Im looking to build a 10x10 garden room. I have artificial grass 1 side and patio the other and the room would go over both. What would be the best base without concrete. Are there any good mounts. Thanks
I put cheap patio slabs 500x500 onto concrete & hardcore and rested my cabin via timber sub frame onto that. Put 20mm shingle all around to avoid rain splashback
I would look to build a timber sub frame and use patio slabs (as above) at suitable positions where you have the artificial grass, assuming the existing patio area is sturdy. You want a FIRM and LEVEL base, the patio slabs need to be FIRM and a timber sub frame allows you to make it LEVEL.
Have a look at this thread, very similar. https://community.screwfix.com/threads/die-lorelei-2017.187656/
