Why Plan a Deck With a Pergola?

A deck can be a retreat you return to again and again with family and friends. As an extension of the home or a setting in a quiet corner of the garden, a deck serves many purposes: entertaining, dining, outdoor cooking, gardening, hot tubs, and relaxing. A timber frame deck is also kid-friendly, giving children more room to play in a clean space where you can join them. An overhead pergola adds shade and protection from the weather for year-round use.
