Pergolas are designed with an open-roof design that allows for sufficient sunlight and air circulation. Open-top pergolas are most often placed in the garden to create an appealing focal point and a magnificent outdoor space and increase the value of your home. It’s common for homeowners to use pergolas as a simple but appealing way to create an outdoor extension of their living space. If this is your goal, choose a design and material that will complement the exterior of your home, and have the pergola attached to your home for a seamless transition from inside the home to a lovely outdoor patio.
