Sort reviews by:

Having reached an age where a greenhouse became desirable we researched the avaliable options extensively. 8' x 12' Size was dictated by an existing slab and raised bed base and we decided to go for a mid range aluminium option.Reviews pointed us to the Vitavia greenhouse and "Gardenstreet" were by far the most competitive supplier. Fast delivery (received a phone call after three days to arrange a day) and Adam the delivery driver was a pleasure to deal with. Well packaged and with comprehensive instructions. Erection took a weekend taking time to level and bolt down the steel base properly. Now its glazed its stunning and has just survived fully intact its first 75mph storm. To sum up, Gardenstreet were a pleasure to purchase from and the Vitavia Greenhouse everything we hoped for.
