The original plastic grid foundation system for garden buildings has evolved into the EcoBase Fastfit system, Not only does Fastfit provide you with a firm, strong, long-lasting and well-drained foundation for your shed, summerhouse or log cabins, but it is quick to install with its grids linked together with simple snap connectors. 

The Fastfit plastic shed base comes with easy to follow assembly instructions and is supplied with a permeable membrane, cut to the size of the building footprint to suppress the growth of weeds. The grids are lightweight so they can be picked up, carried and laid with ease, and snap together to make your base quick and easy to lay. It is suitable for most garden sheds, summer houses, bike stores and log cabins.

Fastfit is made here in the UK from 100% UK recycled plastics, and provides a firm, strong and long-lasting base for your building. It is rot proof, chemically inert and reusable too! For an eco-friendly plastic shed base kit you can rely on, look no further.

The perimeter around your building can also be filled with pea-gravel to produce a French drain and prevent splashback from rain on to your building, helping to keep it looking its best.


  • Simply snaps together it's quick and easy to lay, with no specialist tools or equipment needed
  • Robust and durable providing a firm strong and long lasting base which is rot proof and chemically inert
  • Extendable to create a base for any size of building (which can be added to if you upgrade to a bigger shed)
  • Reusable and ecofriendly, made from 100% UK recycled plastic
  • Time-saving less preparation time, no concrete curing time.

It is essential that this base is assembled strictly in accordance with the instructions supplied.

  • DELIVERING RESPONSIBLY THROUGH THE LOCKDOWN PERIOD AND BEYOND:  We have reorganised our operational processes, which include moving to separate shifts in our operational departments so that our teams are spaced out safely, and changing delivery registrations so that there will not be a requirement for your signature or close contact. We are working hard to maintain a safe and hygienic environment as your building is built and delivered. We would ask for your patience, as it may take longer than normal to deliver your building, but we hope you will understand in the current circumstances. After all, with our exclusive Tiger 20 Year Guarantee the wait will be worth it – we promise!

  • Tigerbox endeavours to deliver garden buildings within the estimated number of working days stipulated. However, we cannot be held responsible for events outside of our reasonable control which may cause slight delays in the delivery time; Please note that this delivery lead time is an estimate, and will depend on external factors we do not have full control of in these unprecedented times. We will keep you regularly updated with the status of any order you place. What we can say is that we believe we make the best value buildings in the UK, with very strong ratings and reviews from customers, and that we have a lot of customers who come back to order again (and again), so while there may be a bit of an extra wait, we're sure you'll feel it will have been worth it.

  • Please note: certain garden buildings may require someone present to assist with the unloading (such as large workshops or log cabins);
