boot room worthy of the house

Ski gear, hunting gear, fishing waders, dogs. A luxury plan in Idaho gives the working entry real space: lockers, a bench, a heated floor for drying boots, a dog wash, a half bath and the laundry. Put it between the garage and the kitchen so groceries and gear never cross the great room.

Finishes that do not invite embers

Idaho Firewise recommends Class A roof coverings, with metal among them, enclosed soffits and double-paned tempered glass. The Idaho Department of Lands advises 1/8-inch or smaller metal screens on vents and enclosing or screening the space under decks. On a wooded site, specify ember-resistant vents, noncombustible siding near grade, and a stone or gravel strip right against the house instead of bark mulch.

Mechanical systems for a large, tight house

Idaho requires whole-house mechanical ventilation in every dwelling unit. A large luxury barndominium with a tight envelope usually uses a balanced system with heat recovery, zoned heating for the great room and the bedroom wings, and a mechanical room big enough to service. Plan it as a room, not a closet.

The vaulted great room

Sloped ceilings are measured, even in a showpiece room

The 2018 International Residential Code, which Idaho builds to with its own amendments, sets a 7-foot minimum ceiling height for habitable space. Under a sloped ceiling, the required floor area of the room must have at least 5 feet of height and at least half of it must reach 7 feet. A soaring great room clears that easily, but a primary suite or a reading loft tucked under the low side of a shed roof may not, so check the low eave wherever rooms run to the outside wall.

Common ways to build this

Three common ways to lay this out. Yours does not have to match one exactly — this is a starting point for the conversation, not a catalog.

Great-room luxury ranch

50' x 80' / 3,200 sq ft living / 3 bed + office, 3.5 bath

A vaulted great room and kitchen in the middle, the primary wing at one end, guest suites and an office at the other, a scullery behind the kitchen, and a boot room with a dog wash at the garage entry.

Luxury home with a heated shop

3,000 sq ft living / 2,400 sq ft shop with an RV bay

The house and shop share one roof line, with the shop behind Idaho's 5/8-inch Type X separation. A shop heated for frost protection or intermittent use stays outside the house's energy envelope under Idaho's amendment.

Two-story with a view deck

40' x 60' footprint / 3,600 sq ft on two floors / 4 bed, 4 bath

A main-floor primary suite, guest rooms upstairs, and a covered deck off the great room facing the view. The deck is framed so its underside can be enclosed with metal screen, and a lower deck roof is sized for snow sliding off the main roof.

Ways to build this

This layout can go together several ways. These are the service lines most relevant to it.

Luxury Barndominium: common questions

6 questions worth settling before this plan is drawn. If yours is not on the list, put it in the survey.

Start your project

What makes a barndominium a luxury barndominium?

The specification: vaulted ceilings, custom kitchens, a primary suite with a real bath, high-end windows and doors, heated floors, a large boot room and mechanical systems to match. Square footage helps, but a well-finished 2,400-square-foot plan can be more luxurious than a plain 4,000-square-foot one.

How tall can the great room ceiling be?

As tall as the frame and roof allow. The code sets minimums, not maximums: 7 feet in habitable rooms, and under a sloped ceiling at least half the required floor area at 7 feet with nothing below 5 feet. Very tall rooms need a plan for heat that collects near the ridge and for cleaning high windows.

Do luxury barndominiums in Idaho need fire sprinklers?

No. Idaho Code § 39-4116 exempts single-family homes and two-unit dwellings from any code provision that would require automatic fire sprinklers. Some owners choose them anyway for a large house on a remote site.

How do I protect a high-end barndominium from wildfire?

Follow the Idaho Department of Lands' home protection zones: a noncombustible strip out to about 4 feet, irrigated and mown grass with thinned trees to 30 feet, and managed fuels to 100 feet. Add metal vent screens, enclosed eaves, tempered glass and a metal roof. Idaho Firewise also suggests keeping new construction back from the edges of slopes and draws.

Can a luxury barndominium include a guest suite?

Yes. A guest suite with its own bath and a separate entry is common. If it is meant to be a separate dwelling, that is a zoning question for the county or city planning and zoning office, and it changes the septic design, so decide before the permit set is drawn.

Should the kitchen have a scullery or butler's pantry?

In an open-plan barndominium it is the best way to keep a showpiece kitchen clean: prep, dishes, small appliances and a second sink go in a room behind the main kitchen. Put it next to the boot room and garage door so groceries go straight in.
