At Kanga Room Systems, we offer two distinct architectural styles — both available in a wide range of floor plans, and each can be built in any size we offer as either full turnkey construction or a shell you finish yourself.

Modern Style

Sleek, contemporary design with a flat roof, clean lines.
Popular for backyard studios, rental units, and minimalist homes.

Cottage Style

Traditional charm with a gable roof and cozy, pitched profile.
A great fit for family living, second homes, or guest cottages with character.

Kanga Room Systems Reviews

"We had a really great experience with Kanga, ended up with a beautiful, very well constructed home, and absolutely would use them again. The quality of the build was simply impeccable. After we built the Kanga, we had the property reappraised and the Kanga added more than its own price in value to our property."

Christina L.

"The cabin looks absolutely fantastic! My husband and I are so glad we found Kanga and that we didn't end up with a cookie cutter cabin design. Ours is much cooler!"

Andi G.

"From the owner on down, this company cares deeply about the families they serve and the structures they are building. The intentional design for items like the ladder to the loft has made it possible for me to access the loft easily and safely. The quality of their craftsmanship is superb. I am very grateful to Kanga Room Systems for the forever home they built for me."

Frequently Asked Questions

What’s the difference between a shell install and a turnkey build?

A shell install includes the full exterior structure—walls, roof, siding, doors, and windows—completely built by Kanga. The inside is unfinished, so you or your contractor complete the electrical, plumbing, and finishes.

A turnkey build is move-in ready. It includes interior finishes, bathroom and kitchen fixtures, flooring, water heater, and more—everything except kitchen appliances and utility hookups.

Do I need a permit for a Kanga build?

In many rural areas of Texas, no permit is needed—especially for buildings under 200 sq ft, like small studios or offices. However, requirements vary by location, so we always recommend checking with your local authority. Our team can help guide you through the process.

What styles of buildings do you offer?

We offer two architectural styles: Modern: Flat roof, clean lines, steel window frames, and a contemporary look. Cottage: Gable roof, traditional charm, and cozy character. Both styles are available in all sizes and can be built as shell installs or turnkey homes.

How much does a Kanga build cost?

Pricing depends on the size, style, and whether you're going turnkey or shell.
As a general guide: Shell installs start around $44,000 - Turnkey builds start around $105,000 and Larger turnkey homes can exceed $350,000.

How are the buildings delivered?

If your site allows, many Kanga cabins can be delivered nearly fully assembled. This reduces onsite construction time significantly. We offer delivery and installation across most of Texas, with additional charges for remote locations.

Do you build outside of Texas?

We offer kits for customers in most U.S. states. However, installed shells and turnkey builds are currently only available in Texas. If you're out of state, we can ship you the materials and recommend working with a local contractor.

Do your buildings include HVAC, plumbing, and electrical?

Yes, turnkey homes include all rough-in and finish-out work for HVAC, plumbing, and electrical. We also install fixtures like toilets, vanities, water heaters, and lighting. However, you'll need to provide kitchen appliances and arrange final utility hookups.
