Planning on building a lean to polycarbonate Greenhouse onto an ex-council house circa 1930s construction, roughcast down to about a foot off the ground where there's layers of brick to the ground, about 4 courses or so. I can't find anything specific about doing this, good bad or otherwise. Planning on fixing 3 battens to the house to then build the frame onto. There is an airbrick in the location that I have been advised to move, it ventilates the space under the floor. Before it's too late is there anything I should consider/do to prep the area before going ahead? I don't see it being any different to an off the shelf lean to greenhouse other than having the battons fixed to the wall. Any advice about the design/build greenhouses in general is welcome - cheers!

No advice but I'd be interested to see how you go about construction.

We have a single storey flat roofed outbuilding/coal shed attached to our house which has a south facing wall where I'd like to build something similar.

There are companies who sell lean to greenhouses, it might be worth searching for those to see if there’s any general advice there?
You can buy whole kits for about £950 or so, take that into consideration re: your budget.
Edit: my dad has a halls silverline, it’s aluminium, with a mixture of glass and poly panels. His is 10x8 (i think), and retails for £950.

The raw materials are less than half that and the finished article, done right, is generally more solid, using better materials and will last longer.

My 6' x 4' Aluminium and polcarb lean-to cost me about £150 last year. Now due to Brexit prices have gone up (mine came from Germany) but still pretty cheap.

Main problem I've had with ours has been polycarb panels being blown out - i've drilled the frame and put wire across them now to stop this happening and it's survived the last 2 bouts of windy weather.

*Edit - In fact price is same https://www.ebay.co.uk/itm/DEUBA-Lean-to-Greenhouse-6x4ft-Polycarbonate-Garden-Foundation-Aluminium-New-/131725264569 and they have UK Distributor!

I've looked at those before, but the door always seems to be on the opposite side to what i want and it's not clear how easy it is to swap it around.

Use tanalised timber from a timber yard, simple frame and buy UV stable polycarbonate sheets.

The frame is half a greenhouse and you dont need it to worry about it being watertight.

100x100mm as the frame and roofers lats make good cheap beading.

Built a big full greenhouse more than 15 years ago and its still going strong.

Not checked in here for a while, I did build it and it's turned out really well... Then some git reported it to the council and I'm having to move it as it's on the front of the house! I thought that it would be ok as it's a temporary type structure but no.

Well the bit that is adjoining the property wall certainly should be - you don't want water running down the wall above the DPM otherwise you will risk having damp in internal walls.
