- A conversion of underused space (e.g. converting basement, garage, or unused attic into livable space)
These expansions can serve many purposes — guest quarters, home office or studio, income rental, multigenerational living, or simply giving your family more breathing room. Homeowners choose us because River City is trusted Accessory Dwelling Units Watertown Company.
