We can make Pergolas to your own design and specification. With all construction projects the various members have to be strong enough to support themselves, and to look effective the proportions of posts size to rails has to be right.
Below is a suggestion of component sizes for a pergola, which may prove helpful in your planning. If you would like help just bring a layout plan into our office with main length and width, and any height restrictions, and we can work out the rest.
