I don't know anything about putting up greenhouses or woodwork.  However, on my allotments there are greenhouses made from wooden frames covered in either some sort of polythene or corrugated plastic sheets.  They look jolly robust to me.

Hi, Joshremlin, welcome to a4a  ;D
we got our skin for the poly from Northern polytunnels, they sell it by the metre, good stuff  :)

[Joshremlin]

So the idea will work ??.  It just i thought it might be a little cheaper for me and i can make it just how i need it and the size i need it too :)

the only thing i fort might be a problem was if the poly won't thick enough it won't maintain a greenhouse temperature but then what is a good greenhouse temperature can anyone tell me ???

Cheers

Made this with tilers lathes and monoflex from Scaffold Direct.

The size is approx 4Mtrs x 3Mtrs.Put 2 small vents at the rear and one above the door. It works brilliant. Already had loads of early spuds out of it. The cost of building this was less than £100.

Wow...

You aren't interested in this Allotments4all dating service by any chance? ;)

[Joshremlin]

WOW!!!   :o  :o.  looks good!! and loving the funny comment under it lmao!!

I think I might have to copy your idea on a little smaller scale though due to not wanting to loose too much space but i am thinking of doing one or two smaller ones for popping over the spuds and for the tommy tomatoes to go in :) :) - Ive got the plan in my head, hard to explain though but ill up load pictures later on for A4ALL to have a look at :P.

Although if I was to use polythene on like polytunnels which micron or what ever it is will i need ???? Will I need to change the polythene every year too ??? Plus a quick question for you with the little air gaps or what ever you call them do you still have to go down in the morning to open the door to let more air in ??? or do you just open it when your popping in a out watering etc...

Cheers

That is amazing and beautiful and perfect for winter but would a door each end with netting aid air circulation and cooling in summer?

[Joshremlin]

Im wanting to know the same green lilly because I can put money on when I get payed im off to the timber yard and making one  :) :)

[Joshremlin]

What size timber did you use to I was thinking 40mm x 40mm x 2400mm in lenth

I used tilers lathes (2"x1") in old money. Bought 2 packs from the builders merchants approx £25. The monoflex from the web site scaffold direct 3 years ago. It's supposed to last ten years. I found the vents I put in were alright but I suppose you could put more in if required. I just made this up as I went along. The frame took about 3 days including painting. I had to wait a couple of weeks to put the monofex on as I had to get permission off the committee for a structure that was bigger than 8' x 6'. Had loads and loads of cucumbers last year and loads of peppers from the other side.Good luck with your building.

When you have finished that, try this for your brassica's.
