Best Barndominium Design Software in 2026: 7 Options Compared

What to Look for in Barndominium Design Software

Most barndominiums start with a simple rectangle, for example 40 by 60 feet (about 12.2 by 18.3 m), and that is exactly why the planning inside matters so much. A good program has to handle a large open space, a shop or garage with wide doors, lofts, porches and a roof that spans the whole building. These are the points that decide whether a tool is right for your project:

• House and shop in one model: living area, garage, workshop and storage should be planned together, with exact wall positions and door sizes.
• Roof and structure: wide gable roofs, shed roofs over a lean-to, dormers and the beams that carry an open span should be part of the program, not something you model by hand.
• Exact dimensions: you need real lengths and wall thicknesses that your builder and steel or post-frame supplier can work with.
• Drawings for the permit and the builder: floor plans, sections, elevations and DWG or PDF files, not only pretty 3D views.
• Cost: most people design one barndominium, not fifty. A professional subscription is hard to justify for a single project.

Building Configurators vs. House Planning Software

Many barndominium projects start with a 3D designer from a metal building or post-frame supplier. These tools are excellent for choosing the size, roof style, colors, doors and wainscot of the shell and then sending the design in for a quote. They are made to sell a building kit, so they stop where the house begins. House planning software plans the home inside the shell, and that is the part your family will live in every day:

1. Plan7Architect: Best Overall Barndominium Design Software for Complete House Plans

Price: $259.99 Original price was: $259.99.$169.99Current price is: $169.99. one-time purchase, lifetime license, no subscription
Platform: Windows desktop software
Best for: owner-builders, families and contractors who want to plan the complete barndominium, from the shell to the last outlet, and hand real drawings to the builder

Plan7Architect is a dedicated house planning program that works with real building objects. You draw a wall, and it already has a thickness, layers and a height. You place a large sliding door for the shop or a row of windows for the living area, and the openings are created automatically. Every change in the 2D floor plan updates the 3D model, the sections and the elevations at the same time, so you never draw anything twice.

Open Floor Plans, Lofts and Shop Space

The typical barndominium combines a great room with kitchen and dining area, a bedroom wing, a garage or workshop and often a loft above. In Plan7Architect you plan all of this in one project with unlimited floors and buildings, so an attached shop, a separate garage or a guest house can sit right next to the main building. You enter exact lengths, angles and distances, the dimensions are created automatically, and the living and usable areas are calculated for you. With plan variants you can compare two layouts, for example a larger shop against a fourth bedroom, without starting over. For layout ideas, see our article Barndominium Floor Plan Ideas.

Roofs, Porches and Beam Structures

The roof is what makes a barndominium look like one. Plan7Architect constructs gable, hip, shed, flat and mansard roofs automatically, including dormers. Wide porches, decks, terraces and railings are planned directly on the house, and with custom beam structures and timber construction tools you can show exposed beams in the great room or the posts of a post-frame building. These are the building tools you will use most on a barndominium:

• Automatic roof construction for gable, hip, shed, flat and mansard roofs, including dormers
• Timber construction tools and custom beam structures
• Foundation planning, slabs, floors and ceilings
• Stairs to the loft and unlimited floors and buildings in one project
• Decks, terraces, balconies, railings and garden objects
• Terrain modeling with contour lines and sloped lots
• Electrical, heating and plumbing planning
• Custom windows and doors, including large shop doors

Drawings for the Permit, the Builder and the Supplier

Sections, elevations and complete plan sheets with title blocks are created directly from your model. You can print them to scale, save them as PDF or export DWG/DXF files for your builder, your engineer or the company that supplies the steel or post-frame shell. Plan7Architect makes the creation of building permit drawings much simpler, and every element you customize, such as a special wall structure or a shop door, can be saved to the catalog and reused. If you are also planning a classic barn for animals or equipment, our guide Planning a Barn Yourself with Plan7Architect shows the workflow.

3D Walkthrough and Renderings

You can walk through your barndominium in 3D at any time to check sight lines, ceiling heights in the loft and the view from the porch. For photorealistic images and videos, you export the model to Twinmotion with all textures included. The program is made for beginners without CAD experience, and video tutorials take you from the first wall to the finished plan.

Pricing

You buy Plan7Architect Pro once for $259.99 Original price was: $259.99.$169.99Current price is: $169.99. and keep using it for as long as you like, with activation on up to 3 PCs. For comparison: Chief Architect Premier costs $1,995 per year, so planning and adjusting a barndominium over a two-year build costs $3,990. Cedreo Pro at $79 per month billed annually comes to $948 per year.

2. Chief Architect Premier: Professional Residential Design with Post-Frame Tools

Price: $1,995 per year or $229 per month
Platform: Windows and Mac
Best for: professional residential designers and builders who produce barndominium plans every week

Chief Architect Premier is a powerful professional program for residential design. It has automatic building tools for walls, roofs, footings and slabs, can place posts and girts automatically for post-frame buildings, generates trusses and purlins, and creates construction documents, schedules and material lists from the model.

For a single barndominium, the price is the main issue: one year costs more than ten times as much as Plan7Architect Pro, and the program is built for daily professional use with a long learning curve. If you are comparing both, see our Chief Architect alternative page.

3. Steel Building and Post-Frame Designers: Best Free Start for the Shell

Price: free online tools from suppliers such as Wick Buildings; the building itself is priced by quote
Platform: web browser
Best for: choosing the size, roof style and colors of the shell and getting a price from a supplier

Metal building and post-frame suppliers offer interactive 3D designers for barndominiums. General Steel lets you adjust roof pitch, porch overhangs and entry points, Wick Buildings DESIGN 3D offers dormers, porches, wainscot and L- or T-shaped layouts with a walk-around 3D view, and Walters Buildings provides pre-engineered barndominium plans you can modify before requesting a quote. These tools are quick, visual and connected directly to a real building package.

Their purpose is the exterior shell and the sales process. Interior floor plans, kitchens, bathrooms, electrical layouts, sections and permit drawings for the living space are not what they are made for, so you will still need house planning software or a designer for the home inside.

4. Cedreo: Fast Browser-Based Concepts for Home Builders

Price: free plan for 1 project; Personal $139 per project; Pro $79 per month billed annually
Platform: web browser
Best for: builders and sales teams who want quick 2D and 3D concepts and renderings for clients

Cedreo is easy to learn and very fast for presentation work. Walls, roofs and dormers are generated automatically, elevations and sections come from the model, and the rendering quality is strong, which helps builders sell barndominium designs to clients.

Cedreo is focused on concepts and sales rather than detailed construction work. Files are exported as DXF, structural options such as beams and post-frame framing are limited, and the subscription adds up if you keep working on your project. Read more on our Cedreo alternative page.

5. SketchUp: Flexible 3D Modeling for Barndo Concepts

Price: free web version for personal use; Go $129 per year; Pro $399 per year
Platform: web browser; Pro also as Windows and Mac desktop software
Best for: people who enjoy 3D modeling and want to sketch the shape and look of a barndominium

SketchUp is quick to start with and very flexible, and the 3D Warehouse offers models of metal roofs, sliding barn doors and furniture. Many barndominium fans use it to try out the shape of the building and the porch.

SketchUp is a general modeling program, so walls, roofs and framing are drawn as geometry, often with extensions. Exact floor plans, sections and plan sheets take a lot of manual work in LayOut, which is only included in the paid plans.

6. Planner 5D: Easy Interior Layouts on Any Device

Price: free plan; Premium $59.99 per year; Professional $399.99 per year
Platform: web browser, Windows, Mac, iOS and Android
Best for: trying out room layouts and furniture for the living area

Planner 5D is very easy to use. You drag rooms, doors and furniture into place and see the result in 3D immediately, which is a fun way to test how a great room and kitchen could be furnished.

For a complete barndominium it reaches its limits: there are no sections or permit drawings, roof and structural options are limited, and CAD export is only included in the Professional plan.

7. RoomSketcher: Clean Floor Plans for Presentations

Price: free plan; Pro about $144 per year
Platform: Windows, Mac, iPad and Android tablets
Best for: clear, colored 2D and 3D floor plans to show family, a lender or a builder

RoomSketcher creates attractive floor plans quickly and is easy for beginners. It is a good tool for presenting a barndominium layout in a clean, readable way.

It is a floor plan tool, not a building planner. Roofs, beams, foundations, sections and permit drawings are outside its scope, so it covers only one part of a barndominium project.

How to Choose the Right Barndominium Design Software

• You want to plan the complete barndominium, inside and out, with permit drawings: choose a dedicated house planning program like Plan7Architect.
• You want a price for a steel or post-frame shell: use the free 3D designer of your supplier, then plan the interior in house planning software.
• You design barndominiums professionally every week: Chief Architect Premier, if the subscription fits your business.
• You sell barndominiums and need fast client renderings: Cedreo is built for that workflow.
• You only want to test furniture layouts: Planner 5D or RoomSketcher are enough for that step.
