One of GBGC’s signature specialties is the construction of Accessory Dwelling Units (ADUs), also known as granny flats, mother-in-law suites, or granny units. An ADU is a self-contained living space built on the grounds of a single-family home, offering a distinct and independent housing option separate from the main house. Perfect for rental income, multi-generational living, or guest accommodations, ADUs combine functionality with design elegance. Our team excels in crafting tailored ADUs that integrate seamlessly into your property, enhancing both its value and utility. Let GBGC turn your vision into reality with innovative ADU designs that reflect your style and needs.
