2 Story Barndominium Floor Plans in Colorado

A two-story barndominium puts more living space under less roof, which is why it makes sense at Colorado elevations where the snow load is heavy and on building envelopes too tight for a sprawling ranch. The trade is height. A taller sidewall catches more wind, and parts of Colorado publish some of the highest design wind speeds in the country. Where your parcel falls on the snow and wind maps your jurisdiction uses decides whether the building can follow the IRC's prescriptive rules or needs a site-specific engineered design.

What actually changes with this feature

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

Wind on a taller wall

Doubling the wall height roughly doubles the wall area the wind pushes on and lengthens the lever arm at the base, so a two-story frame needs more bracing, stiffer connections and heavier anchorage than a one-story on the same site. Give the building supplier the wind speed your jurisdiction publishes for the parcel — never a default — and the exposure category.

Snow on a smaller roof

For the same living area, a two-story plan has roughly half the roof of a ranch. At high elevations, where the ground snow load in Larimer County's table climbs past 100 psf, that can save more framing than the extra wall height costs. A simple gable over the whole footprint sheds snow best.

Stairs and the second floor structure

In a clear-span barndominium, the second floor is a structure built inside the shell — a framed or steel mezzanine on its own posts or hung from the frame. Decide which early, because it changes the frame design. The stair takes about 40 to 50 square feet on each floor; place it where it does not cut the great room in half.

Upstairs bedrooms and escape openings

Every sleeping room, upstairs included, needs an emergency escape and rescue opening under the IRC as adopted by your jurisdiction. On a steel building with horizontal girts, plan the window openings with the frame design so the girts can be framed around them.

Less roof, more wall

Your jurisdiction's snow and wind maps set the limits

Unincorporated Larimer County's structural design sheet shows how the two loads pull in opposite directions. It allows homes to follow IRC prescriptive design only where ground snow loads do not exceed 70 psf and design wind speeds are under 140 mph; beyond those limits, design moves to the building code and ASCE 7. The county's snow table reaches 70 psf at 6,000 feet and 110 psf at 8,000 feet, and its basic wind speeds range from 115 to 225 mph, set from the Colorado Front Range Gust Map published by the Structural Engineers Association of Colorado or the county's own wind map. A two-story plan halves the roof exposed to snow, but its taller wall and higher eaves take more wind. Along the foothills of the Front Range the wind often governs; on high, sheltered mountain lots the snow often does. Most steel and post-frame barndominium packages are engineered for their site anyway, and a Colorado-licensed engineer's design to your jurisdiction's actual values is what makes a two-story shell work.

Common ways to build this

Common configurations. Yours does not have to match one exactly — this is a starting point for the conversation, not a catalog.

Full two-story with bedrooms upstairs

1,300 sq ft main / 1,300 sq ft upper

Kitchen, living, dining and a guest bath on the main floor; three bedrooms and two baths upstairs. The most efficient use of roof and foundation, and the best choice for a tight building envelope or a heavy-snow site.

Main-floor primary suite, two bedrooms up

1,700 sq ft main / 800 sq ft upper

The primary suite stays on the main floor for ageing in place, and the second floor covers only part of the plan so the great room can be vaulted to the ridge. A popular compromise between the ranch and the full two-story.

Shop below, living above

2,400 sq ft shop / 1,600 sq ft upper living

The ground floor is a clear-span shop and garage; the living quarters sit above. It suits small building envelopes and gives the living space views over the land. The floor between shop and living space needs the fire separation your jurisdiction requires, and the shop slab can be designed separately from the living floor.

2-Story Barndominium: common questions

6 common questions about this layout in Colorado. If yours is not on the list, ask it directly.

Is a two-story barndominium more expensive?
Per square foot of living space it is often similar or lower, because the roof and foundation are smaller. The stair, second-floor structure and taller walls add cost; the smaller roof and slab save it. The balance depends on your site's snow and wind values. We do not publish our own prices; the survey gathers your parcel details for a real estimate.
How does Colorado wind affect a two-story barndominium?
Parts of the Front Range have very high design wind speeds; unincorporated Larimer County's published basic wind speeds range from 115 to 225 mph depending on location. A two-story wall catches more of that wind, so the frame, bracing and anchorage are designed to the value your jurisdiction sets for your parcel.
Do I need an engineer for a two-story barndominium?
Usually. Steel and post-frame building packages are generally engineered by the supplier's Colorado-licensed engineer, and some jurisdictions only allow the IRC's prescriptive rules below set snow and wind limits — Larimer County's are 70 psf ground snow and 140 mph wind. Your building department will say what it requires.
Can a post-frame barndominium be two stories?
Yes. Post-frame buildings can have a second floor built on its own posts or carried by the main columns, designed by the building's engineer. Longer columns and more bracing are needed than for a one-story building on the same site.
Is two stories better at high elevation?
Often, because the roof — which carries the heaviest load at elevation — is smaller. Unincorporated Larimer County's ground snow load table rises from 55 psf at 5,000 feet to 110 psf at 8,000 feet, so halving the roof area matters more the higher you build.
What do I need before a two-story plan is drawn?
Your parcel's elevation and your jurisdiction's snow and wind values, whether the second floor will be a framed mezzanine or part of the main frame, the stair position, and which rooms must be on the main floor for the long term.
