We use three different manufactures for our Summerhouses, as we’d like to offer a wide range of variety and choices to our customers. One of them offers an installation service free of charge included in their prices, whereas the other two charge extra for that service. This will be made clear as you browse through the options. Add ons and extras such as double glazed glass, toughened glass, Georgian Styled windows and doors, substituted or additional single or double doors, roof shingles, PVC add ons e.t.c aren’t possible for us to display on the website, so please call us for a more accurate price. Models displayed on the website will be standard specification.
