Home Additions & ADUs for your Austin home
An Austin home addition or ADU begins with a clear purpose for the new space. A guest area, larger living room, or separate dwelling can involve different design and construction needs. Watt & Werner helps you explore the intended use, its relationship to the existing home, and the questions that need to be resolved before defining the work.
Begin with how the space will be used
Before discussing square footage, consider what the new space needs to do. Privacy, access, storage, and its connection to the existing home all influence the right approach.
We help bring those needs into a conversation about the property and the scope of the work.

- Additional bedrooms and living areas
- Expanded kitchens or primary suites
- Dedicated home offices
- Guest accommodations
- Spaces for multigenerational living
- Accessory dwelling units where permitted
Make the new space feel like it belongs
An addition should be considered alongside the existing home. Rooflines, exterior materials, light, circulation, and interior finishes all play a part in making the result feel connected.
Understand the property first
Local rules, setbacks, utility capacity, site access, and structural conditions can shape what is possible. These questions need to be explored before settling on a final plan, budget, or construction schedule.
A clear path from idea
to finished home.

Before we begin.
Is an ADU the same as a home addition?
An addition expands the existing home. An accessory dwelling unit is a separate dwelling on the property, subject to applicable requirements. Tell us how you want to use the space so the project can be evaluated accordingly.
Can you confirm whether an ADU is possible on my property?
Feasibility requires a review of the specific property and proposed use. Share your location and any existing plans so site conditions and applicable requirements can be part of the discussion.
How do we get started?
