Every project reflects our passion for design that connects people — today and for years to come.

A reimagined home for life’s next chapter, including a bright, modern kitchen remodel, an expanded family room, a new laundry and flex space, and an upgraded home office.

Specializing in Aging in Place
Sun Design specializes in reinventing living spaces so that they can be enjoyed for years to come. We work closely with clients to anticipate future needs including aging in place (what we like to refer to as Thriving-in-Place), family expansion, kids leaving home, and family members entering their golden years. The end result of a Sun Design home remodeling project is always a transformation – a change for the better – through the creative use of light and space.
