For the amount of time you will spend using it, a pergola is a relatively inexpensive investment that not only expands your living space, but sees you making the most of the warmer months. But how much do they cost?

According to Home Improvement Pages, the size of your pergola and the materials used will determine your overall costs. The best way to compare material costs is to measure the entire area you plan to use and get a range of quotes from either paving installers or decking builders for the floor.

You will also need to select materials for the support structure. One good option is to use treated pine, which is not only durable, but is less expensive than alternative options such as brick or steel.

With a better idea of your costs, you can then decide whether or not you want an open, semi-closed or fully-enclosed pergola. As a general rule, pergolas are open structures, but semi-closed is becoming a popular choice these days and offers the feel of an outdoor room. If opting for a fully-enclosed pergola, it’s important you take into consideration costs such as doors and screens.
