1930s Semi Refurb - Part 11 of ... (Summer House)

Yeah, you'll have to cut some no matter what - unless you use fittings to get the drop; but that cut seems even worse than just using the chop saw lol.
 
Ah do you cut the front end vs the back end to get a fall on the "flat" roof and work out the differential on the timber walls in between?
Yeah front and back have the fall. Sides aren't supporting anything so just cut to the smallest height (generally the rear). Then when you clad in OSB you can cut the fall into it/snug to the roof. Roof joists run front to back so sides are just holding it square.
 
Physically or financially? :D... Or both
Lol both man. My hands are crippled. Heading to Portugal today so pausing for a bit :rolleyes:

Really enjoying these threads, is kind of giving me inspiration to tackle the jobs around the house we bought back in December - but I'm a complete DIY novice! I'm between do it yourself and save on the labour, and you'll definitely regret trying to refloor downstairs after you start and mess up within 30 minutes.
A mistake I used to make was letting the pressure get to me. A lot of jobs are rushed by self inflicted deadlines etc. Nothing worse than midjob contemplating how you'll do it better next time :cry:
 
Can I borrow it? Least you could do since you started this thread and filled my YouTube with garden room build videos.

ETA summer 2025!
Haha it was a borrow from my brother in any case.

Some tools are stupidly expensive. Going to be hammering nails in manually for me like in the old days.
I wouldn't dream of screwing this. Screws aren't as good for a start, cost way more, and will ruin your hands. Even if you just do a rental whilst you built the walls it'll pay for itself many times over.
 
Why would they ruin your hands? (to be fair it's a lot of screws!) id have thought will be OK with an impact driver?

I'm probably not going to buy a 1st fix nailer as my dog is scared of the noise from nail guns :X. And instead manually hammer/screw it.
Holding the screws to get them started. It's all fine but basically a cheese grater by the end lol. A proper paslode isn't too loud, it'll save absolutely ages too.

I'll probably have a week off work when I do mine. But floor, 4 walls and roof, think will need for a week at least.

I'm concerned about using screws tbh, not because of the strength but because of splitting the wood. Even the tiniest of screws I use at home seems to split the wood if I don't pilot hole it. 6mm structural timber screws at 150mm-200mm long, could ruin every timber I try to drive into.
Yeah I jest a bit. It's taken me what, 9 days to get to the stage I'm at? Joist hangers are a **** take for time too.

The 200mm screws comment was that welshmans comment for incorrectly strapping the roof (imho. They make hurricane straps for a reason). You'd only need 100mm for normal construction.

Interesting dilemma on the screws vs nails.
An unheated outdoor space I would probably lean nails because the wood can gain/lose 7% in length (width, height) etc depending on orientation as it absorbs and looses moisture.
The general rule is screws when you don't want something to move, nails when you want to allow movement.

If I was building something like lockers I would put skylight(s) in, we have one in our gazebo (with shuttered sides) and it lets loads of light in.
Nice to go into when its raining, shutters down, and sit with the rain pounding down on the skylight.

They arent expensive for outbuilding type stuff. Let a lot more light in than windows unless your going to put windows all round.

Id absolutely love skylights but I just can't risk getting the 800quid rubber wrong. Maybe a future thing as it'd definitely be a winner!

Do you think it's feasible to build something like what dlockers has done here, using hammered in nails? (Not gun)
Yeah watch oakwood..he did a whole build hand nailed.
 
Never had an issue with screws messing my hands tbh. Like I said impact driver will get them in single handed. Built several outbuilding, summer houses home offices all timber framed and never used nails. I'm a screw guy, I love screwing.
Yeah but I've got hands like Lenny where as yours are probably like the bottom of my feet.
 
Thought the damage to hands was the torque, or recoil from the gun - RSI ?, not callus's, but doesn't the more expensive kit have less kick-back.
(so the guy who overtightens my wheel nuts at kwikfit is probably fine)
Hands are mashed because of CTS. My comment about mashed hands from screws is mainly from spax floorboard screws. If you Google them, they're threaded bottom and top not middle. So I found myself holding middle, but as soon as you screw your basically holding the top thread. Gloves fix it obvs. I'm just being dramatic.
 
Most decent screws nowadays have a sharpened point so a little pressure will mean they hold where you put them anyway

I thought my accountants hands were soft* but never had issues with screws, but maybe those manicures lockers has keep his baby soft ;)

*actually lots of allotmenting mean they arent that soft really
It's those bladdy spax floorboard screws with serated edges. I'm into edge cases of nice to have tbh I'm not that much of a pansy to not like screws. Just given the choice on a project like this it's a no brainer in terms of time saving.
 
Sorry that things have got a bit heated here, however I appreciate having seen multiple methods to tie down the roof as this was the part I was most unsure about.

I find fixings a minefield in general. Its nice to see what alternatives are available for different applications and its also useful to have exact specs for things. Too often the advice is to use nails or screws but with no specification of length and width dimensions.


@dlockers I was watching the Oakwood Garden Rooms build last night, where he does it solo and with only basic tools. Very useful series. I think their 'build packs' are very expensive though (now £130) for what is essentially a parts list but did you find it useful? I noticed he intended to use a nail gun but forgot it early in the series so proceeded without, by separating the nail gun nails and using them by hand. I would not have known that could be done.

Thinking about hand nailing in combination with a screw to pull the joint tight first. Its only 4 nails per upright, two top, two bottom which on a 16 stud segment will only be 64 nails. Obviously plus a few extra here and there, but certainly not many really.
Just be mindful this chap recommending screws has not built anythin like this, and is preaching guidance from American house builders who talk about 'following code'. None of his examples are UK garden rooms. A strap is still the preferred method as it's impossible to fail, and judging by some of his comments they tend to required a roof joist to align with a stud. Read some of the comments on the videos he shared and you'll see lots of folks saying the inspectors don't care what the screw company says, they want it tied down with a strap (10 nails at 90 degrees vs. a screw perpendicular to the force).

Also he is quoting Americans with pitched roofs where they use single joists (not double like a 3.5m span requires) and line up with the studs to carry the load to the floor. This would give you inefficient spacing on a double joist setup. Also, double top plate is to build a house not a garden room. In a structure like this it'll just create a cold bridge unnecessarily. In fact my professionally made 13m x 3m pitched roof workshop only has a single top plate.

The build packs are worth it if you don't want to waste time planning materials. I essentially sent his kit list to my merchant and it arrived. I didn't think twice about quantities. It also included some extra nuggets on specific dimensions and rod spacing but with hindsight is all pretty easy to work out yourself. If doing it again I'd possibly back myself now, but given I took a week off work to squeeze it in, I didn't want to chance any errors that'd take days to rectify.

When he stripped those nails - that was a bit of bodge. He'd just forgotten his actual nails so was scavenging some. I wouldn't recommend it - like you said, they are a fraction of the thickness and unless you're a dab hand at hitting straight, you've got no chance.

I used a few 100mm screws when framing if the frame was too twisted for my strength to hold it tight. You don't need to screw unless you have the same issue. Screwing and nailing everyone is overkill.
 
Yeah Im going to build the floor first obviously, then the four walls and lift into place.

My tightest wall will be the back one, as I have to get it really close to the boundary fence (narrow garden). I'll be making this wall in a complete piece including the cladding and then lifting the whole lot in one.

I'll need to find a cheap lightweight cladding for this back wall, it will never be seen so I just want something easy. I'll be using something nicer on the other three walls.

On the Oakwood solo build video the guy shows some good tips for getting things straight, using screws to pull in a gap, and solo lifting beams by attaching temporary bits of wood.
Just be mindful on spacing - you'll need 150 overhang all the way around, plus fascias, plus guttering. So don't go so close to the boundary you end up with stuff overhanging in their garden!

I assume you've seen the few vids where he finishes the wall before lifting it, due to space issues?
 
150mm overhang is probably going to be too much for me on the back. Ok on the other sides. At the back I will have to make everything almost flush. Im thinking of sloping the roof side to side rather than to the back, so that I don't have to have guttering on the back at all.
Almost flush will be a disaster for water.
