I needed a greenhouse to fit a very restricted space, the one I purchased was the best for the situation I had. The delivery was far quicker than quoted. The contents were correct. The price was lower than competitors. Any slight queries with construction plans were explained by my telephone contact. You do need a bit of experience when constructing these kits on your own but nothing is to insurmountable. The greenhouse does the job. I am seriously considering demolishing my garden shed which, is now beyond economic repair within the next 12 months. I may replace it with a condierably larger green house from this company and use it for a dual purpose construction. I would seriously recommend that you use the steel bases provided and raise the height by constructing a solid base to provide both extra head and growing room. All round this is a good company which supplies a very cost effect solution. I have already recommended this company to a friend. DO NOT BUY A GREENHOUSE FROM AN INTERMEDIATE OR GARDEN CENTRE WITHOUT DUE RESEARCH AND UNLESS YOU HAVE A GOOD BANK BALANCE
