How to build a huge garden room roof with a canopy
HTML-код
- Опубликовано: 9 фев 2025
- This roof is huge! and has 75 5x2's in it, including the front wall.
Flitch beams are added for extra strength and double timbers bolted together makes a solid roof construction.
over kill ? or over engineerred? what ever you decide, I know the customer will have no issues.

YOUR BACK! OMG incredible. Thank you guys keep them coming please
Really impressive Liam. Don’t ever stop showing these
Really want to see more of this build. Makes a change from the usual shoebox at the bottom of the garden. 😉
I can only build what the customer wants mate
Absolutely. Will watch whatever the size is... That's what she said.
😀
Welcome back and what a build!!! Can’t wait for the rest of it. Keep up your amazing work Liam and team
Your attention to detail is second to none mate.
Liam you inspired me to build my own. Thank you 🙏
"I lost one across the garden then" 😂
Great vid, valuable info. I'll watch the canopy section a few more times to get all the details from your rapid fire style (you're faster than a Paslode)
No joiners we’re hurt in the making of this video, 🫣they were all hiding behind the build 😉
this has to be the most interesting video you haev done to date - cant wait for the next installment.
Not sure how to take that 🤣
Amazing work and brilliant video. Feel proud about this one. A nice 150-200 oak beam support with swept knee braces would look pukka.
Can't wait to see the cladding 👍🏼
It looks like this guy likes his job. Im happy for him
The metal shop that supplied my flitch plate for me stagger drilled it for me - he said you want 10mm staggered - I said aye - so worked well, I made an arse of drilling the wood , now I know how to do it for my roof 😂 thanks
Looking very well thought out 👍👍👍👍
Thanks for that, quality, looks like a bigger front to back than you normally do, might be wrong , like the double osb idea
Outstanding again 👏 👌
I’m currently halfway through my Oakwood garden rooms inspired build but I refuse to buy a nail gun just for it so it’s all being done my hammer 😂 thanks for all the informative videos over the years!
Watch your fingers, my nail never grew back properly
@@thegardenroomguru we used to have an old frying pan to give to anyone who hit their thumb with a hammer so they couldn't do the same thing twice :) Great video as always Liam.
Not sure if you have tried it before Liam but we recently had to insulate some walls and floor in a garage conversion and we cut the insulation over a table saw with a good extraction and it worked a treat as we make all the stud studs exactly the same and slotted the insulation in perfectly. It made a nasty job easy. Obviously the depth is more of a issue on the thicker insulation.
I’m waiting on the genius that is Ronnie coming up with his dragons den take my money solution for cutting the 100mm 😎👌
@@thegardenroomguru give it a go mate I’ve always cut it by hand and it’s a nightmare! And spent two days coughing up the crap even wearing a mask.
I will mate, everyone hates it, I especially like how when you think you survived it, you rub your eye a bit later, and it left a little bomb on your eyelash, that goes in your eye, and it gets it’s final bite at your soul
Wow, a fab build
You exhausted me!
I drilled 24x 12mm holes in 10mm steel with a Titan 1500watt electric drill and one Dewalt 12mm all material twist drill. I also used WD40 drill oil. I am sure any drill will do, it’s all about the pressure you can apply plus a slow drill speed.
Impact wrench will be better for tightening them bolts, no more snapped adaptors, impact drivers are getting more and more powerful and tend to snap hex adaptors 👍
Amazing work!! Please put the guard on the grinder 😮 Rant and rave that they can do what they want. I know that. I've seen a few blow up it's terrifying, that's with a guard on. You just hope no one is around when it dose. Sites I've been on even if you think about taking the guard off your feet would not touch the ground, your off the site. Even guys with 15-20 years service. We all know it's easy without the guard and this is the "real world" etc. But when it goes wrong and you twist the grinder by mistake... Well someone could be going home with one eye.. think about it and keep safe guys. I've been in the nuclear industry for 10 years and safety is drummed into us everyday..nothing wrong with keeping workers safe. Much love and keep up the amazing work guys!
Absolutely love your videos building garden offices. Watch them all I reckon now. Very informative. Wheres the best place to purchase the fascia boards?
we get ours from northern building plastics, but might be changing to GAP
Brilliant video and explained. I'm currently planning how to build mine and how to build the roof. I were hoping for a 5x5.4m span. Covered with the 50mm insulated roof panels. You mentioned for your own job doubled 5x2s would be fine for the 4m. Do you think doubled 6x2 would therefore carry ok at 5m please? Thank you 👍
Hi Liam fantastic build I’m looking at building one in my garden 5m x5m with a 2.5 canopy would two 5x2 bolted together be sufficient to span the 5m gap or would I need to use flitch beams or could I get away with 6x2 bolted together thanks
Videos are a goldmine of information thank you so much for sharing ❤
Brilliant great to watch atrue tradesmen and agreat team
Hi Liam,
By doubling up on roof timbers how much extra span does that permit?
Cheers
Just to say, after speaking to various planners regarding the height of a garden room i was informed several times, that the max height you can go to is 2.5m unless it has a sloping roof which then becomes 3m at the highest point so that if the roof slopes it can slope up at the back to 3m in height. correct me if im wrong.??
What thickness osb do you use on the roof? Can you go with 9mm or does it need to be thicker. Also, is 2x7 OK for that span as a single joist? Ta
Great video as always Liam, I learn at least something new on every Video, thank you. got a question that I may have missed, but was wondering if you or Jen could shed any light on.
QUESTION: In previous videos I see the mention of how important it is to use upside down Joist hangers to hold the roof down. In this example with the doubled up beams I cant see any joist hangers? (maybe they're hidden by the OSB?), what approach do you employ to stop the wind damaging this roof if you didn't use Joist hangers?
Thank you in advance. Keep up the great work team. Brilliant stuff regarding the flitch beams to.
Wonderful Work. You mention you are using the wrong size bolts - what is the right size bolts for those Flitch Beams?
Hi liam great video as always mate just one question does the canopy get counted in the overall square foot under permited development?
Inside floorspace measurements...
no mate, its livable usable space only
Just a quick question, with it being 28 m2 is the 'ruling' it has to be 1000mm off the neighbors boundary if combustible material is used?
Great build as always, cant wait to see it finished cause i think this one is the perfect idea for myself.
We are approximately 1.4 on the side and 1.5 on the rear mate
If you're using 20mil quazi bolts to support the flange bracket of the 4x2 rods, do building regs allow you to use timber bracings when it's load bearing?
Hi mate, I need to cover a 7m space so will add a flitch halfway. Can the steel between be made up of two pieces (width is 5.5). I will of course bolt the connect in the middle of the beam or does the steel have to be one piece? The beams of course will be two full beams
For the 4.8m timber (canopy) that you've joined to the roof timbers, how have you joined it? I can see hangers on the actual canopy bit. Thanks!
Im on starting a build based on what you do.
About to build the walls. Will be 11mmosb outer with rhino ultra but one question.
Does the wall CLS need to be treated timber or not.
Great stuff! About to start my build soon with the pack. What's the maximum unsupported front overhang you can get away with on the front with a 3m depth build?
I wouldn’t go more than 800 tbf mate
If you're using timber column supports for the canopy, what size and spec would you use?......I thinking of doing something similar once I've flattened my asbestos garage
What happened to your little finger Liam?
Great video btw !
Dislocated it mate, fell over at home 😬
What's the base construction on this build Liam, concrete or rods?
rods mate, I've got a build pack for this size on rods and one on concrete
@@thegardenroomguru thank you. I'm going to purchase one of your 6x4m packs BTW, you're an inspiration to us all, keep up the great work fella
@anbridale thank you mate
Hi Liam, this is fantastic. I’m in the middle of my massive build of 7m x 7m and doing this with permitted development. Did you have to get a structural engineer to do roof weight calculations. Btw I went for giant ground screws for my foundations and currently framing them. Wish I could share pics with you. This build inspired me cos it’s one half of my build.
How is 7x7 under permitted development?
Would love to see a build this big !
@@ryanhovells2339 There's no size limit on PD, as long as you don't use more than 50% of the land. Anything over 30sqm has to go through building control though, so proper foundations, fire regs etc. The equivalent of a new build house.
If you were to have a canopy on the other side, making it symmetrical, would it still come under permitted dev, as there's still only 28m/s of internal space? Cheers
yep, its only the internal that counts
Thanks for the info
Another quick one hopefully: What constitutes it being a canopy? Can it have a solid back wall but be open on front and side? Cheers
What size timbers for a domestic 4.8m roof?
What are the joist hangers your using on the canopy roof timbers, not upside down as usual?
I wonder why so much heavy support is needed for simple roof sheets?
what area do you cover mate I'm in bolton
That looks epic! Did have to go 1m away from boundary as well for building regs?
Couldn’t you do a 6x5 in this method and get exactly 30m2?
Is the steel plate painted? If not it will corrode and blow out in a few years. Top job apart from that
How much you charge for this kinda build? Looks amazing as always!
not enough is the answer for this one mate.
Hi Liam
Great build yet again, can I ask why you haven’t been using the insulated roof panels?
Customers don’t like the look of them mate
Going to order your 7m x 4m build pack next week. Glad you mentioned about the double 5x2 being sufficient for 4m span. I was hoping to go 4.2 and still be under the 30m2 internal floor space. Would it be risky though going 4.2m with double timbers? Very informative as ever though. The cost for the metal is already a concern.
As said on the video, my own garden room? I’d have no issues doubling them up. Even at 4.2
@@thegardenroomguru That’s great to hear.
I'm not sure the match the span rables for calculated load though. You could probably go up 50mm in roof beam at C24 and meet the span tables and be away with all the steel. Then you could have 120mm noggins, vent soffit front and back and have the insulation in the correct place and a have a true vented cold roof.
It's probably building regs you need to be more aware of going to this size
Hi, If you are 4mtr's away from your closest boundary, can you build your build higher than 2.5mtr
Cheers paul
Bought a dewalt spade bit costing £6 and a cheap unbranded £3 bit from screw fix , the dewalt bit was useless , the cheap and chearful bit drilled over 20 holes without a problem and each within 10 seconds
So theoretically i could build 29.99 m2 building (internal m2) with huge canopy , 4.6 x 6.2 plus 3m canopy on side? 1m from boundary less than 2.5m height and less than 50% of garden
@whatsMyNameAgainAgain actually it’s the internal usable floor space , just saying, had many council inspectors round, have you?
How can you get away with 28 square metres? Without planning permission? I thought it was 15 square metres maximum. Or is there something to do within one metre of the boundary?
This build is more than a mtr from both boundaries 👌
@@thegardenroomguru OK but it's combustible material it's wood right?
The whole combustible materiel thing is completely up for interpretation by whom ever reads it mate. Some say metal cladding fine or non flammable coating on wood, others say got to be block or brick, there’s no definitive answer, all councils say different things, because it’s not clear enough, we did one in Barnsley, neighbours weren’t happy, guy from council came out snd was only interested in the height, off he went happy it was under 2.5 🤷♂️
How does your crew keep up with U, 💯 Miles an hour 😅
The height of the structure is to be no more than 2.5m is that from ground level or from the flooring? I ask because if i raise it up to have decking out from it would i have to sacrifice some of the height as opposed to doing it at ground level.
From ground level mate
Unless your a metre away from the boundary then you can be 3m 😜
@@jamesfox7196 I thought it had to be 2m from the boundaries? I've 10m width but a really long garden. I'm hoping to go 5.5m wide by least 7m depth so can go over the 2.5m height and do a apex roof instead... Wish Liam and co get chance to do similar for another client and video that for us all 🤣
New lad on the team?
Is 28 sq. Metre the permitted development maximum for Building Control..?
30sqm internal floorspace.

How to build a garden room and send you're blood pressure through the roof at the same time😅😅
Hi keep it up you are doing a great job and having fun making some brilliant videos superstar Ali Walsall west midlands england junction 10 m6 Walsall churckery
Taking the guard off the grinder. Asking for trouble
This build would require building regulations approval
its more than a mtr away from the boundary, so no
You can go up to the boundary but limits to 2.5m in height
Wheres the health and safety here, workers using angle grinder without the safety guard, absolute cowboy. Slow down
Love it when people call me a cowboy 🤠
@@thegardenroomguru you wont be loving it when one of these boys looses a finger and you are being sued
@terregles09 after 8 years, not one injury, everyone has moved on and everyone has all there fingers. 🤫🫠
Ain’t you suppose to have a guard on your grinder and wear eye protection? Be careful posting that online, always someone out there to get you
Hi Liam fantastic build I’m looking at building one in my garden 5m x5m with a 2.5 canopy would two 5x2 bolted together be sufficient to span the 5m gap or would I need to use flitch beams or could I get away with 6x2 bolted together thanks
