Whether it is cheaper to build a pergola or buy one will depend on the style and size of the pergola and the chosen material, whether you are building a pergola on a deck or as a standalone structure.
'You can find box section prefabricated aluminium and steel structures on the market, although these can be quite expensive,' explains John Wyer.
Simple wooden structures can be more cost effective, although you need to ensure that it will be the correct size and look for your garden.
'Installing pergolas requires some technicalities and it’s important to ensure the structure can withstand high winds amongst other things – I’d recommend getting professional advice on this,' advises John Wyer.
