Description from Alton Greenhouses
645mm wide, 1348mm long, 479mm tall at the front, 623mm tall at the back.
This Alton Evolution cold frame is made from the same thick and sturdy cedar profiles as the Evolution range of greenhouses with mortice and tennon joints. Complete with sliding and hinged lids you can open these in a variety of ways including two different heights with the inbuilt cedar props or you can keep them in the closed position but slide them across. At the final stage of hardening off, you can remove the lids completely by simply sliding off, then the walls of the cold frame provide that bit of shelter and warmth.
