A detached accessory dwelling unit can create a private home for family members or another household on your existing property. QH Build helps Kirkland homeowners design and build DADUs with practical layouts, comfortable living areas, and a thoughtful connection to the surrounding outdoor space.
A DADU stands separately from the main house and includes its own kitchen, bathroom, and living space. As a DADU builder in Kirkland, QH Build guides your project from initial planning through design, permits, and construction.


Your plans for the new home should shape its design. A compact backyard cottage may suit one person who wants an independent living space. A layout with a separate bedroom can provide more privacy, while an additional bedroom may be useful for a larger household.
The property also helps determine what is practical. Building placement, access, outdoor space, and the relationship to the primary residence all need consideration. As a detached ADU builder in Kirkland, QH Build helps you explore these decisions before developing the construction plans.
We start by discussing how you intend to use the unit and what its occupants need. This helps us plan the rooms, storage, entrance, and everyday movement through the home. We then review the property to understand how the proposed building could fit.
During design, we consider the site and the home together, including utility connections and access for construction. QH Build coordinates the permitting steps and manages DADU construction in Kirkland, keeping you informed as the project moves forward.
Early planning also gives you an opportunity to consider how the two homes will share the property. Entrance locations, paths, and outdoor areas can help each household enjoy privacy while maintaining convenient access.
A backyard cottage in Kirkland should feel comfortable throughout the day. Natural light, useful storage, and a practical kitchen layout can make a smaller home easier to live in. Thoughtful room placement helps create a balance between shared living areas and private spaces.
The exterior should work with the property too. We consider materials, windows, and the building’s relationship to the main house. Whether you prefer a contemporary design or a cottage that complements your existing home, QH Build develops the project around your needs and the characteristics of the lot.
A DADU is a detached accessory dwelling unit: an independent residence in a separate building on the same property as the main home. It includes its own spaces for living, cooking, and bathing.
A backyard cottage can be a detached ADU when it is designed and approved as an independent dwelling unit. A garden room or office without the facilities needed for residential use is a different type of space.
Start with a review of your lot and proposed project. The available space, site conditions, access, and applicable requirements help determine which design options are practical. QH Build can help you explore these factors during planning.
