Barndominiums—barn-style homes built from metal or steel shells—have rapidly gained popularity due to their cost-effectiveness, durability, and design flexibility. Whether you’ve purchased a basic shell kit or had a metal structure erected on your property, the next step is transforming that blank slate into a space that fits your lifestyle. Customizing a barndominium shell is where creativity, function, and personalization come together.
In this guide, we’ll walk you through how to take a barndominium shell and turn it into a fully functional, comfortable, and stylish living space that reflects your specific needs, budget, and taste.
1. Understand What a Barndominium Shell Includes
Before diving into customization, it’s essential to understand what a typical barndominium shell comprises. Most shell kits include:
- Metal or steel framing
- Exterior walls and roofing
- Windows and doors (optional)
- Basic foundation plan
At this stage, it’s a weatherproof structure without interior walls, electrical, plumbing, or finishes. This open canvas gives you the flexibility to design the layout and features just the way you want.
2. Define Your Lifestyle Needs and Goals
Customizing a barndominium shell begins with determining your lifestyle requirements. Ask yourself:
- How many bedrooms and bathrooms do I need?
- Do I need an open-concept kitchen and living area?
- Will I need a home office, gym, workshop, or hobby space?
- Is accessibility or aging-in-place a concern?
- How much storage is necessary?
Understanding these priorities will help you design a layout and choose finishes that make the most of your shell space.
3. Plan Your Interior Layout
Once your needs are clear, sketch or work with a designer to map out the interior layout. The open nature of a barndominium shell allows for incredible flexibility.
Layout Tips:
- Use structural framing efficiently: While many barndominiums have few interior support walls, placing rooms around existing structural elements can reduce costs.
- Embrace open-concept designs: Maximize the feeling of space by combining kitchen, dining, and living areas.
- Zone your spaces: Keep private areas (like bedrooms) separate from noisy or communal ones.
- Consider ceiling heights: Lofts or vaulted ceilings can be added for drama or functionality.
Pro Tip: Use 3D design software or architectural drawings to visualize flow and spacing.
4. Customize Plumbing, Electrical, and HVAC
Once your layout is planned, the mechanical systems come next. These are critical and often must be installed before interior walls go up.
Plumbing:
Plan out all bathrooms, kitchen fixtures, laundry, and potential future additions like outdoor showers or mudrooms.
Electrical:
Think beyond the basics:
- Where will you need outlets?
- Do you want smart home integration?
- Will there be exterior lighting or power for workshops?
HVAC:
Barndominiums need thoughtful insulation and temperature control. Options include:
- Mini-split systems for zone control
- Radiant floor heating
- Central HVAC with well-placed ductwork
5. Select Interior Finishes
Interior finishes bring personality and comfort to your barndominium. This is where your style truly shines.
Walls:
- Drywall for a traditional look
- Shiplap or wood paneling for rustic or farmhouse charm
- Exposed metal or brick for industrial flair
Flooring:
- Polished concrete (affordable, modern, and durable)
- Luxury vinyl plank (LVP) (water-resistant and stylish)
- Hardwood or laminate for warmth and elegance
Ceilings:
Vaulted ceilings can be accented with wood beams or finished in white for a bright, airy feel.
Lighting:
- Use a mix of recessed lighting, pendants, and accent fixtures.
- Take advantage of natural light by installing large windows or skylights.
6. Incorporate Storage Solutions
One downside of open-concept living is a potential lack of storage. Plan for this early:
- Built-in shelves
- Overhead loft storage
- Mudroom cubbies
- Walk-in closets and pantry areas
If your shell has tall ceilings, consider installing mezzanines or storage lofts.
7. Exterior Customization Ideas
Don’t forget that the outside of your barndominium is equally important. Curb appeal and functionality matter.
Siding and Paint:
- Metal panels come in a variety of colors, but you can add wood accents or stone veneer to break up the look.
Porches and Decks:
- Add a wraparound porch, covered patio, or rooftop deck for extra outdoor living space.
Landscaping:
- Gravel driveways, raised garden beds, and fire pits all enhance the property.
Garage or Shop Additions:
- Customize your shell to include attached or detached garages, workshops, or RV bays.
8. Accessibility and Aging-in-Place Features
If you’re planning to age in your home or want it to be accessible for all, customize the shell early with these features:
- Wide doorways and hallways
- No-step entries
- Walk-in showers
- Lever-style handles and smart controls
These changes are easier and more cost-effective during the design stage rather than after completion.
9. Sustainability and Energy Efficiency Upgrades
Barndominiums can be very energy-efficient if designed with sustainability in mind.
Insulation:
Use spray foam insulation in walls and roofs to improve thermal efficiency.
Windows:
Opt for double or triple-pane, Low-E windows for energy savings.
Solar panels:
Install solar energy systems on your roof or property to reduce utility bills long term.
Rainwater collection and greywater systems can also be integrated if you’re aiming for off-grid or eco-conscious living.
10. Work with Professionals
While DIYing some aspects is possible, working with experienced contractors, designers, and engineers will help you avoid mistakes and maximize your investment.
- Architect or designer to finalize your layout and aesthetics
- General contractor for project management
- Electricians and plumbers to meet code requirements
- Interior designer if you want help pulling together a cohesive style
Always ensure permits are secured, and your project complies with local zoning and building regulations.
