Custom Accessory Dwelling Unit (ADU) Design

Home by Tom is an ADU home builder that is flexible to your needs. We partner with you to provide expert services you need for a personalized ADU. You can bring us your plans that have already been drawn up, and we’ll take it from there, or we can design your ADU from scratch.

Detached ADU Walnut Creek

A detached ADU allows you to build a standalone house that is separate from the main house. There are different types of detached ADUs, and Home by Tom can help you build a well-designed dwelling that meets your specific needs. We are proud to be affordable ADU builders in Walnut Creek

Sometimes referred to as a granny flat, mother-in-law suites are gaining popularity and offer a perfect living space that accommodates independent living for an elderly parent.

This is similar to a mother-in-law suite. The difference is that an in-law suite accommodates more than one person in the ADU, allowing elderly parents to live safely and independently close by.

Design a mini version of a regular ADU that converts part of your home into a self-contained living space. It is an affordable way of utilizing an existing area of your home.

Design a separate space close to your pool that is more than just a changing room. It will provide a living space where guests/family can stay and provide easy access to the swimming area.

Attached ADUs Walnut Creek

Your trusted ADU builder in Walnut Creek can help you build an attached ADU that is an addition to the existing primary residence. Typically, these are added to the back or the side of the house with one or more connecting walls.

Maximize unused garage space by converting a portion of your garage into an ADU. This increases your living space and property value and can serve as a rental unit.

This type of ADU builds on the attic space by using windows and extending the roof line, thus creating more headroom. The natural light adds more function to the space, i.e. office, bedroom.

Soak up some sun in a comfy sunroom built by your trusted ADU contractor in Walnut Creek. A sunroom boosts your mood, brightens up your home, allows you to connect with nature, and saves energy.

Make use of the attic in your home and convert it into an office, guestroom, or bedroom. You’ll get much more out of your attic than just storage space.

Even if your lot does not permit a detached ADU, there might still be an option to build an attached ADU that connects to the main residence, allowing your in-laws to stay close.

We recently hired Home by Tom to convert our outdated laundry room into a fully functional bathroom, and the results exceeded our expectations in every way. From the very first consultation, Tom and his team were attentive, professional, and genuinely invested in understanding our vision.

They walked us through the entire process, design, plumbing, electrical, and finishing with clear communication at every stage. The team offered creative solutions to space constraints and incorporated high-end fixtures and modern design elements that made the new bathroom feel both spacious and luxurious.

What really stood out was their attention to detail. Every tile was perfectly aligned, the lighting was thoughtfully placed, and they managed to keep the project on schedule and within budget. They also maintained a clean and safe worksite throughout, which we really appreciated as we continued living in the home during construction.

We wouldn’t hesitate to recommend Home by Tom to anyone looking to reimagine a space in their home. It’s rare to find a contractor who combines craftsmanship, reliability, and design insight so well
