Ordered a shed floor. Fast and efficient service. Had to guess where strengthening struts went. Could do with clear guidelines. Good people to deal with.


I've had the shed for about 6 years now. No signs of any corrosion. I recently had a need to move it and it came apart with ease. My recent purchase was for the wooden floor. It fitted ok after I figured how to place the metal spacers. All in all, good quality products with great comms. Recommended.

Delivery took a bit longer than advertised due to a stock take which meant that timings for receipt of the bike store became a bit difficult. It was fairly straight forward for an experienced handy man to put together and is working very well. It fits one men's and 2 ladies bikes ....just! We had to take a picture to remind ourselves how to get the bikes back in after we got them to fit the first time as it is quite an art to get the 3 adult bikes in.
