Very useful. Prices could do with being updated more regularly but I accept that this can be  a difficult and lengthy process. Plans work well in conjunction with the website.

Clear, well thought-out garden room plans that are genuinely practical to follow. Everything is laid out in a logical order and feels based on real build experience rather than theory. On top of that, the customer service was excellent and very helpful. Would definitely recommend to anyone planning a DIY garden room.

I thought this was a great idea. I was a complete novice at building anything but the plans had details drawings, instructions and a parts list. Lots of lessons were learnt along the way and a bit of frustration. But on the whole I loved this project.

Top Tips

Frame

Time spent getting the frame true and level will make the build much easier.

Wire mesh

Wire mesh under the base will stop vermin from getting under the building.

Roof slope

Make sure the roof has a minimum slope of 25mm per metre!
