A detached accessory dwelling unit can give a family member or another household an independent home on your property. QH Build helps Bothell homeowners plan and build DADUs that bring together comfortable living spaces, practical layouts, and a thoughtful use of the available land.
A DADU is a separate residential building with its own kitchen, bathroom, and living areas. Often called a backyard cottage, it allows occupants to live independently while remaining close to the main house. As a DADU builder in Bothell, QH Build guides the project from initial planning through design, permits, and construction.


Your goals for the new home should shape its design. A compact studio may work for one occupant, while a separate bedroom creates more privacy. Additional sleeping space or storage may be useful for a larger household, depending on what the lot can accommodate.
Building placement also influences how the property will function. We consider the entrance, paths between the homes, outdoor areas, and views from each residence. As a detached ADU builder in Bothell, QH Build helps you explore these choices before developing detailed plans.
We start by discussing who will use the unit and what they need from the space. This helps establish priorities for the floor plan, room sizes, storage, and access.
Next, we review the property and develop the proposed design. A detached residence requires planning for its structure, utility connections, and access during construction. QH Build coordinates the permitting steps and manages DADU construction in Bothell, keeping you informed about progress and upcoming work.
Considering the home and the site together helps address practical details early. It also gives you an opportunity to decide how paths, landscaping, and outdoor spaces will serve both households once construction is complete.
A backyard cottage in Bothell should feel like a complete home. A practical kitchen, comfortable living area, useful storage, and a clear flow between rooms can make a compact layout easier to use. Well-placed windows bring natural light into the spaces where occupants spend their day.
Privacy deserves attention throughout the design. Entrance locations and window placement can help each household enjoy its own space. We consider these details alongside exterior materials and architectural features to create a DADU that fits the surrounding property.
QH Build develops each project around its intended use, balancing the needs of the new home with those of the existing residence.
