Enjoy your series of videos. These are good for trades and designers that don't get out to site much. As a self-employed architectural technician, I specify this type of construction on ALL of my extension jobs, this has been a method of construction in Scotland for as long as I can remember. I design things slightly differently, but there are several ways to construct, as timber frame details vary. I noticed you have double cripple studs but no full height stud at wider door opening. One thing I design differently, is the lintol over the side door, I put this at the top of the panel below the double header, simply in case the client changes dimensions of windows and doors changing the head height, easier to change infill timbers than to relocate lintol !!! I would also show noggins (dwangs in scotland) at edges of sheathing/flooring, spec of rigid insulation has to be high for U-Values to be acheivable to regs. We have calcs done for U-value and interstitial condensation. Good to see the progress, keep up the good work.

Hi mate great video, If your attaching a kit to a brick wall you can cut a stick to the size of the kit, Staple dpc on back and level it and pack it to suit Bolt it on,. Then you can take an accurate size from stick to the edge of the building and your not trying to a hold a frame and level it.

Awesome to hear mate! Best of luck with it. Let me know if you want to soundboard anything or ideas, happy to help/give my thoughts. We split our planning in two because of the size of the dormer and the size of the rear roof on the ground floor extension. Our planning consultant (linked to the architect and structural engineer) strongly advised splitting them into two, the loft as Permitted Development and the rest as householder planning. It went through fine like that.

This is brilliant, watching as you go on. My only question is, why don't you remove the pebble dash render first? We're looking at starting our extension this year, I was going to do the same out of timber, building the majority myself but due to a new disability, I can no longer do this and have to get a builder in! Brick & block but hey ho.
@OfficeBoyBuilder
@OfficeBoyBuilder 3 жыл бұрын
Thanks mate. Really sorry to hear your plans have go awry slightly with the build... hopefully you can still be heavily involved though. I was in a fortunate position that our pebble dash is very solid and can be rendered over directly (not always possible when it's flimsy or old) and internally we can dot and dab over it with plasterboard. I removed it in the sections where I thought it was needed in order to get a secure fixing between the timber and the walls.

@OfficeBoyBuilder

We've been framing out in 6x2 (150x47mm in new money). That gives enough space for the airgap and insulation requirements, and strength for 2 storeys of building.

question im looking at building my own timber frame extension. very similar to this. when putting your timber frame together do you just use a nail gun or timber lock? i understand why and where to use the chemical bolts. but unsure of when touse the nail gun and when to use the Timber lock. thanks
@OfficeBoyBuilder
@OfficeBoyBuilder 11 ай бұрын
You would generally use nails...they are strong and much more flexible, which is really important in the building, as it will need an amount of movement over time. It's also a hell of a lot quicker with a nail gun than using a noisy impact driver and timber locks.

9:52 is that insulation pushed to deep in the stud? I’m worried the gap you create when you put the vapour barrier on will condensate?
@OfficeBoyBuilder
@OfficeBoyBuilder 3 жыл бұрын
It is pushed right back against the outside skin of OSB, creating a slight air-gap inside the room (between the insulation and the vapour check barrier). The airgap internally was specified by the structural engineer, so I'm guessing the risk of condensation is minimal. The moisture should be stopped from the outside by the membrane on the OSB, and the vapour check barrier on the inside stops moisture/condensation from the inside of the room.

I’ve seen people with condensation problem with flat timber roofs, how will you avoid that with your walls?
@ComeWhatThey
@ComeWhatThey 3 жыл бұрын
Condensation generally occurs with older style "cold roof" construction, with either no insulation or insulation between or under the rafters. Modern flat roofs are "warm roofs" with insulation above the rafters so they don't get cold enough to attract condensation.
@OfficeBoyBuilder
@OfficeBoyBuilder 3 жыл бұрын
That's true about condensation, so you use a membrane to ensure there's no moistures transfer on a warm roof. You can't build structural walls using warm roof techniques because rigid PIR doesn't hold much weight, meaning you have to insulate between the rafters. With a depth of 130mm between the studs, we have great density of insulation, and 170mm between the roof rafters (+40mm superquilt on the inside AND outside - that's coming up in another video). So long as a cold roof system can ventilate over the top of the roof, and you have a vapour check barrier, the chances of condensation are very low.

@@OfficeBoyBuilder I'm binge watching your content at the moment. Your presentations are very good, very clear and concise. Your work is tight and you take a belt and braces approach. I'm a disciple of over engineering things, 👍😁 You went with a single bottom plate on your walls. Technically if the wall is load bearing the top and bottom plates are meant to be doubles. That said you have stacked your rafters over your studs and your studs over your joists so weight is directed through the framing to the foundations. Again these are my observations, not criticism. I have subscribed to your channel so I will be getting notified of any future videos. That's what YT is such a great medium for tradesmen, we can share knowledge, 👍 😁 🔨 🇮🇪

I was really interested in trying Advanced Framing techniques from the states, building the studs and joists and rafters all in line so loads are directly transferred, as you've noted, except with Advanced Framing they build at 600 centres. My structural engineer said "no" in as many words, but I still tried to use the technique just at 400 centres lol.

I believe it is cheaper...not specifically because the materials are cheaper (all the timber for this build was £9k) and because the cavities are thicker than brick you spend a bit more on PIR insulation which costs more than mineral wool used between brick skins. But it goes up quicker for sure, and with time equalling money, I think it's cheaper (and more efficient)

@@OfficeBoyBuilder Why can't you use mineral wool with timber frames?
@OfficeBoyBuilder
@OfficeBoyBuilder 3 жыл бұрын
Good question! It's because of heat transfer, cold bridging and the insulation properties of timber and mineral wool. When you build with brick, you have more thermal mass because if the density of the block work, so with a 100mm cavity you can get away with using mineral wool, even though it's not as efficient. With timber frame (be it a loft conversion or a house) the thermal mass of OSB is much lower, so all external walls need rigid PIR. That being said, rigid PIR is far more efficient, so although there's more thermal mass with brick and block, it's more efficient using timber and PIR. My walls are around 70mm thinner than a typical brick and block cavity wall, but are far more efficient in insulation terms.

Good point, but not in this instance. I'm running all my own electrics, and working with a sparkie to get them all done by the book. But I'm also running a slim internal service void in my walls on the inside of the room. I am going to counter batten the internal walls, run my cables, and then plasterboard over the top of them. That way I don't affect the insulation or the integrity of the vapour check barrier.

@@OfficeBoyBuilder thanks for replying, yes makes sense if you’re counter battening. I lived in Canada for over 20 years as a carpenter and this is the way we build over there, so it’s nice to see a place over here being built that way . We always build the subfloor first and then build the walls laying down on a nice flat and level floor, that way you get good fixings through the sill plate and top plate, then sheet the walls, then stand them up and then brace them, it’s a lot easier and more efficient . I’ll be looking forward to seeing the rest of your project 👍
