|

Just bought a 10x6 greenhouse and now need to build the foundations. Site is windy so want to attach it to blocks/concrete on the ground. Anyone got advice before I start this project? I would appreciate any help. |

Is there a base rail with the greenhouse? Or is it sitting directly on the ground ?
If you have a 4 inch base rail you can put U shaped rebar through it and set it in a 2 ft square slab, pour a slab for each corner. Good luck with it. |

Thanks for the response Ian. No base rail so was planning on putting the house directly on blocks and screwing them together. Would I be better buying a base rail and doing what you say? Just want to make sure after the cost of the house the wind doesn't wreck it 😃 |

What I did was I poured a strip foundation, laid standard blocks all the way around, I then screwed treated timber to the top of the blocks, drilled holes in the sill of the greenhouse and screwed the greenhouse to the timber. Unmoveable.
The reason I put it on top of blocks was, I wanted to get a little extra height and like yourself didnt have a base rail, which to me doesnt matter because you are still going to have to secure it anyway. Problem, on a windy site you would think by taking the glass out over winter you are doing the right thing, well I did. Fatal mistake, the wind buckled the frame, but then if I had left the glass in it would most definately have wrecked it anywayl. So no more green house, working on a polytunnel at the moment.  _________________ vegandflowertime.blogspot.ie |

I laid blocks on a sand base. Treated timber on top of the blocks and got some galvanised lateral restraint straps cut at 300 mm long and screwed them together. The bottom rail of the greenhouse has 12 holes in it so i put coach screws through that into the timber. Solid as a rock. _________________ “It’s my field. It’s my child. I nursed it. I nourished it.
