Choosing the Right Custom ADU Builder for Your Project

Custom ADUs are designed for homeowners whose property, goals, or design preferences require a tailored approach. Unlike pre-designed layouts, custom ADU projects allow for flexibility in size, layout, finishes, and architectural style while responding directly to site conditions and intended use. This service is part of Hive ADU’s broader construction services and is ideal for projects that require a more personalized design-and-build process. Our ADU design services provide a path to a successful custom ADU build.

What Defines a Custom Built ADU

A custom ADU begins with a blank design framework rather than a fixed model. This approach allows the unit’s layout, size, and configuration to be shaped around the property instead of adapting the property to an existing plan. Whether you envision a private guest suite, additional rental income, or an inspiring home office, our tailored approach ensures every aspect, from size and layout to finishes, aligns with your vision and complements your existing home.
