With all the standard features found on the Supreme, 4’ wide double doors, a choice of powder coated finishes and a superb range of accessories makes for a greenhouse with stunning looks and performance truly at home in the larger garden setting. For extra stability and strength, we recommend building a brick base. However an Integral aluminium base with drop doors giving low level threshold is available upon request.
