Alamo Custom ADUs

Uncompromising design-build excellence for constructing ADUs on Alamo’s most distinguished properties.

From grand, detached guest houses to beautiful pool-side cabanas with full living quarters, we craft high-end ADUs that reflect the prestige of your Alamo property. By managing the architectural planning and the heavy construction simultaneously, we deliver breathtaking secondary homes without the traditional friction of remodeling.

Luxury Backyard Homes in Alamo

The spacious estates in Alamo offer a fantastic canvas for expansive luxury ADUs. However, building on these properties often means adhering to strict HOA guidelines, matching highly custom exterior finishes, and integrating complex new utility lines across large distances. We focus on getting the hidden infrastructure—like enhanced foundations and robust trenching—perfectly aligned before we raise a single wall.

Strict HOA and Zoning Compliance

Many Alamo neighborhoods have stringent architectural review boards. We act as your liaison, ensuring the proposed ADU meets all local setback, height, and stylistic guidelines before ground is broken.

High-End Structural Engineering

Grand ADUs with vaulted ceilings and large window walls require sophisticated engineering. We integrate heavy framing and complex truss systems into our designs early on, ensuring proper structural integrity.

Long-Distance Utility Integration

Sprawling estates require extensive trenching to run sewer, water, and power to a detached unit. We expertly manage this groundwork to preserve your mature landscaping and hardscaping.

Estate Logistics and Care

Navigating gated entries and protecting pristine grounds requires a white-glove approach to logistics. We schedule all heavy equipment and trade work to minimize noise and respect your estate’s privacy.

ADU Design / Build Process

1. Initial Site Visit: 1 to 1 ½ hrs

Every ADU starts with a vision, and this starts with a walkthrough to see what you have and understand what you want. By listening closely to your goals, vision, questions, and budget, we help you unlock the full potential of your ADU. With so many creative ways to configure compact spaces, whether it is a rental, guest suite, or a small home, it all starts with understanding how you want to live.

Step 1 – What To Expect

On site walkthrough to evaluate the starting point and discuss the overall goals of the project.
We provide a free ballpark construction cost, which will be a significant range.
This ballpark helps us understand if a client’s budget aligns with our estimated construction cost.
To proceed, we sign our preconstruction agreement (PCA), which includes the various services you will need to design and ultimately acquire the building permits.

2. Design & Material Selection: 3 - 4 weeks

Once the vision is clear, the design process brings it to life on paper. From countertops to cabinet layout to lighting, we’ll plan each detail with precision. A thorough design phase is key to staying on budget. Also, it’s often the fun part!

Consultations for all project goals and design considerations.
Some common design goals include careful attention around kitchen and bathroom design, lighting options, fixture selections, as well as exterior hardscape and landscape. The contractor creates an all-inclusive list of all project selections for client review and interaction. This single tool will be used to guide the project to the finish line.

3. Permitting: 2 - 3 months

Once the design is complete, it’s time to submit the plans to the city for approval. Approval time for an ADU can vary, but generally this will take around 2 – 3 months to get approved. The good news is that you can still keep the project moving! While most product selections will have already been considered, this is the time to actually start finalizing selections and shopping for items. Top on that list will often be key components for kitchen and bathroom, flooring, appliances, and fixtures.

4. Construction: 4 - 8 months

Finally, our team begins by carefully protecting your home and the surrounding areas. For attached ADUs, we install dust barriers with zipper doors and run HEPA air filtration to keep the air clean and the rest of your home undisturbed. Floor protection and other precautionary measures are also put in place. A dedicated team and project manager will carry out the work in coordination with the residents, with clear working hours established from the start.

5. Move In!

Upon passing our city final inspection, we will then do a thorough walkthrough, to ensure everything is just right. We will also provide and go over all of your new documentation, including manuals, warranties, etc., as well as provide a long term maintenance plan to help you make sure your ADU stays beautiful for years to come!
