Luxury Barndominium Floor Plans in Michigan

A luxury barndominium is defined by its specification, not by the steel. Larger footprints, taller sidewalls, vaulted great rooms with a wall of glass toward the view, a primary suite in its own wing, a finished basement, radiant floors, a heated shop and a covered outdoor kitchen are what move a barndominium from a practical building to a finished home. In Michigan each of those choices also brings a question: more roof means more snow to carry, more glass means more heat to keep in, and more bedrooms and baths mean a larger septic system where there is no sewer.

What actually changes with this feature

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

Clear-span great rooms

A post-frame or steel frame can span a great room without interior columns, which is where the open, vaulted barndominium look comes from. The wider the span and the heavier the snow load for your site, the deeper the trusses, so the same 40-foot room is drawn differently where the code's snow table is high.

Glass and the energy code

A wall of windows toward a lake or a field is the signature of many luxury plans. The energy provisions of the Michigan Residential Code set the window and insulation performance for the edition in force when you apply, and large glass areas are often met with higher-performance windows or extra insulation elsewhere. Plan the glass and the insulation together.

A finished basement adds a floor

Many luxury plans put a family room, a guest suite, a gym or a theatre in a finished basement or walkout. It uses the depth the foundation already needs for frost, but every basement bedroom needs its own emergency escape opening, and radon-resistant features under the slab and a radon test before finishing are worth planning in, as the U.S. Environmental Protection Agency describes for new homes.

Heated shop and garage

A luxury barndominium often includes a heated shop with a tall overhead door for a boat, a camper or equipment, a floor drain, and in-floor heat. An attached shop needs the separation the code requires between a garage and the dwelling, and a larger building may raise questions under the township zoning ordinance about accessory uses and building height.

Big rooms, big roofs

A luxury plan in Michigan is also a snow plan

The features that make a barndominium feel luxurious, a clear-span great room, a tall ceiling, a long covered porch, a taller roof over the living block beside a lower roof over the garage, are the same features that decide how snow sits on the building. Where a lower roof meets a taller wall, wind drifts snow onto the lower roof, and lake-effect storms can add heavy snow in narrow bands in a few hours. The roof carries the ground snow load the Michigan Residential Code's snow table sets for your county or township, and the truss design has to account for drifts at every step in the roofline. Draw the rooflines first and the interior second.

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 plan with a primary wing

50' x 80' / 3,000 sq ft living / 4 bed, 3.5 bath / 3-car garage

A vaulted great room and kitchen in the center under the tallest roof, the primary suite in its own wing with a walk-in closet and a tiled shower, and three more bedrooms on the other side. The garage steps down under a lower roof, drawn for the drift that step creates.

Lake or view house over a walkout

40' x 70' main / 2,800 sq ft + finished walkout below

The main floor faces the view with a wall of glass and a covered deck, and the walkout below holds a family room, a guest suite, a bar and a mechanical room. On a shoreline lot, EGLE regulates many wetlands and building in a designated critical dune area needs a permit, so check before the plan is final.

Estate shouse

2,400 sq ft living / 2,000 sq ft heated shop / one roofline

A finished home and a full heated shop under one long roof, with a tall door for a motorhome or boat, a wash bay with a floor drain, and a mudroom and half bath between the shop and the kitchen.

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 finish level and the features: larger and taller rooms, a wall of glass toward the view, a primary suite in its own wing, custom kitchen and baths, radiant floors, a finished basement and a heated shop. The structure underneath is the same kind of frame as any barndominium.

Does a large barndominium need a sealed set of plans in Michigan?

It depends on the living area. Michigan law lets plans for a detached one- or two-family home with up to 3,500 square feet of living area, measured as calculated floor area, be prepared without an architect's or engineer's seal. That figure counts habitable space measured to the outside of the exterior walls, and does not include a basement, an attic, a garage or an open porch. Above that line, the plans need a licensed architect or engineer. A shop or garage bay is not habitable space, so a large shouse can stay under it.

Can a barndominium have a finished basement in Michigan?

Yes. A barndominium can sit on a basement like any home. The basement walls carry the frame above, and each basement bedroom needs an emergency escape opening.

Do large roofs need special snow design in Michigan?

Every roof is designed for the ground snow load the Michigan Residential Code's snow table sets for your county or township. Large roofs, and especially roofs that step down from a taller section, collect drifting snow, so the truss design has to account for it. The table's figures are higher along the Lake Michigan shore and in the north than in the southeast.

How do I keep a big vaulted barndominium warm?

Put the insulation in the roof plane and seal it well, choose windows that meet or beat the energy provisions in force when you apply, and consider in-floor heat on a slab or basement floor. Big open volumes are comfortable in a Michigan winter when the envelope is designed for it from the start.

Does a larger house need a larger septic system?

Often. Where there is no sewer, your county or district health department permits the system under its own sanitary code, so the rules vary by county. More bedrooms and baths generally mean a larger system and more space on the lot.
