I got a plot for first time earlier this year and the shed is not very stable , i wanted to replace the shed with another that i have. The existing shed sits but there is a drop of quite a few feet as previous plotter had underfloor heating type so i would like to raise the level when i remove existing hut. I was thinking of raising the level with concrete blocks and level so i can build new hut level with my greenhouse , does that sound like a good idea? I thought the concrete blocks would be suitable as they will support the new hut and prevent any rot and keep it secure. If this doesn't sound like a great idea suggestions would be welcomed.
