These Grosfillex Utility 11 sheds are perfect where trouble-free storage of garden tools and smaller equipment is required. They are made using the highest quality UV-resistant, durable PVC and are 100% maintenance-free. No painting or preservative is required, and this plastic garden shed is also rot proof and rust proof.
The ‘stay dry’ weather-proof design of the Grosfillex Utility 11 Blue Grey will ensure your contents remain protected and dry. Double doors are supplied as standard, and are secured with a handle & lock. No floor is supplied with this building, therefore a solid base is recommended. The Grosfillex Utility 11 is available in 2 colours – Pale Blue or Pale Green, both with matching roofs and white trim.



The Grosfillex Utility 11® range of PVC plastic sheds are made to an extremely high standard, using the best quality virgin uPVC. This ensures a non-yellowing finish, great product stability and much more substantial weight in the finished product. The walls are 26mm thick and are double-skinned. Windows are made from strong, safe Perspex.
All products in the Grosfillex Utility 11 range are 100% maintenance-free, and won’t need any preservative treatment or maintenance other than the occasional cleaning of the main building and oiling of moving parts, which will ensure that your building lasts for many years.
Grosfillex Utility 11® plastic sheds are supplied in flat-pack form with comprehensive assembly instructions, and normally 2x people can complete the job in 6-8 hours. A firm concrete base is recommended to make a sound job, however it can also be fitted to decking or patio paving slabs. All sheds come with full assembly instructions, fixings and fastenings.
