|

Hi all, I am undertaking a project soon to build a greenhouse for garlic and onions over the winter and for herbs and chillies next year.
Want to get peoples opinions on it and see if they think it will withstand the weather.
Thanks in advance for your replies.

Whereabouts in the country are you, Wardy? How exposed/sheltered is your site? Will your greenhouse be on soil or a hard surface like concrete or gravel? How big will it be? |

I am in East Galway near Ballinasloe, my site is a third of an acre with high trees on two sides and hedges on a third. The trees are high enough to take the brunt of the wind but not to black out the sunlight on the majority of the back lawn. I would be building on grass not concrete even though I have a big enough yard to be able to build the greenhouse on but we have plans to extend the house in the next couple of years. The greenhouse would be 10 foot by 14 and The walls are 6 foot high. Reason I didn't pick a poly tunnel was that I wanted to take on a project like this and a friend of mine built a greenhouse recently, similar to the one in the plans and it looks really well. Plus I like the idea of a wooden frame one. |

soundslike you will be moving it in the near future, that could be a bigger job to move it than build it. |

I think he meant he's going to build it on grass and leave the yard free for his extension.
Hey Wardy maybe you could enlist your friend's help since he's built one already? |

You were right about building on grass, I am just waiting on some of the wood to be delivered and my friend said he will clear his schedule for 2 days and help me out. |

|

Finally, I have progress, between weather and getting good help it took a lot more time than I expected. I finally got the frame of the greenhouse built and I went for polytunnel plastic rather than pvc sheets because money is not flowing.
My cousin, who is a very tidy carpenter, was invaluable and donated loads of his free time to help me and a work collegue helped me out a lot as well.
I will post another reply when all the roof edges are nice and smooth and the strips and plastic are on.
I have a table to put into it and 3 raised beds but I have to kill the grass and put in a floor and some sort of crude irrigation system running off a water butt i got.

What is the DPC detail and would you not be better putting it up on some blocks or a concrete ring beam to protect the sole plate from rot? _________________ “It’s my field. It’s my child.

There is a much thicker wooden plate wrapped in agricultural polystyrene underneath the wooden frame. If I get a nice evening this week, it will be wrapped and the ground will be covered to kill the grass and then raked. There will be 3 raised veg beds made from untreated timber and a table put in once the cover is on and the door.
I admit I would be better off putting it on a concrete base but I will be changing the layout of the back of my house next year or the year after and didn't want to be digging up a concrete base.
Because I am a bit of a noob here I have no idea what DPC is. |

Polystyrene??? Or polythene? That timber will sweat and eventually rot if completely surrounded.
I cannot help but wonder, why not put it in its final place now? If there is a good reason not to, then put lifting eyes in the base plate so as the whole construction can be easily moved when you need to do it without dismantling.
I didn't mean a whole concrete base, just under the walls. Alternatively lay blocks on a sand bed and strap it down - it will save the timbers from rotting. _________________ “It’s my field.

Thanks for the advice Tagwex, I will see about moving it onto blocks on a sand base, suppose now is the time before it start making additions to it.
I will post updates as I have them. |
