The Alton Evolution Twelve is a large timber greenhouse constructed with the best Western Red Cedar. The Alton Evolution Twelve is a stunning, high quality greenhouse designed to stand out in any garden style. As standard you recieve a double sliding door with toughened safety glass and screw-in cedar bar capping which ensures the glass is held firmly and securely. The gutters, door supports, and base plinth are powder coated aluminium in an attractive 'Moss Green' coloured finish.
The Alton Evolution range is crafted within the UK and machined in Alton’s fully equipped workshop using CNC technology. CNC milling gives highly accurate results, all to bring you a flat-packed building that's easy to install. Improved designs include the use of a metal base plinth that helps to keep the cedar away from the floor, a new glazing system, low threshold access and a unique gutter design - meaning the Alton Evolution is revolutionary in the world of greenhouses.
