Lean-to greenhouse: Would 38 x 38 sawn timber be strong enough for frame?
It will have horticultural glass 457mm x 610mm.
Approx dimensions Width 1.4m x ridge height 1.8m x depth to wall 0.65m. I can add stifferners as required. This will lean to a brick south-facing wall. 38mm x 38mm is readily available in 2.4m lengths from Focus, where I can get a 15% discount for the next week or so. MM |

IANASE*, but gut feeling is that if you use some sort of half-truss arrangement for the roof (which will also anchor the tops of the walls and stop them from bowing) you should be OK. A diagonal brace across the side wall wouldn't hurt either, just to help prevent flexing in high winds. * I am not a structural engineer cheers Jules |

Mind you, if I could find it, 47 x 50 wouldn't be that much more expensive. I just reckon I can make a darn sight better job DIY than the commercial aluminium lean-tos that can cost over £200 for a 4' x 2'. I reckon I can do it for £100 or less. Horti glass here is £3 per 457mm x 610mm sheet. MM |

At least the Eden Clearline lean-to (an alternative product) has a decent ridge height, but it's another 70 quid, and then they want another 30 quid for the "base" - just a rectangle of sheet steel: £30 ka-ching!

I'm quite used to dowelling offcuts together end to end to minimise wastage. That'll cost me around £17 from Focus with the 15% discount (buying in packs of 4). Haven't yet worked out the total glass area, but let's say a ballpark of 10 panels (457 x 610) at £3 each = £30. Well, my lean-to is already looking vastly cheaper than the spindly, low-ridged alu-framed things on the web. The only thing they have going for them is the polycarbonate, but all I have to hope for is no hail. MM |

So I compared prices and their kiln dry sawn timber was only a little bit more expensive, so I'm using that. Size 47 x 50 approx. For cheapish glass replacement I've found a product called SAN safety glazing at £4.20 a sheet (457 x 610), but I've yet to receive feedback from the company (I always ask a question of a new supplier in order to gauge whether they are a good risk or not). However, If I used horti glass, what do you think of the idea of covering each pane both sides with thin transparent plastic? I have spray mount adhesive that I use in other work and I was thinking of the cheap plastic sheeting off the roll at the garden centre (cheap as chips), then cutting two pieces, sticking them to the pane with the spray mount, then 'clamping' the 'sandwich' into the wooden frame with lipping bezels. Or is this all a bit OTT? The concerns would be: the plastic could detach itself from the glass over time and start flapping in the wind, making making irritating noise. Or the plastic would discolour over time (how long, though?). The big advantage is the safety of having any broken pane contained within the plastic sheets. The GH is coming along really nicely, by the way. Should be finished in a few days. And vastly cheaper than anything you can buy. MM |

For cheapish glass replacement I've found a product called SAN safety glazing at £4.20 a sheet (457 x 610), but I've yet to receive feedback from the company (I always ask a question of a new supplier in order to gauge whether they are a good risk or not). However, If I used horti glass, what do you think of the idea of covering each pane both sides with thin transparent plastic? I have spray mount adhesive that I use in other work and I was thinking of the cheap plastic sheeting off the roll at the garden centre (cheap as chips), then cutting two pieces, sticking them to the pane with the spray mount, then 'clamping' the 'sandwich' into the wooden frame with lipping bezels. Or is this all a bit OTT? The concerns would be: the plastic could detach itself from the glass over time and start flapping in the wind, making making irritating noise. Or the plastic would discolour over time (how long, though?). The big advantage is the safety of having any broken pane contained within the plastic sheets. Broken panes are a fact of life with horti glass. I wouldn't bother with anything frankly. You will want to scrub it occasionally to remove dust dirt and lichen, anyway. Pressure washer good. The GH is coming along really nicely, by the way. Should be finished in a few days. And vastly cheaper than anything you can buy. I had an old Al frame, and some of its glass. The glass didn't survive being stored, and nore did half th new glass carefully transported home. there was a bolt head under the boot carpet that cracked the lower sheets from the weight of the upper. All in all the glass cost nearly as much as a new greenhouse would have. Frames are cheap. Glass is not. MM |

So? treated will last 15 years in wet soil, untreated about 2. I didn't relish the thought of working with wet wood. So I compared prices and their kiln dry sawn timber was only a little bit more expensive, so I'm using that. Size 47 x 50 approx.

I've since found acrylic 'glass' sheets 3mm thick for £4.95 (457 x 610) on the web, which I'm probably going to go for. Adds another 30 quid to the project, though - MM |

Approx dimensions Width 1.4m x ridge height 1.8m x depth to wall 0.65m. I can add stifferners as required. This will lean to a brick south-facing wall. 38mm x 38mm is readily available in 2.4m lengths from Focus, where I can get a 15% discount for the next week or so. Make sure its treated. I plan to dunk the timber in creocote (creosote substitute) prior to assembly. It's what my dad used for building a number of poultry houses on our smallholding in 1957. MM Ah, that wonderful "shed" smell. Were the poultry on a "legal high" most of the time ? They were probably overcome from the creosote fumes! Actually, that probably got 'em out of doors and eating worms instead of gorging on poultry food. MM |

MM Even horticulatural glass should outlast acrylic. The plastic gets scratched, dull & cloudy over time, ends up an eyesore. NT |
