Additions and ADUs

Investing in an ADU or any kind of major home addition can significantly improve your life. Major additions and ADUs can be built within your existing structures, including a garage or a shed, or they can be expansions that free us up to make changes in the layout of the main home too. An ADU can significantly change your property and the way that you use it.

Due to housing shortages, ADUs have become an extremely popular way for homeowners to create new revenue streams, provide space for aging parents, provide space for older children to reside, create new room for entertaining, office space, give visitors their own space, and more. That’s why more than 20,000 ADUS were approved in California In 2011 alone.

All of our ADUs are custom built for your needs, and we’re happy to work with a wide range of budgets. From standalone ADUs to attached ADUs, junior ADUs, and even garage conversions, we have an option for everyone.

At Andrew G Construction, we keep your project on track by working with a network of carefully vetted subcontractors who can handle your unit’s roofing, plumbing, flooring, HVAC, drywall, carpentry, and more. That allows us to finish projects faster and provide more unique materials and construction techniques.

We are also familiar with the regulations involved in building an ADU in San Mateo. We will take care of everything that is needed so you don’t have to worry about a thing during the process.

Whether you want a new guest house, a new passive income source, or the convenience of aging in place for parents, an ADU could be the answer for you.

Most ADUs change their purpose over time, so it’s important to have a sturdy, flexible space that also looks great on your property. Our team excels at looking ahead to your ADU’s long-term use and matching architectural styles to your home, so you’ll always have the space you need.

Bathroom Remodels

For bathroom remodeling, flow is paramount. The choice and placement of your fixtures, storage, and partitions can make the difference between an awkward and cramped bathroom, and one you’ll be proud to own. A big part of this is choosing shower fixtures, doors, and installation options that are easy to clean, easy to use, and won’t leave water all over your bathroom floor. Another big part of any successful bathroom remodel is choosing lights and fixtures that fully light the space, without leaving dark corners. These are just a few of the considerations that go into every one of our bathroom remodel projects. Our remodelers work closely with each homeowner to determine exactly how their bathroom will be used on a daily basis, so your design will be every bit as functional as it is attractive.
