Groceries in from the garage through the mud room, no stairs anywhere. The Bramble is a single-story 2-bedroom, 2-bath barndominium, about 1,550 square feet on a 40×50 footprint: a kitchen open to a vaulted living and dining room, a 1-car garage with a carport beside it, and porches front and back. The 24′ × 16′ master bedroom has a sliding door onto the rear porch. Two chairs go out on the back porch the first evening.

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

  • No stairs anywhere, with seven 3 foot interior doors and a 4 foot wide hallway under a tubular skylight to both bedrooms and the hall bath
  • A kitchen open to the vaulted living and dining room, with a walk-in pantry behind a barn door (a door that slides on a track outside the wall)
  • Vaulted ceilings over the kitchen, living and dining, and again in the master bedroom; 9 foot ceilings in the rest of the living space
  • A 24′ × 16′ master bedroom with its own sliding door onto the rear porch, its own bath, and beyond the bath a 6′ × 16′ walk-in closet with a window
  • A 12′ × 20′ second bedroom in the north-west corner with daylight from two sides, windows on the back and west walls, and a reach-in closet behind a sliding door
  • A mud room entry from the garage, with the laundry behind its own door and a tubular skylight overhead
  • An enclosed 1-car garage and a 12′ × 24′ carport beside it
  • Porches front and back: 26 feet of covered entry, a 36 foot rear porch, 496 square feet in all, each 8 feet deep, room for a table
  • Tubular skylights pulling daylight into the hallway, hall bath and mud room
  • A 4:12 gable roof over a 12 foot eave

Tour The Bramble

The Heart of the Home

Step in from the front porch and the 14′ × 20′ living and dining room opens under a vaulted ceiling, the 12′ × 15′ kitchen open to it in the corner, vaulted too. Two windows and the front door face the porch; a barn door off the kitchen hides the walk-in pantry. Whoever is cooking stays in the room.

The Master Suite

Walk down the hallway to the 24′ × 16′ master bedroom, vaulted, with a sliding door onto the rear porch and room for a king bed and a chair. Its own bath opens off it, and beyond the bath a 6′ × 16′ walk-in closet. One reads in the chair while the other sleeps on.

The Second Bedroom

Next door, the 12′ × 20′ second bedroom takes the north-west corner with daylight from two sides, a window on the back wall and one on the west. The hall bath opens off the hallway under a tubular skylight. A guest wakes to light from two windows and unpacks into the reach-in closet behind its sliding door.

Work & Service

Come in from the garage and the 10′ × 6′ mud room takes the coats under a tubular skylight, the laundry behind its own door. The 14′ × 24′ garage has a 10 foot overhead door. A 12′ × 24′ carport stands beside the garage. Both of you drop the boots in the mud room, one door from the car.

Outdoor Living

An 8′ × 26′ covered porch faces the front and an 8′ × 36′ porch runs along the back, 496 square feet of covered outdoor space. The front door opens under one, and the master bedroom's sliding door under the other. Whoever sits out back at the end of the day has 36 feet of shade to choose from.

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$295,000 to $345,000$360,000 to $410,000

Owner as general contractor. Rough estimates, not quotes.

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?

$295,000 to $345,000

A home like The Bramble is estimated to complete for $295,000 to $345,000 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 an easy house to live in for a long time?

It is all on one level, and you come in from the garage through a mud room. Seven interior doors are 3 feet wide and the hallway is drawn 4 feet wide. At about 1,550 square feet there is less to heat and clean. Thresholds, the shower and grab bars are decided with your builder.

Why a carport as well as a garage?

The carport gives a second vehicle, a visitor or a trailer a covered spot without the cost of a second garage bay. The 1-car garage is enclosed and opens into the house through the mud room; the 12′ × 24′ carport stands beside it. Both sit on the same side of the house, away from the porches.

Can I build The Bramble 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 Bramble 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.
