Backyard ADUs Built On Site in the Kansas City Metro
Tiny Terra Homes designs and builds Accessory Dwelling Units (ADUs) right in your backyard, serving the Kansas City Metro area across both Kansas and Missouri. As a dedicated ADU builder and backyard cottage builder, they manage the entire process from start to finish — including permits, stamped engineered plans, and all required inspections. Whether you're looking for a studio, a one-bedroom, or a two-bedroom ADU, Tiny Terra Homes offers a clear and structured path to getting it built.
What makes Tiny Terra Homes stand out as an ADU contractor is their commitment to building on site rather than simply delivering a prefabricated shell. Every unit is constructed directly on your property, ensuring a custom fit, quality control throughout the build, and a result that genuinely adds value to your home.
They offer three distinct build paths to accommodate a range of budgets and levels of involvement:
- Shell — A lower-cost, entry-level option
- Hybrid — The best value for most clients
- Turnkey — A fully finished, move-in ready ADU
Three Build Options to Fit Every Budget
Shell Package — This is the most budget-friendly option, ideal for those who want to complete some of the work themselves or in phases. The Shell package includes a post and beam foundation, framing for walls, roof, and floors, roof and wall sheathing to make the structure weather-tight, as well as permit drawings and engineered stamped plans. Site work, utility runs, doors, windows, and interior finishes are handled separately. Pricing starts at $50,000–$53,000 for a 660 sq ft model and $57,000–$61,000 for a 750 sq ft (2-bedroom) size.
Hybrid Package — Considered the best value, the Hybrid option builds on everything in the Shell package and adds exterior dry-in work including siding, windows, and a finished roof. Installed doors and windows are included, along with rough-in electrical and plumbing. Interior finishes, HVAC, and final hookups remain the client's responsibility. Pricing ranges from $84,000–$101,000 for 660 sq ft and $95,000–$115,000 for 750 sq ft.
Turnkey Package — For clients who want a completely stress-free experience, the Turnkey package delivers a fully finished accessory dwelling unit ready for immediate occupancy. This includes everything in the Hybrid package plus interior finishes such as flooring, cabinetry, and countertops, full plumbing and electrical hookups, and a complete HVAC system. Pricing starts at $168,900 for 660 sq ft and $191,000 for 750 sq ft.
Final pricing depends on site conditions, utility connections, finish selections, and foundation type.
