Where possible, Dunster House are committed to procuring wood products that have been certified against credible, internationally recognised standards for good forest management, to ensure that material originates from well managed forests. On pressure-treated timbers, you may notice some subtle striation marks. These marks sometimes appear during the drying process of timbers. Fear not! In time, the marks will begin to fade as the sun starts to lighten the wood.

Assembly Time: 1 - 2 Days This time is an approximation, based on two people building the basic product with no added extras. Assembly time may vary with additional items such as roof shingles, or external circumstances like the weather. We totally understand that DIY is not for everyone and it can be very overwhelming to start building your own garden product. Therefore, you may want to consider getting in touch with a local carpenter or handyman to install it for you.

Fully Pressure Treated - All our timber gazebos & pergolas are fully pressure treated as standard, reducing the likelihood of rot and insect infestation. We take the pre-cut lengths of timber and place them in a large pressure treatment tank, where the timbers are impregnated with a non-toxic preservative. We add a colourant during this process, giving the timber a rich brown colour.Additional Information: Installation - We do not offer installation. All our garden buildings have been designed for the DIY market and supplied with full pictorial instructions and YouTube tutorials.
