Coffee goes out the kitchen door to the back porch before the house is up. The Glen is a single-story 2-bedroom, 2-bath barndominium, about 1,850 square feet on a 40×50 footprint: a kitchen open to a vaulted living and dining room, a walk-in pantry, and porches front and back. The office sits by the front door, behind its own door, with windows on two walls. One of you takes the desk, the other the porch.

The Floor Plan

Presentation floor plan. Room areas are finished square feet. Kitchen and bathroom layouts are illustrative; the final design is yours. Written dimensions govern over scaled dimensions.

Key Features

  • Every room on one level, with a 4 foot wide hallway under a tubular skylight and seven 3 foot interior doors
  • A 20′ × 24′ living and dining room under a vaulted ceiling, the largest room in the house, with the front door opening into it through the foyer

Tour The Glen

The Heart of the Home

Step in through the foyer and the 20′ × 24′ living and dining room opens under a vaulted ceiling. The 20′ × 16′ kitchen opens off it, vaulted too, wrapping a walk-in pantry behind a barn door. One cooks, one sets the table, and the kitchen open to the living room keeps the cook in the conversation.

The Master Suite

Cross the living room to the vaulted 14′ × 15′ master bedroom, a twin window on its end wall. Its own bath opens off it, and beside the bath, with its own door from the bedroom, a 6′ × 16′ walk-in closet. The second bedroom is across the house: a late reader and an early sleeper never share a wall.

The Office

Step off the foyer into the 14′ × 9′ office, behind its own door, with daylight from two sides, a twin window on the front and one on the end wall. Its own closet sits behind a sliding door. One of you works in here with the door shut; a guest who stays a week gets the same room.

Work & Service

Walk the 28 foot hallway under a tubular skylight, the 16′ × 12′ second bedroom at one end and the 12′ × 7′ mud room at the other. The hall bath and the laundry open off it, the laundry behind a barn door. The boots come off in the mud room, through its own outside door.

Outdoor Living

An 8′ × 36′ covered porch faces the front and an 8′ × 36′ porch runs along the back, 576 square feet of covered outdoor space. The front door opens under one, the kitchen's sliding door under the other. Each is 8 feet deep, room for a table. Afternoons, one of you sits out front by the living room window.

Not included, handled by local professionals

  • Foundation design: by your local structural engineer for your site, using the anchor bolt plan and loads from your building supplier
  • Engineering drawings for the structure (provided by your chosen supplier)
  • Plumbing, electrical and HVAC layouts, by your local trades to local code

Can I Build This?

Yes: every page is designed for standard pre-engineered metal building (PEMB) construction. Stamped structural drawings come from your building supplier's engineer, and permit review is with your local building department.

Why a pre-engineered metal building?

A PEMB encloses more home for the money than a wood-framed building and goes up in weeks. Its steel frames carry the roof, so no inside wall has to hold it up: the kitchen, living room and master bedroom can be vaulted. The frame layout on these pages follows standard metal building practice, so a supplier can quote it as drawn.

Who does what

We design the home: the rooms, where the doors and windows go, the elevations and the roof. Your building supplier engineers the steel frame for your site and confirms the vaulted ceilings against it. That is the usual split on a metal building project, and our pages are drawn to it.

Every plan is designed and informed by the IRC (USA) and NBC Part 9 (Canada): room sizes, bedroom egress windows and door and hallway clearances are checked on every plan before it goes on sale.

Steel or wood?

Same home, same rooms, same plan set, same price. What changes: what holds the roof up, who builds it, how you get a price.

Steel framingWood framing
Shell goes up✓Faster: the frame and panels arrive cut and drilled, bolted up in a week or two.Slower: framed on site, stick by stick, over several weeks.
Getting startedMade to order; allow factory lead time.✓Lumber is on the shelf; start when the slab cures.
Waste on site✓Little; cut to size at the factory.More; offcuts and scrap.
Crews and materialsNeeds an erector who knows metal buildings.✓Any framing crew and lumber yard.
Inspectors, appraisers, lendersMost know steel homes; a few ask questions.✓Everyone knows a stick-framed house.
Open interiors✓Nothing inside holds the roof up: the frame clears the whole width, so walls can move and rooms open up.On our 40 ft span plans one interior wall carries the roof trusses and stays put; the rest are partitions.
The look inside✓Steel columns and beams can stay exposed, or be boxed in.✓Conventional walls and ceilings.
Insulation✓Blanket or spray foam between the steel.✓Standard batts in the 2x6 walls.
Sustainability✓Recycled content; recyclable at the end of its life.✓Renewable; keeps storing carbon for the life of the house.
Termites, rodents, decay✓The frame does not rot or feed termites.Open to termites, rodents and decay unless kept dry and treated.
Fire and fire zones✓Non-combustible frame, walls and roof: what wildfire codes ask of the outside of a house, and a class insurers rate.Metal roof and panels help; the framing behind them is combustible.
Insurance✓Often priced lower; ask your insurer.Standard homeowner rates.
Who engineers itYour building supplier's engineer, stamped, in the package.Your roof truss company's engineer; walls to code as drawn.
Cost to build this plan$310,000 to $360,000$365,000 to $415,000

How you get a price

Steel framing

With the design set, get shell quotes from metal building suppliers (they engineer the frame for the size and shape of this home and your local wind and snow loads); upgrade to the construction set (coming soon) for firm bids from local trades on the slab and interior.

Wood framing

With the design set, get budget quotes this week from a local framing contractor and a roof truss company you already know; upgrade to the construction set (coming soon) for firm project bids.

Pick the framing your local builders can quote; the rooms are the same either way.

What Will It Cost to Build?

$310,000 to $360,000

A home like The Glen is estimated to complete for $310,000 to $360,000 with you as your own general contractor, hiring the trades yourself. That covers the steel building and putting it up, the foundation, the inside finish, and an allowance for site work, utilities, driveway and septic.

It leaves out land, financing, sales tax, payroll taxes and insurance on labor, appliances beyond a standard allowance, landscaping and window coverings. Hiring a general contractor adds about 15 percent.

This is a rough estimate, not a quote. Costs vary by region by 15 to 25 percent, and your building supplier and local contractors will price it for your area. Our barndominium buying guide walks through what moves the number.

Frequently Asked Questions

Is this a house for the long run?

It is all on one level, with no stairs anywhere. The hallway is drawn 4 feet wide, and every door into a room is at least 3 feet wide; only the closet doors are narrower. The office takes a guest without giving up a bedroom. Thresholds, the shower and grab bars are decided with your builder.

Where do the cars go?

Outside. The Glen has no garage or carport, so the whole 40′ × 50′ building is house, with no garage to build, roof or heat. The mud room's own outside door is the working entrance from a driveway or a detached building. If you want a garage under the same roof, see the plans with a garage below.

Can I build The Glen with any metal building supplier?

Yes. Every page is designed for standard pre-engineered metal building (PEMB) construction, so any steel building supplier can quote this home as drawn. Their engineer then provides the stamped engineering drawings for the steel building, along with an anchor bolt plan and the loads for your site, and your local structural engineer designs the foundation from them.

Is the plan stamped, engineered, or permit-ready?

No. No plan set is a permit. This design set is for quotes, budgeting, and financing; permit review comes later, on a construction plan set (ours is launching soon) with the engineering your building department requires. The Glen is designed and informed by the IRC (USA) and NBC Part 9 (Canada). Local permit review is between you, your builder and your building department.

Is a steel barndominium a good choice in a wildfire zone?

Yes, with the rest done right. The steel frame and the metal wall and roof panels do not burn, the kind of construction wildfire rules favor. A metal roof also carries the top fire rating, Class A. Ember-resistant vents, boxed eaves, tempered windows and cleared ground around the house decide the rest. No home is fireproof.

Is a steel barndominium a good choice on the coast?

Yes. Your building supplier's engineer designs the frame, its bracing and its anchor bolts for your site's wind speed, and the stamped drawings say so. The windows, doors and panel fasteners decide the rest. Buy windows and doors rated for your wind zone, and fasten the panels to the engineer's schedule, which says how many fasteners go where.
