Hi Ryan, good question. I hit in a couple of nails on each side at the correct height so that it will keep the insulation from falling through. You could nail a batten along the underneath if you are using insulation the same thickness as your joists
interesting that you used quickset cement to build up the foundation blocks. As a rule this can be prone to fail over time and doesn't have great compression strength for the weight of a typical building. its not designed like a concrete mix and given its exposure near the ground can fail under frost and wet. did you get any structural advice? Just asking as I am a structural engineer.
Nice. I appreciate the simplicity of the build and your clear explanations. i hope to be doing something similar although a little smaller in the spring. (The shed is on it's last legs and just about to be emptied into the garage which will provide a new home for the lawnmower etc..
Just wandering where you bought your vapour barrier from? A lot of them now are so opaque it’s hard to see the joists through them for fixing…yours you can see through nicely
Really appreciate the videos. Just wondering what the sound travel is like into/out of the office part? If someone is on the phone in the office, is it easy to hear the conversation from outside?
Hi Sebastian, thanks for your comment. Glad you are enjoying the videos. The sound travel is pretty good, it’s much like the structure you would have in your own home if you have partition walls not made of brick. You might here that something is being said, if outside was completely quiet, but you cannot make out really what is being said. With the other build on my channel, I implemented greater sound protection and you cannot hear a sound when it comes to speaking or general TV/music.
I'm looking to build a garden room I've had a few builders saying I would need concrete base, but you seem to have not done that and done on stilts. Any recommendations please
There are pros and cons to the different options. If you need to be mindful of the maximum building height, then concrete base is a good option to keep it lower to the ground. You can use concrete piers or even ground screws which are becoming more popular.
When you inserted the jabfloor insulation whats holding it up? It appears to be just slotted invetween the noggins? Is there some bracket or boards under neath that ive missed?
You mention wanting to keep the height of the building down to a minimum, yet you have built onto blocks rather than a concrete base as you did in your previous build. Did you make that decision based on the size of the concrete pad you'd need and the cost of getting it poured?
Hi Paul - thanks for the comment. There were a few factors. One is that the ground level adjacent to the building was raised to start with, so even with blocks, I could start the floor at ground level. Secondly, it was yes due to the cost involved in digging out an existing concrete base and installing a new one, and also the time that it would take to do so. Inside the finished height is over 225cm from what I recall, so it feels nice and roomy, and could afford to loose some depth with the floor joists.
No it still falls into the threshold of permitted development as any structure will need some kind of foundation, whether it is block piers or a concrete base, so long as the other criteria of permitted development are met with the building.
If you refer to timber floor joist span tables, which you can easily find a copy of on Google, there are definitions of the clear span allowed to comply with building regs based on the strength and dimensions of timber used, the centre spacing of the joists and the expected dead load on the structure. Based on my build and calculations, 2x4 can support a unsupported span of 1.6m (distance between the blocks) which factored into my design in terms of positioning of the blocks and number required. If you were to use larger timbers, then you could increase the span and reduce the number of blocks required. But no reason why 2x4 are not strong enough if the right number of supporting pillars are used.
I really enjoy these type of projects. Thanks for sharing.
Thanks, glad you’re enjoying them! Will keep them coming.
Hi, Just wondering what hold the insulation in place on the floor? Am I missing something? Just about to start doing something very simular myself
Hi Ryan, good question. I hit in a couple of nails on each side at the correct height so that it will keep the insulation from falling through. You could nail a batten along the underneath if you are using insulation the same thickness as your joists
Any demonstration on how you kept the insulation from falling out?
Not sure if you can see it, but hit a nail in each side of the box section at the depth of the insulation, that will stop it from falling through.

Thanks for taking the time to comment. Glad you have found the videos useful and good luck with your build in the new year!
@@leejmurphy Thanks. I followed your previous series on the drum studio as well. Also very useful.

I’m fairly sure I got it from Wickes
Great thanks very much indeed. Wish me luck ! 😂
Very helpful, thanks but... please, no more annoying background music.

Sorry to ask a stupid question. Is there any to use to hold the insulation slab in place (just wonder if they fall through the subfloor. Thank You
Just fixed some nails at the same depth as the thickness of the slab to stop it falling through

I fixed nails around the joists and noggins which were the depth of the insulation in order to keep it up
Which program do you use for your drawings
It’s called SketchUp
Thanks

Do you need planning permission to build something like this? Ive heard having foundations puts it in a different category?
No it still falls into the threshold of permitted development as any structure will need some kind of foundation, whether it is block piers or a concrete base, so long as the other criteria of permitted development are met with the building.
Interesting I'm about to start one but the music is annoying me too much
4x2s are not strong enough
If you’re building within the ratings/standards of floor joist span tables, I don’t see why they wouldn’t be strong enough?
Please expand on this...
