PERGOLAS. Although they look somewhat unfinished to the untrained eye, pergolas do provide shade.
The size of the beams and their spacing will determine exactly how much shade is provided, though a pergola on its own can never create a fully shaded space.
It provides a sitting area that allows for breeze and light sun, but offers protection from the harsh glare of direct sunlight. Pergolas also give climbing plants a structure on which to grow.
And yes, a pergola will add market value to any house. Since outdoor living has become more popular than ever, the value of properties with a pergola or a comfortable outdoor space has been on the rise. A safe gauge for a deck or backyard improvement is about 50% — 80% for your return on investment.
