About Bicknell Builds

ADU Construction Services by Bicknell Builds

Building an accessory dwelling unit (ADU) is one of the more practical ways homeowners can create additional living space without relocating. Across the greater Seattle area, many property owners are turning to ADUs to house family members, generate rental income, or accommodate long-term guests. Bicknell Builds has developed experience helping local homeowners convert unused space into finished, functional living units.

An ADU is a self-contained living space located on the same property as the primary home. It can be attached or detached, depending on the homeowner's goals and the specific layout of the lot. Options range from a compact backyard cottage to a conversion of an existing part of the house. Each configuration offers a level of flexibility that a standard home addition typically cannot provide.

There are several common reasons homeowners pursue an ADU. Some are looking to house aging parents who want proximity without sacrificing independence. Others need space for adult children, frequent guests, or a dedicated home office. Many homeowners in the greater Seattle area also use an ADU as a rental unit, creating a steady additional income stream. With housing demand continuing to grow in the region, an ADU can also contribute meaningful value to a property.

What to Expect When Working with Bicknell Builds

It's common for homeowners to feel uncertain about where to start when considering an ADU project. The process involves planning, budgeting, permits, and coordination across multiple stages. Bicknell Builds structures their process around clear communication and organized project management, so clients understand what to expect at each step.

From initial planning through to the final walkthrough, the team at Bicknell Builds stays involved throughout the project. Their focus includes accurate scheduling, maintaining clean worksites, and delivering a finished space that is ready for use. The goal is to build with long-term durability in mind, producing an ADU that holds up over time and adds genuine value to the property.

Both detached ADU and attached ADU options are available, and each can be designed to complement the existing style of the home. Whether a homeowner is looking for a granny flat, an in-law suite, or a standalone backyard cottage, the team works to match the design to the property and the homeowner's specific needs.

How an ADU Differs from a Standard Home Addition

A home addition expands the square footage of the main house but remains part of the same living space. An ADU functions differently — it operates as a fully independent unit with its own kitchen, bathroom, entrance, and layout. This distinction makes it suitable for use as a rental, a private family space, or a guest accommodation, without altering the structure of the primary home.

In a competitive housing market, an ADU can also improve the resale value of a property. Because it functions as a separate unit, it offers potential buyers additional flexibility that a standard addition does not.

If you are considering an ADU on your property, Bicknell Builds can walk you through the options, review your site, and explain what your lot can realistically support. Whether the goal is a private space for family or a rental unit that generates income, Bicknell Builds works to deliver a result that fits the homeowner's objectives from the start.

"Chris and his crew are fantastic! Every step of the kitchen remodel process was clearly communicated and all details were noted. Chris has the most transparent and thorough quotes I've ever seen with extremely faircompetitive pricing. His communication with us was always immediate and constant. Clinton and Bart were working behind the scenes making sure everything was lined up and the new items purchased and on hand. Andy, the lead carpenter, was extremely polite, professional, on time, and great at his job. He managed the sub contractors and always followed up with any issues right away. Zack was super helpful clearing out all of the old and helping deliver and install the new. The sub contractors cabinets, plumbing, and electrical were all fantastic and did an amazing job. It took us a while to find Chris we talked to over six other general contractors and I'm glad we didn't settle for any other business. He has set a new standard for everything you could wantexpect in a GC. Hiring him will be the best choice you made for your next project."

"We had our shower redone by Bicknell Builds and were so happy with all aspects - their quality of work, responsiveness, punctuality, cleanliness, attention to detail, and overall customer service. The end product was perfect and they got the job done within the estimated timeframe. We would highly recommend Bicknell Builds. See before after pictures."

"Chris and his team did a great job on a downstairs bathroom renovation which came out amazing as you can see from the photos. They are reliable, super communicative, and make sure the work is done right. Renovations are always tough, but they made the process as painless as possible. We've hired Bicknell Builds for several projects now, and they will continue to be our first choice in contractors going forward."

"I recently finished a major remodel and addition to my 1950s war box home. This remodel involved fully replacing the plumbing and electrical and doubling the size of the house. While a number of complications arose in the project as they always do, Chris and team were excellent communicators. It is clear that Chris possesses a personal integrity that is a part of the Bicknell Builds ethos. Chris was honest, respectful, and resourceful throughout. My newly remodeled home is beautiful and hardly recognizable from its previous form thank goodness!."

"Bicknell Builds is a very talented and high quality contractor. This is the second project I have hired them to execute. In this case: glass partitions, a glass pivot door, and a new borrowed-light interior window were added to an existing condo. Because this was a remodel, Bicknell had to work with existing walls and beam conditions that were not plumb or level, yet the glass system was fully square. Bicknell recommended using reveals on each side that could be scribed to the wall and would allow them to fix the existing surface imperfections. Excellent result! And they completed the Project for less than the contract estimate, which is always a happy ending."
