We are your best source for home additions, from planning and design to construction. Discover how K-Co can expand your living space and add value to your home. We added over 2,000 square feet of living space including a studio with its own bathroom and a laundry/potting room. The cramped old-fashioned kitchen was opened up to the living area to create a high-ceiling great room. Outside, a new driveway, patio and walkway incorporate brightly colored surfaces as a contrast to the abundant greenery of the garden.
