Barndominiums have become one of the fastest-growing housing trends thanks to their modern appearance, open floor plans, durability, and affordability. Whether you're building your dream home, a vacation retreat, or a live-work space, choosing the right barndominium kits is an important first step toward a successful project.

One of the biggest questions buyers have is what actually comes with a barndominium kit. While every manufacturer offers slightly different packages, most kits include the essential structural components needed to construct the building shell. Understanding what's included—and what's not—helps you budget accurately and avoid unexpected costs during construction.

This guide explains the typical components of a barndominium kit, optional upgrades, and additional expenses you should plan for before starting your project.

What Is a Barndominium Kit?

A barndominium kit is a pre-engineered building package designed to simplify the construction process. Rather than sourcing materials individually, buyers receive a coordinated set of structural components manufactured to precise specifications.

Most kits are engineered for durability, quick installation, and flexible floor plans, making them suitable for residential living, workshops, home offices, and mixed-use spaces.

Primary Steel Frame

The steel frame forms the structural foundation of the building.

Most kits include:

Steel columns
Main support beams
Rafters
End-wall framing
Base plates
Structural connectors

The frame is engineered to meet local building code requirements for wind, snow, and other environmental loads.

Secondary Framing Components

Secondary framing provides additional structural support while securing the roof and wall panels.

Typical components include:

Purlins
Wall girts
Eave struts
Roof supports
Framing connectors

These elements distribute loads evenly throughout the building and strengthen the overall structure.

Roof Panels

The roof system protects your home from the elements while enhancing energy efficiency and durability.

Most kits include:

Galvanized steel roof panels
Protective coatings
Ridge caps
Roof trim
Fastening hardware

Many homeowners also choose insulated roofing systems for improved indoor comfort.

Exterior Wall Panels

Wall panels create the building envelope and contribute to the overall appearance of the home.

Available options often include:

Vertical panels
Horizontal panels
Multiple color selections
Ribbed steel designs
Protective finishes

These panels are designed for long-term durability with minimal maintenance.

Trim and Flashing

Trim provides both functional and aesthetic benefits by sealing joints and creating a finished appearance.

A typical kit includes:

Corner trim
Base trim
Eave trim
Gable trim
Ridge trim
Door and window flashing

Properly installed trim helps protect the building from moisture intrusion.

Fasteners and Assembly Hardware

A complete barndominium kit includes the hardware needed to assemble the structural shell.

Common hardware includes:

Self-drilling screws
Structural bolts
Nuts
Washers
Connection clips
Closure strips

Using the supplied hardware ensures compatibility with the engineered design.

Engineering Drawings and Building Plans

Engineering documents are among the most valuable parts of a barndominium kit.

These typically include:

Structural drawings
Assembly instructions
Anchor bolt layouts
Material lists
Engineering calculations

These documents simplify construction and assist with permit applications.

Optional Features and Upgrades

Many manufacturers allow buyers to customize their kits with additional features.

Popular upgrades include:

Roll-up garage doors
Entry doors
Windows
Skylights
Covered porches
Lean-to additions
Roof ventilation systems
Decorative trim
Multiple exterior colors

Adding these options during the design stage often reduces future installation costs.

What Is Usually Not Included?

While barndominium kits include the structural shell, several important components are generally purchased separately.

These often include:

Concrete foundation
Interior framing
Plumbing
Electrical systems
HVAC equipment
Insulation
Drywall
Flooring
Cabinets
Fixtures
Appliances
Interior finishes
Landscaping

Understanding these additional costs helps you create a more accurate project budget.

Benefits of Choosing a Barndominium Kit

Many homeowners choose barndominium kits because they offer significant advantages over traditional construction.

Some key benefits include:

Faster construction timelines
Durable steel construction
Lower maintenance requirements
Flexible floor plans
Open interior layouts
Energy efficiency with proper insulation
Resistance to pests and fire
Long-term value

These benefits make barndominiums an attractive option for modern homeowners.

Planning Before You Buy

Before purchasing your kit, take time to evaluate your project requirements.

Consider the following:

Building Purpose

Will the building serve as a primary residence, vacation home, or mixed-use property?

Property Requirements

Ensure your property can accommodate the building while meeting local setback and zoning regulations.

Customization Needs

Decide which upgrades are essential before placing your order.

Budget

In addition to the kit itself, budget for:

Foundation
Site preparation
Utilities
Interior finishing
Permits
Landscaping

Proper planning helps prevent unexpected expenses during construction.
