What you want is both. Fabrication of Timberframe in factory, then brought to site. The huge savings come during the electrical phase where no special cutting away of SIP and fishing wiring through channels. I see no advantage to SIP.

Brilliant! and I'm an architect!

Use both. Wrap your timber frame in sips. No brainer

Hi, thank you for excellent video. Could I ask if it would be beneficial to have a full steel structure by adding 2 beams (and extending the window goalposts to the corners)? That would make the inner timber leaf non-load-bearing. Are there any downsides other than extra cost of steel?

I’ve had to use 9.5 to butt upto a 12.5mm before under a staircase where it was tight, I’m surprised tho the existing pb under the stairs was not a fire board although the house is 20 years old.I’m hoping the 9.5mm will do the job (it’s a slither about 120mm wide by 2.8mlomg) but it made skimming easier

Have you heard or anyone using a sips floor with timber framing for the rest of the build? Would you think there's any advantage to this idea if building a small house that would sit on a pier and beam foundation?

Hello I have a question. I live in France and the original house is a stone construction. We have a metal framed barn attached to the house. We had to dig out up to 40cm of earth in the barn to level the floor to match the main house allowing for insulation and the eventual concrete floor. The existing metal frame work for the barn will remail and we will construct a timber build inside. To finish with an industrial appearance. The metal frame will be eventually supported using concrete pillars . My question is what depth would you recommend for the foundations for the timber construction side.

How much load does the pin on an acrow prop actually take for this type of propping cheers???

Hi Jerry - I have an office to resi project in Hamilton that I am just getting off the ground and found your videos/advice very helpful. Do you & your team take on design & build work yourself anymore or can you recommend any good builders to ask for quotes?

What would you recommend please ? Thank you 🙏

Hi COULD YOU PLEASE GUIDE ME I WOULD LIKE TO BUILD DOUBLE EXTENSION 🙏 THANKS

So many useful tips 👏🏻 subscribed

What's the benefit of using tongue and groove chipboard over osb boards? Osb Is usually cheaper

Excellent video. Have done, more or less, what you've advised on a new floor as part of a whole-houose renovation. A couple of months after finishing and when loading floor with 10mm laminate flooring, partitions, cupboards, etc terrible squeaking started. On 600mm centres, I-joists, using D4 Egger-type glue and screws with 22mm caberboard. Still have 'access' to joist-board face from underside. Any suggestions to cure this nightmare short of knocking the whole house down ? :(

Another excellent video on the laying of chipboard flooring! thanks for all the tips and hints - keep em coming :)

I did not find this video relevant or useful for 'setting out foundations'.

Our house initially had flat roof and therefore the insulation is between the ceiling joists. Later, pitched roof has been added on top. It's a single story house and due UFH we wish to raise ceiling - thinking of exposing joists and have plasterboard on top. What would be best method of insulation? The roof cavity is ventilated. Note that we also want to install MVHR and ducted AC systems which would interface with the ceiling. Also, the lights would be fitted in the plaster board too. Would it make more sense to do warm roof insulation and reduce roof cavity ventilation?

You don't put a sheet of visqueen behind the sleepers? In Australia, we now have to put a sheet of cement board and plastic sheet behind the wall to prevent moisture breakthrough , even with conrete sleepers. Also, our posts have to be same depth as height. Absolute overkill but that s what the engineers want

Those three joined beams are making me whince 😬

what you save by doing it yourself youll spend on wallpaper

Thank you for your great expertise and videos. Got great insights in planning and execution.❤ from India

Great video, I’ve been installing sip kits for a while and I’ve noticed a lot of people wanting to build out of sips are looking to make green homes, ultra modern homes , energy efficient and make them air tight etc

Ive just come across your channel and you're making some of best property and diy content on KZfaq. Videos are well thought out and informative. Thank you.

Great video thank you.

I just think in your video you do need to be careful how you worded things as I think you are talking about doing electrical work in Scotland. Yes the Electrical Regs are the same across the UK, this is where it ends though as Building Regs are slightly different in other parts of the UK. Work that is notifiable in Scotland can be slightly different than the rest of the UK and they require a warrant to be completed in Scotland by the installer as well as the certificates. It is always best if your unsure to contact local building control as to what is required. As for the technical side, you maybe should have mentioned that you also needed the electrician that is signing off the work to design the circuits; and that he has given you your cable shopping list. On the Insurance side anyone that is attempting to carry out the work and thinks that you can just get the Electrician in at the end to just do the testing and issue a certificate, you will be lucky as they are legally carrying the can for your work and probably will not do it. Not involving an electrician from the start of a project will most likely void your insurance if the worst was to happen. That is not the case here from what I've seen in the video.

Where can I learn about in Georgia state?

Thanks!

Hi, I’m about to build a workshop in my garden (timber frame, insulated and clad), and I’ve looked at other peoples builds-sheds, garden rooms etc. I noticed a lot of people are using 4x2 cls but with 400 centres in the wall studs. In your video, you say you are using 600 centres. Any idea why people are building garden rooms with 400 centres? Are they over engineering or am I missing something? Great video by the way 👍

This video is depressing. so much bureaucratic BS! uk looks like communism. the thought of it make me feel sick. now they have "building regulations approval" seriously? humans have been building shelters to 2 million years but suddenly all that s**t is "necessary". So glad I don't live there!

Thank you!!

Hi Jerry. How do you fasten 50mm insulation externally over the studs? How would i then fasten render board over the pir? Im assuming I'll need some sort of DPM between render board and PIR. Thanks again.

Cavities were always airtight and sealed at the top, its the way we were taught at college in the 60s and 70s and were always built like this.This only changed late 70s with the advent of cavity insulation which had to abutt the roof insulation.

Thumbs up defo - another excellent building tips and best practices video thanks for sharing

When you say Building Control will 'insist' on a Structural Engineer's report on foundation design, is that just applicable to Scotland? I've never heard of such in the rest of the UK.

What would you use for a first floor bathroom with a picture roof ????

you want the perfect job, you have to pay the perfect price" you only get what you pay for" like everything else, there is a right way to do brickwork, and there is a wrong way, always check out your bricklayers"

Are architects terrified of being sued now so they over compensate?

How are you avoiding vermin ingress below your floor level?

Thanks for the great videos. How do you fix the walls to the foundations?

This’ll be awesome when it’s complete. 👌🏼

I have no experience in the building industry. We're about to start a single story extension and whenever my wife or I wonder how does this or that work with the build process your videos have given the exact answers on multiple occasions. Thank you very much for sharing your experience and info 👏👌🙏.

Some excellent and very valid points made here, I couldn’t tell you how many arguments I had with supervisors over strongboys before I worked for myself, they have their very limited uses, such as supporting new lintels for a very short time, but anything involving major structural alterations has to be needled. Also, cavity trays are essential for lintels, areas of higher ground level against the building, and of course at abutments. However, I feel that they are sometimes specified needlessly at floor level and do more harm than good. Depending on the ground level and conditions, I feel that in most situations a standard dpc is the best thing. Just my opinion and you may not agree but I do think trays have a vital function but only in cases where they are necessary, and aren’t a fix all for other issues as some architects seem to think.

Is the outer leaf not tied to the inner?

And if you make any mistakes it’ll cost you a fortune to correct. If you think it’s expensive hiring an expert, it’s nothing compared to how much it’ll cost you using a novice

Thank you

Hi very informative description of the works, excellent, just wondering what software you use ??

Hi Jerry, forgot to ask - how air permeable is OSB 11 mm, which you mentioned in your earlier videos? I am planning on using high density mineral wool insulation (e.g. Rockwoll) for better sound insulation (planning to use the gardenroom as a woodworking workshop and I would like to keep my neighbours happy :) ) , over thermal performance offered by PIR. Will fixing of OSB over the outside of the studwork, provide a chance for the moisture (seasonal and from gradual drying of the timber) to escape through OSB and leave via the breather membrane? Thanks again.

Hi Jerry, I am really glad I found your channel. Lots of practical tips and very logically explained. I am in the process of building a small garden room (~9m^2) near Glasgow. I was wondering how do you go about supporting the 4 corners of the flooring (e.g. kzfaq.info/get/bejne/i7VhfKSnmNnSpY0.htmlsi=8gqjWhF-C93twD-9&t=368)? Is it a good idea to offset the the perimeter joists by a bit (~20 mm) to allow for fixation of the chipboard, but still provide the support for the bottom plate of the wall (with the created opening to be filled with PIR insulation)? Thank you. Keep up the good work!

Very good detailed information👍🏻

Really helpful points. On the last point about cavity trays for walls adjacent to a monopitch extension, what about in traditional buildings/older properties where there is a solid masonry wall with no cavity? Are there any precautions to consider?
