DADU Home Building Services in Seattle, WA

A detached accessory dwelling unit can turn part of your property into a separate home for a family member or another household. QH Build helps Seattle homeowners plan and build DADUs with comfortable layouts, private entrances, and spaces designed for everyday living.

A DADU is an independent residence in a separate building on the same property as the main house. Often called a backyard cottage, it includes its own kitchen, bathroom, and living areas. As a DADU builder in Seattle, QH Build guides your project from the first design discussion through permits and construction.

DADU Options for Your Seattle Property

The right design begins with how you want to use the new home. An open studio layout may suit one occupant, while a separate bedroom can provide more privacy. A larger household may need additional sleeping space and storage, depending on what the property can accommodate.

Placement also shapes the project. The entrance, paths between buildings, window locations, and outdoor areas all affect how the two homes function together. As a detached ADU builder in Seattle, QH Build helps you explore these decisions before developing detailed construction plans.

Our DADU Design and Construction Process

We begin by discussing your priorities and reviewing the property. This gives us a starting point for the floor plan, building placement, and features that matter to the future occupants.

During design, we consider the new residence alongside the existing home. Utility connections, construction access, and the relationship between indoor and outdoor spaces all need attention. QH Build coordinates the permitting steps and manages DADU construction in Seattle, keeping you informed as the project progresses.

Planning these elements together helps establish a practical sequence for the work. It also gives you a clearer understanding of how the new unit will fit into your property before construction begins.

A Backyard Cottage Designed for Daily Life

A backyard cottage in Seattle should offer the comfort and functionality of a complete home. A practical kitchen, useful storage, and a clear flow between rooms can make a compact layout easy to live in. Windows and natural light help shape the atmosphere of each space.

Privacy matters outside the unit as well. We consider how entrances and windows face the main house and where occupants will spend time outdoors. Exterior materials and architectural details can connect the two buildings visually while giving the DADU its own character.

QH Build develops each project around the property and its intended use, creating a separate home that works for both households.

What Our Customers Say!

A DADU is a detached accessory dwelling unit: an independent home in a separate building on the same property as the primary residence. It includes spaces for living, sleeping, cooking, and bathing.

In Seattle, backyard cottage is a common name for a DADU. The building must be designed and approved as a dwelling unit; a garden office or recreation room without the necessary residential facilities is a different type of space.

Start with a review of the lot and your proposed project. Available space, site conditions, access, utility connections, and applicable requirements help determine which options are practical. QH Build can help you explore these factors during planning.
