No vapour barrier needed?

For all your info: this composite crap is a Class D or even Class E fire rating! I tried to burn it and it lights up like a dry wood, flame spreads very fast producing melted mass which keeps flame for a long time! Avoid at all costs on wooden structures!

Nice job and thanks for making the video. Just purchased electric mat and going to try this tomorrow on wooden flooring 😊

What size are the sheets are they 32/1000 Box Profile 0.5 Thick Polyester Paint Coated Roof Sheet

thank you so much for the videos, given me the confidence to finally order my materials and get started on my own build. much love

How close can you build to the fence and still get your metal roofing sheet on? I'm trying to understand how big i can build my garden room - fence to fence is 4.6m.

Excellent job! 👌🏽 What did you use for the soffit pls?

Great video, very informative! Have experienced any issues from not having a air gap between the insulation and the roof OSB?

Hey there! I’ve been following your channel for quite some time and was wondering if you’d recommend a similar concrete foundation like this if your ground is London Clay, any help would be greatly appreciated. Keep up the great work!

How long after installing can the roof be gotten wet? I hoping to install my roof on Saturday morning but looks like it might rain around 4pm and over night, I was wondering if that's going to have a negative impact?

As always amazing content. I’m using your video episode to build my garden room/studio for Yoga. Size of the building is 6 m x 5 m external, I plan to use 2 x 8 joists for Roof, 2 x 4 for the uprights. Our plan to have 3.6 m bifold doors at the front, What size lintel would you use for the front above the bifold doors? I was thinking, doubling up on 4.6 metre 2×9” C24 allowing 500mm either side to sit on the wall. Using 2x5 for the front wall uprights - what are your thoughts or guidance? I thank you in advance for your amazing content and the guy that you’ve given so far. Many thanks Karl

What about a floor temperature sensor?? Floor suppliers here in Australia think the world is coming to an end if you mention floor heating with timber. We use thermostats with temperature limitation ability to keep them somewhat appeased. Mention the fact that the sun shining on the floor will make it more than 27°C, they will have all sorts of reasons why that is OK🤪

Really nice build. But Jesus, poor Toby!!!!

how many inches drop of roof you did for epdm?

No, this is not good at all

This is super useful!!! Haven’t seen any videos explaining this.

Great video, very clear. Thank you for putting together!!!

I'm late to this party but just building my own room now so watching your video's repeatedly. The little details you show that others don't make these so useful, how to work out height for permitted development, angles of roof etc, I've watched your video on making a step 2 or 3 times, you're one of the few that took the time with that step. Thanks for the content, it really is taking a lot of the stress out of this process.

After a year of planning and watching more repeats of your videos the Only Fools I have just ordered timber and bought a Paslode. I have a space 8m wide, I want a 4m wide garden room and 4m for outside seating area, probably tiled floor. Can lay an 8m wide slab so everything at same height? I would worry about base plate sitting in standing water/snow or water getting under DPC etc. I thought about extra DPC at right angles outside or some corner trim, any ideas or avoid siting on larger slab?

how do you fit these when your walls are dead close to a boundary wall or other garden wall?

Hi. I’ve been massively impressed and inspired by your channel and am working through my own “creation”. I’m also going the ecoscape route with steel on the back and sides. Would you suggest following the double batoning around into the steel sections or go single? Great channel through. 👍👍

How much ballest and cement did you use?

By building the front and back walls at different heights you’ll get a sloping ceiling won’t you?

Really interesting series. Can you tell me the detail at the bottom of batten / cladding to stop wasps and other critter getting into the batten cavities? Many thanks.

With the reveals, you may find it easir to fit and then trim with stanley knife after

Excellent, clear and this will be my guide for my own project.. soon to start. thanks guys

Thank you so so much for these videos. they have helped me so much building my summer house, very well explained and easy to watch. such a likable guy. to do these for free is incredible. you are a gem.

Does this have to be done after the doors are installed or can i do it before?

Why do you need to double batten. Could you just put on horizontal battens and save some time and money?

Would you be able to send a link to the underfloor heating product you bought? I have 31mm to use for the underlay, the heating mat and the laminate and i would like to know that is the thickness of the products that you use?

How many barrows and how deep? I am doing a 4.5 x 4.5m base and am interested in how many m3 of concrete I need and how many barrows that equates to. Your help is appreciated.

Hey, love this and copied it all the way for my build. Struggling to get an extra long key? Suggestions

How much overhang of rubber do you allow on each edge. Just ordering up rubber

ain't you supposed to use a different sealer on the ends

This is such a good video, thanks for taking the time to make it! One question, what were total material costs at the time of building?

Great video, super informative. I don't know if you're still replying to comments here, but I am building with a 3.2m span (wanted an internal measurement of 3m). I was still going to go with 5x2's. Am I taking a risk? Would I be better doubling up for that? Thanks

I was told to leave a gap for expansion with the subfloor stuff. He put it right upto the wall. ?

Deffo need more than 4 screws on each joist especially on joints it will crack i use at least 6

Great video! Iv been looking into building my own and this video is a massive help cheers

how deep would you say i need for a 10ft by 6 ft greenhouse (onto a 11x7ft) conrete base please ? and a rough idea on cost of the concrete .my wooden base has rotted unfortunatly (did,nt put a downpipe on it 😐) i did concreting on a yts in 1986, but i have sciatica now which isnt fun.

Will the osb be ok in the rain for a few days before it’s wrapped Or does it need to kept dry

What do you charge to do the building? Do you have a website?

Great vid, thank you. A question - did you cover the roof only with this rubber membrane? No steel, no roofing felt? Will it handle UV over years?

Is the celling horizontal or sloping to match the pitch of the roof?

Sir, your work is very good. I want to contact you. Is it possible and how?

Do you have a link to share where you got the boards from please. Thanks

Couple questions- I have an existing base without a DPM so how do I add one which is effective? The 2.5m height rule, as I am using an existing base which is sunk into the ground at one end and not at the other (on slope) where do I start measuring from? Thanks :)

Hi great video, I’ve been following you and trying to do my own garden office . Just a quick question, you mentioned the lintel support is 1972mm high , and the door is 2m high,how would it fit in ? Am I missing something ? Thanks a lot . 7:04

Applying a rubber roof seems to be quite easy. Just one question, did you fold the corners or cut them? 0:50 ms
