Garden room / posh shed /workshop build log

I think in his solo build video he did. TBH the main thing is being ready to secure it - so have an offcut of 4x2 with 45s cut into each end, and the screw mostly home in the right face of it lol.

It didn't move nearly as much as I expected - I don't think I toenailed it or anything, but I believe that is the "official" way, i.e. whack a nail through it so it can "pivot" and not fall backwards.


1:10 but obviously half the size!

If you think it's too much, you could "chop" the fall and do it in two halves.


Funnily enough I just watched that! That's the main miniseries I'm going to watch.

I'll try it on the 7metres, got a few hop ups I can put under it.

Where I've got my 4.8m lengths on the header wall did you add a double timber to support it?

Any issues from the neighbors? :D

Not yet..... Altho I am going to go slightly over the permitted development (circa 2.6m in height) so here's hoping even if there are issues id have planning accepted (over 1m off all boundaries). Gonna have 200mm extra headroom over the build pack and doors I've ordered are 2100 high.

I realise fitting the back wall and overhang and gutter is going to be a pain in ass!

@dlockers did you cut your boards flush with your frame or allow a small overhang to stop the OSB clashing with the wall?

Looks like to stop a clash would need a 2cm or so offset if that makes sense. But realise with walls over 2.3m and 100mm floor beams the 2.4m OSB probably won't hit it anyway.
 
Extra 10 on doors is worth it. The 1950 ones I've got are noticeably low. Not ducking height but not far off lol.


Not sure I fully get you - my OSB is flush with top of wall, and extends about 5 inches passed the end so it overlaps the bearer/metal washer.
Yeah I thought generally the whole idea seems a bit low for internal head height to be honest. I guess it's so the people selling them don't need to block themselves with planning but if doing DIY can either sort the planning or take the risk.


I'm talking about this overhang of the floor sorry, how much past the floor is yours? (if at all?)

Made part of the wall and need to put horizontal battens on then lift it. It says to screw the osb3 to the wall every 300mm which seems crazy amounts of fixings (especially as the battens will further tie it down so I've done far less

I was thinking for horizontal to only put 4 or so battens to support this. Seems it only needs every 1200mm anyways


I've split the long wall into a 4.8m length and 2.3 ish length.

Did you think about putting fence panels along back and right hand side ? When shed is up I can imagine it's gonna be a pain to trim those hedges.


They go right along garden so no
Looks good - makes sense to split the wall. I've gone for similar cladding and from what I can read they recommend just doing horizontal. I think I prefer lining it up and doing vertical tho, to stop any water. Did you overlay the Tyvek correctly? A bloke posted the other day and he'd do it to feed water into the structure lol.


They say just about horizontal for a couple I've seen but surely that risks standing water behind it? Can't be any risk if you can fit vertical.

When you say correctly what do you mean? I did bottom first then a significant overlap (as its longer than I require.)hopefully that's right :D

Yeah I am with you - going to do it vertically and line up with the metal fixings.

Correctly - as in, when its stood up, the overlap means rain will drip from top to bottom and not go from top sheet, behind the sheet beneath it etc. Imagine cladding but clad upside down :cry:. I think it is an easier mistake to make when it is on the floor!!
Oh aye done the bottom sheet first so should be sound (at least I hope I have!!)
 
Glad I made this wall in half's, needed the wife to help me lift the 4.8m section

Couple qs mainly for @dlockers :

I am slightly out of plumb on the outside of the built corner but the inside is Bob on. Presume that is due to something wrong with timber? It's inside the level bubble so preshme it's fine.

I made a mistake with the OSB in that corner so had to make a slither end on the back wall rather than tie it to the adjacent wall

Also a dumb question..... Is much of an overhang required at the back (presumably mainly so it passes your cladding?) and do you even need a gutter if you have an EPDM roof?

Going to be a bit tight here

Looks good! I wouldn't worry about being out of plumb unless it is seismic. On the rear I wouldn't leave any less than 15cm, and I'd definitely use guttering to move the water away from the main structure. It sheets off but then hits the floor and splashes up which is what erodes the ground. A gutter delivers the rain gently to the floor
Ah yeah that makes sense about the gutter thanks.

Why do you think 15cm? I was thinking the 50mm to overcome the battens plus say 50mm which will be more than the sheet cladding. Then whatever a gutter is.

Also think I've ****** my hands up/given myself carpal tunnel, hopefully it goes away when I have a break!
 
Got my final wall built but will need some help to lift it, especially as it's now soaked up a load of rain!

Cut out the openings for 2* 600mm wide by 2100mm height windows and made the steel wall for the French doors (opening will be 1900 wide by 2100). Before I put the windows in I'll cut the base plate so the windows align horizontally with the door.

In the end bought a 2.3m steel for 140 quid which seemed quite good.

Definitely not an issue. Looks good man! For the steak I managed to handball it, just have a step ladder to tuck it through
I went for the Oakwood "ladder" way to lift the steel. Felt quite easy so yeah could probably do with just one set of pins or my taller ladder.

Also the build pack 200mm leaves **** all room for the tech screws to the steel from the bottom.

The rip on the steel I've slightly ballsed up and it sits lower than the steel but guess it doesn't matter

What do you think for this detail on the breather membrane. Does it matter if I get a 3rd sheet going right to left to cover the gap?

Just get some 150mm structural screws and screw up from below, its more than enough and will negate the need for hurricane straps. As
I put the roof beams in today and there's multiple 100mm screws (4 to 6) in each beam. Should be fine.


I think you already replied @dlockers on fb but this is a weird detail I think you told me about.

The gaps make sense to fill with PIR but even the blocking is only 2" thick rather than 4". Suppose if you use 50mm PIR the heat loss would be pretty similar.

300mm overhang is very close at the front to this tree!
