Custom On-Site ADU Construction by Backyard House

Backyard House is a professional ADU builder based in Austin, Texas, specializing in fully custom, on-site built accessory dwelling units. Every structure they build uses high-quality residential construction materials and methods — the same techniques used in standard home construction. As an experienced accessory dwelling unit builder, they offer a streamlined process that takes a project from initial design all the way through to a finished, permitted living space.

Their approach is built around transparency and simplicity. Every backyard cottage builder project comes with upfront, fixed pricing, a risk-free assessment, and a clear construction timeline. There are no hidden costs — permits, foundation work, climate control systems, and internet connectivity are all included in every quote.

What's Included in Every Backyard House ADU

Backyard House takes a comprehensive approach to each project, ensuring clients know exactly what they're getting from day one. Their builds include a wide range of standard features:

1. Climate Control: A ductless mini split system for efficient year-round heating and cooling
2. Concrete Foundation: Reinforced concrete slab or pier and beam foundation
3. Building Permits: All building and trade permits are handled and included in every quote
4. Wired Internet: Underground Ethernet cable connecting directly to the main house
5. Kitchen & Bathroom Budgets: Allowances for cabinets and fixtures of the client's choosing
6. In-House Design Services: Customization options ranging from minor adjustments to fully bespoke layouts

Clients can choose from existing models or work directly with the Backyard House design team to create a fully custom living space, viewable in 3D before construction begins. As a detached ADU builder, they manage every phase of the project, including engineering, architectural drawings, permitting, construction, and finishing touches such as vanities, lighting fixtures, and flooring.

The Backyard House Construction Process

Backyard House manages the entire project lifecycle in-house. Their process includes:

1. Custom Design Creation — Working with clients to design a space that fits their specific needs
2. Construction Plans & Permitting — Handling all engineering, architectural drawings, and permit applications
3. Building Construction — Using experienced residential contractors and quality materials
4. Finishing Touches — Personalizing the space with fixtures, flooring, and lighting

A typical project runs approximately 9 to 12 months from design to completion, with the construction phase itself taking around 4 to 8 months depending on the scope. For clients who already have city approval in place, construction-only services are also available. They are also willing to collaborate on larger projects, taking responsibility for the ADU structure while other contractors handle additional elements such as pools.

As a trusted ADU contractor in the Austin area, Backyard House provides a reliable, all-inclusive path to adding a high-quality living space to any residential property — without the need to move or alter the existing home.
