Type Five: A New Kind of ADU Builder
Type Five is a housing company based in Berkeley, California, that designs and builds exceptional homes. As an accessory dwelling unit builder, they bring together architects, engineers, and builders under one roof to deliver a seamless, stress-free experience from start to finish. Their innovative approach combines modular design with advanced construction methods, reshaping the way homeowners think about expanding their living space.
At the core of Type Five's offering is a proprietary modular design system — a Lego-like framework that empowers homeowners to customize the size, shape, and layout of their new home. Whether you're looking for a backyard cottage, a granny flat, an in-law suite, or a fully detached ADU, Type Five has the tools and expertise to bring your vision to life.
Custom ADUs Designed Around Your Needs
Type Five's design system is built for flexibility. As a full-service ADU contractor, they offer a wide range of customization options to suit your space, lifestyle, and budget:
- Adjustable footprints — dimensions that flex to fit your backyard and landscaping
- Configurable interiors and openings — layouts, windows, and doors modified to your exact needs
- Vertical scalability — options ranging from different roof profiles to multi-story builds
Their design philosophy prioritizes form, function, quality, longevity, and adaptability. Every detail is considered, from customizable modular kitchens to built-in features that maximize the utility of smaller spaces. As a detached ADU builder, Type Five ensures that each home feels thoughtfully crafted and purpose-built.
