The Lifetime range of heavy-duty plastic sheds are made with durable, dual-wall High-Density Polyethylene (HDPE), reinforced with a rigid powder-coated steel framework. That means they are ready for the worst of British weather while offering all the benefits of low-maintenance. No more sanding, staining or rotting wood. Lifetime sheds offer a good level of security and practical storage shelving. Best of all they come with shatter-proof windows and well-positioned skylights to give your shed natural light and a sense of space.
