Full-Service ADU Construction from Ground Up
Castle Building & Remodeling offers a comprehensive, end-to-end approach to building accessory dwelling units. As an experienced ADU builder, their process begins with the demolition of any existing structures that need to be cleared from the site. Once the area is prepared, the team installs new water, sewer, and electrical connections to ensure the property is fully equipped for construction.
Every build starts with a solid foundation. The Minneapolis Garage crews then frame new walls and roofs, followed by the installation of windows, doors, siding, soffits, and roofing materials — all designed to create a fully weathertight shell. As a dedicated backyard cottage builder, they place a strong emphasis on creating grade-level accessible living units with low barriers to entry, making their ADUs suitable for a wide range of occupants.
Interior Finishing and Mechanical Work
Once the exterior shell is complete, Castle Building & Remodeling's team moves inside to handle the mechanical and electrical installations, insulation, and drywall. This stage is critical in transforming a raw structure into a livable space. As the project progresses, interior finishes are carefully applied, including:
- Interior doors and millwork
- Custom cabinetry
- Flooring and tile
- Countertops and accessories
- Paint and final touches
It is at this stage that the detached ADU truly begins to take shape, with each element contributing to a functional and attractive living environment.
Compact Spaces Built for Maximum Functionality
As a skilled granny flat builder and ADU contractor, Castle Building & Remodeling understands that smaller spaces require thoughtful design and precise execution. Their finished backyard homes are known for packing a remarkable amount of functionality into a compact footprint. Every square foot is considered, resulting in a polished, move-in-ready unit that truly shines.
Whether the goal is to create additional rental income, house extended family, or add long-term value to a property, their team delivers quality craftsmanship at every stage of the build process — from site preparation all the way through to the final coat of paint.
