Very disappointed with the quality of the Vantage 250 we have just purchased from Dunster House, thinking that we were buying a good quality product. . Delivery was fine, but no installation service so it took 2 people 3 days to assemble all the pieces at a cost of £350. The rain leaked through the wood underneath the windows so rang customer services. and I was advised to email and wait for a response. After a few days of torrential rain I solved the problem with applying clear sealant. Now completed installation and painting to preserve the life of the summerhouse. The spruce wood used it very poor quality and covered in knots. , splits, splinters and hundreds of nail holes. The pinewood used in our garden shed is much better quality and cost a fraction of the price. Although installed following the instructions the windows are badly fitting and rattle. The floor and roof are made from MDF material not wood. Dunster House is advertised as the No. 1 compared with other companies selling similar products. Marketing, photos and descriptions are very misleading. To avoid disappointment do not use this company to buy a summer house. Very poor service.
