That's really helpful for others! I'll pin this comment at the top. I assumed that meant they were double protected, not semi-protected! 🙈

Yep, if they were stainless they wouldn’t need the coating. Can always test with a magnet if unsure.

@@OfficeBoyBuilder Stainless are shiny non coated, not cheap but they last forever, 👍🔨🇮🇪

That's a great idea, although we were constantly taking bits in and out through there which meant we needed the access.

Did they put a soaker under the lead flashing?

Yes mate, all of them were hand cut from a roll of lead, and put in place before the flashing went down over the top.

Yeah he's definitely a rarity. He's been doing it for over 50 years!! There literally isn't a type of roof, or make of tile that he hasn't worked with.

@@OfficeBoyBuilder Looks like a man that smokes woodbines and drinks bottles of Guinness off the shelf, a serious tradesman, 👍😁🔨🇮🇪

He bloody loves a Guinness that man! Like you said, he's proper!

@@OfficeBoyBuilder I have huge admiration and respect for tradesman of that vintage. They have been creating magic with their hands for decades. We have to try to live up to them and carry on creating.

The bloke's 65 years old, he started climbing up the first ladder and got part way before saying "sod this" and scaled the outside of the scaffold and jumped over to the top lift 🤣🤯 living legend

I left that to the roofers lol!

Hey mate, great to hear you're extending and looking into options for how to go about it! I have heard people saying that too, but I honestly think it's nonsense. I think there is the chance you would receive an Extra warranty for using their boards, but how on earth could you lose your warranty for not using them? By the same token; do they specify which type of blocks need to be used in order to qualify for the warranty when rendering on blockwork? No! I used an insulated cement particle board which worked fine, and the renderer I'm speaking with was very happy to work on it, and said that the various brands of monocouche render would adhere easily.

@@OfficeBoyBuilder thanks for the quick reply and as you say it did sound a little far-fetched. Now you’ve got the building up how are you finding the sound levels in your new dwelling compared to your existing? Also a few more what I hope are myths but still worth asking. Does this type of build increase your house insurance premium? Does it effect your property value (as in compared if it were to be blockwork)? For 2 storey or more can expansion and contraction cause cracking of the render? Cost wise would it be fair to say it’s very similar? More for materials but less for labour? I don’t mean to be annoying wIth all the questions. I just don’t know anyone else who has built a timber framed extension and it seems most builders don’t know huge amounts about them! Thanks, Michael

I'm still a little early to give much of an indication on the insurance cost and valuation (as well as this idea I heard that it's harder to get a mortgage?!), Although we remortgage in July, so 🤞. Honestly I think it's all nonsense too; there are huge housing developments being done by the large home builders that are all timber frame, so I can't imagine that it works that negatively for insurance and valuations. As to your question of sound, I still don't fully know for the side bedroom as we haven't built that staircase or used that side room...The back is really good for sound proofing though - we notice a lot more noise when we open the sliding doors. The whole justification for silicone render is that it's flexible, to allow the structure to breathe with seasonal movement, so I'd hope that it doesn't crack! Cost wise, I think that getting it built for you in timber should still be cheaper than brick, not least because it's quicker, but I do believe the materials cost less too. So far this whole project has cost us around £80-90K, and I had quotes from other companies for £180k+ to do the work...!

@@OfficeBoyBuilder thanks again for getting back to me on this! You’ve given me more to think about and think I am swaying towards timber frame. Did you consider outsourcing panel making and getting it delivered flat pack? I’m waiting on a couple of quotes for this at the minute so still unsure which route to go. If you’d be interested, I can share our arcitect plans with you. Michael

Yeah I'd love to take a look! Send them to my email (in the bio/about page I think!). I did look into it, but couldn't get any real clarity on price/possiblity for just my own home where it wasn't neat/easy to merge old with new...I also really wanted the challenge and joy of building it myself

Yes you absolutely can, that's very common.

I was hoping someone would get the reference, I don't even drink beer! 🤣

I don’t think you can be a million miles from me, I saw the Brown’s lorries in an earlier video and they’re on my doorstep here in Crawley. Build is looking excellent, top job 👍🏽

Just the other side of Croydon/Surrey mate...!

@@OfficeBoyBuilder in the mid 80's I was up Gypsy Hill in Croydon doing Pirate Radio.....LOL

I used to go there as a kid to learn to swim, in the old Olympic pool in crystal palace!

Great question, and sadly the answer is "probably not". Because of the way planning works, we used our permitted development rights to get the biggest possible loft we could (just under 50m2) without needing planning permission, where they then start trying to calculate the area of your roof and work out whether you're growing your building too much. if we had done the side first, we would potentially have had to scale back side or rear extensions because of how much roof space we were adding. Or at least that's what our planning consultant advised us...

It depends what has been specified by the structural engineer, but I would say you'd be fine, and not need any horizontals. Just render board on the vertical battens

@@OfficeBoyBuilder Cheers mate 👍

It was literally just called Tyvek Housewrap...I'm not sure if there was a specific sub-type, but it's incredibly strong and very water repellent. Absolutely amazing stuff!

We ended up putting a bell-cast on the bottom to stop exactly this problem!

@@OfficeBoyBuilder ah interesting. Is it like a vented bell cast? How did to deal with stepping it out again as you mentioned in the video it was already flush with the block wall?

We didn't specifically allow for ventilation in the end, there was a surprising amount of air coming up through the slight gap that was there, so we weren't too worried about it to be honest 🤷

Hmm that's really hard to diagnose because what you've said should work to vent the air...! Two bits of advice, take lots of pictures and maybe even videos, and also check out Steve the roofer on KZfaq, he does diagnostic videos and talks through troubleshooting and potential causes of problems. Very good help!

@@OfficeBoyBuilder Thanks for the prompt reply. I'm baffled myself. Il refer to the videos and take it from there. Thanks

You can cut it with a scalpel, same as plasterboard, except that it destroys the blades faster than butter left out in the sun. The quickest and easiest way is with a mini 4" angle grinder and a diamond blade. The issue there is the noise and dust, and if you've only got one and there are loads of people cutting it, a scalpel may end up being quicker after all!

They're insulated ones that I bought from eBay. They're cement based, with polystyrene balls in them for insulation (and weight reduction).

We had a bit of wrapping spare for them to knock up their gear on.

Yes, I have put fireline board (master board) on the closest neighbors side

Just realised you're using render board 👍

Yes, that also acts as a fire-proofing for at least 30 mins 👍

@@OfficeBoyBuilder Yeah building control varies like crazy on who you see or area you're in. One person wants a fire board and another is wanting tissue paper 😂

Cheers mate. Steve and Jack are about as good as it gets in my opinion; Neither of them have ever done anything else in their entire lives, than sat on roofs and made them work. Fair pricing, hard work, and excellent results. I haven't caught up with Scott Brown recently so I'll check in and see what his method is for fitting windows. To be honest though, the guys I work with gave me a great deal for supply and fit, so I could focus on other bits while they dealt with that...and yes thanks, the sliding doors are dry as a bone! All the best with your project, let me know how you get on with it all, happy to give advice where I can on things I've learned.

@@OfficeBoyBuilder Cheers, I will do. I noticed in your birthday video when you showed the completed shell that you had fitted four electric velux windows so looking forward to seeing those go in. One question though, were you able to let the roof tile courses dictate window position, ie best placement to minimise tile cuts, or did you have to stick to rafter plan? Thanks!

You'll see that coming up in the next few videos, but I didn't pay any consideration to tile cuts when I positioned the windows. Whilst that may be helpful to the roofer (or whoever is installing the tiles) it's a bit like that tail wagging the dog. I wanted the windows in rather specific places, and spent bloody ages working out their exact positioning in relation to the room, and to one another. If I'd had to consider tile cutting too I don't think I'd have managed! 🤣🤯

I did a lot of the work, so that saved a good chunk of chance. All in our cost will be around £40K but for the spec, size and finish we've gone for it would have cost £55-60K if I hadn't done a lot of the work myself.

@@OfficeBoyBuilder WOW i just been quoted 62k on my loft/dormer after watching your vids over and over ive decided to do some of the work my self god bless you

Best of luck with it mate, nice to know I was pretty accurate with the estimate, hey! Some building firms will be fine with that, others won't, but I was lucky and found one happy to work with me

Honestly not had a problem with it... although I don't major on the fact that it's timber frame, because the rest of the house is brick built. I appreciate it can be tricky because they don't understand the building regulations most of the time.

@@OfficeBoyBuilder probably the best idea. Maybe we should take that approach in future.
