Custom ADUs

MASON Architects offers a streamlined process to take an ADU project from design to permit approval. Our experienced team can recommend trusted contractors and be on hand throughout the entire construction process to ensure the project is completed efficiently.

While there are numerous ADU companies and prefab products available, our clients have often encountered significant compromises in terms of floorplans and finishes, resulting in limited savings. When it comes to enhancing property values by matching the existing architectural vernacular and level of detail, seamlessly integrating an ADU into a site, or when specific floorplans or basements are desired, opting for a custom ADU is the superior choice.

Moreover, many properties in Woodside face site development constraints, such as steep slopes and septic issues. These challenges often become the primary impediment to ADU approval and can cause significant delays and even derail the process. The MASON Architects design team has extensive experience expediting projects requiring septic upgrades through the San Mateo County Health Department.

We design custom ADUs tailored to our clients’ individual preferences and objectives, and to the site. We have experience integrating ADUs into primary development plans as well as executing site upgrades, and have successfully designed attached and detached ADUs, ADUs above garages and within main residences.
