Ali Dymock Im in the process of building my workshop. Very similar construction 3.6m x 7.2m, suspended floor, flat roof. I’m a Civil Engineer so was able to be more economical on timber however you saved me a lot of research/reading (eg. warm vs cold roof, Lux). Your project is looking fantastic. Well done.
@andrewmason40044 жыл бұрын
Inimitable Knight can you give any examples about how to be more economical? For those of us still hoping to follow this path? I appreciate I'd need to do own research and at my own risk, but a clue about where to look would help. I had already thought another row of piers would reduce floor joist spans, so could maybe allow smaller (cheaper) timber there?

I built an 8m x 4m garden room about 10 years ago. My wife uses it all year round as a Pilates studio. I added electric under floor heating (for comfort as Pilates all on the floor)and my main heating method is an air source heat pump inverter that both heats and cools. This is one of the most energy efficient ways of heating as my system gives 3.8kw of heat for every kw of electricity used. In winter the room is really warm in about 15 minutes. Floor, walls and roof all insulated with 100mm Kingspan. The heat pump was theorised by Lord Kelvin (Kelvin temperature scale) in the mid 1800s. The heat pump is also used in fridges and freezers. The original name for a fridge was a Kelvinator. My building cost me about £10k in total and I recently configured the same spec on one of the big name garden room suppliers and their price was £46k including vat. It took me just under 2 years to construct the building. That was a long time, but I worked abroad a lot and the first year I was abroad 146 days and the second year 142 days so in reality it was about 6 months of weekend and evening work. I did the entire job single handedly, apart from mains and second fix electrics, and the A/C installation. Also got a professional to do the plastering and to lay the vinyl flooring. Some jobs I don’t think are worth attempting yourself. During the first lock down last year I also built a 6m x 3.66m workshop. It’s uninsulated and bleeding cold in the winter, but now I finally have space for all my tools and garden stuff as I built in 60m of 600mm deep shelves.

I recently decided to build a garden house and watched all parts of this video guide (good job!). And I watched dozens of other DIY for beginners. I started to think or highly doubt if all those who uploaded videos claiming the project was the first ever they did, is very hard to digest. The reason I am saying, the technical language, where and how to drill a hole, or how to install the gutter or fixing a window, or how to calculate the space or electric wiring. As I am a beginner/first-time building something, I got no idea or technical knowledge whatsoever, I am not sure if these folks who upload videos claiming it's their first project is true or not. Or how much time they spend to understand all this before starting the project. I spoke to several folks within the family and friends who want to start a project, but not even one person got the knowledge or even the names of material and parts like you can hear in this video or many other videos. If these folks learned it before (some handyman courses) and this was the first project, then yes, it will be a different story, understandable.
@SparkyNinja4 жыл бұрын
Your maximum demand calculation's are well explained. The application of diversity, as you mention, ,is really just an assumption of how the installation will be utilised. As an end user you may have been able to engineer the demand a little lower as you would have a much firmer understanding on how the installation will be used. We often use these formulas as a method of over compensating - we get away with it most of the time, but sometimes even that is not enough.

They are 8mm thick very heavy....mmmm considerably cheeper than magply which was coming in at £25 a sheet...ouch! Seems were jointed using a silicone adhesive also water proof and the joint overlapped with some flat pvc trim also cheep as chips...cutting drilling and screwing to timber frame was no bother and similar to plasterboard in this respect. The boards came primed in grey which meant it was easy to paint. I used johnstons paint for it, they could mix up just about any colour, its expensive at £70 for 5 ltr, i was lucky as they had them on sale with i think 60% / 65% off so i got 2 tins! Excellent product great as no need to prime the bare wood cladding used for the front. I didnt run water gas or waste as you did though so no need for planning permission.

*PLEASE READ:* Get your calculators out for this one! Sorry it's taken so long, the good news is that next week's video is ready to go too! Before uploading this video I sent it to a couple of electricians who pointed out that usually you would use 230V rather than 240V. So for example my 9.5kW shower calculation should be: 9500W / 230V = 41.3A I’ve done all my calculations again and put the end number of 84.7A (rather than the 82A in the video) into the Doncaster Cables calc and the result was still a 16mm2 cable over my 25m run so there's no actual difference. They also told me that there are loads of houses on 10mm2 cables so 16mm2 for a garden room is more than sufficient. Changing the video would have been too time consuming but just use 230V rather than 240V :) HOWEVER, just as I explain in the video about how there is voltage drop along the armoured cable, the same principle occurs for houses depending on the distance from the sub station and your house's voltage may vary anywhere from 220V-250V. Mine is 240V (as tested by Andrew, my sparky) so the calculations are right for mine but generally you would use 230V as a happy medium. Further info on size of twin+earth cables in circuits: Lights - 1mm Alarm - 1mm Sockets - 2.5mm Radiators - 2.5mm Sink tap water heater - 6mm Electric shower - 10mm *I'll admit I was nervous to post this video as I suspected I might get some flack in the comments from those in the know. These calculations should be taken to provide some underlying understanding and what to expect but I'd highly recommend getting in a qualified electrician to do all the calcs and work* 🤓
@tresslerj19854 жыл бұрын
I'm an Electrician and we'll done. 32A ring final is abit old hack. 20A radial for general power would have done and 20A radial for the heaters would have sufficed. Edit. Ring finals were used to save on copper. You would sling a ring upstairs and spur one cable through the floor and down the wall for down stairs sockets. Rings are generally used for kitchens or high earth leakage (computers) now.

Hi Ali, These really are fantastic build videos and it's very clear you have put the time in to your research and planning. I've been scouring the internet for the last 3 weeks to find something as extensive as this series. The only thing that I have read a lot into that I don't think had been mentioned was the matter of ventilation. I pretty much have the same foundation, structure, and insulation (warm roof) in mind, but was going to leave the void in the roof joists completely open and install soffit with holes and mesh backing to allow a flow of air from the back to the front of the building. I saw you filled all of the voids with PIR, so did you figure that ventilation was not an issue with the warm roof, or did you install another means of ventilation. I'm not asking because I think it should, but purely because I don't know!! You read so many conflicting points of view and your head gets scrambled. Great videos once again
@AliDymock4 жыл бұрын
Thanks, really glad you like them. So I wouldn't do that personally as that will under all the good work you've done insulating elsewhere as essentially all you'll have between the room and the outside will be a bit of platerboard and soffit - I'd also worry about insects getting in even with meshed vents-not such a big issue in the soffits but you don't want them in your above the plasterboard. A warm roof doesn't need to be ventilated but having SOME ventilation in the room is important so mine comes through the trickle vents in the windows and doors - hope that helps!

Worth saying that if this is going to be a continuous living space, you are much better off just adding gas and a boiler as this workout much much cheaper and make life easier as it will provide cheaper more efficient heating plus hot water for bathroom/kitchen taps and shower thus make for a simpler installation. Also, being that this is being spured from another single phase supply that will top out at 100A fuse and has its own appliances etc. This is not a very clever idea (at least arrange a separate Meter/supply). This could be mitigated by installing either three phase at the main supply or solar panels and a powerwall or the likes to the garden living space but that is allot of cost indeed.

Hi. With the lighting. Have you found that you have enough light. I just watched another video by Gosforth handyman and he just installed lights that were 4000 lumen each and he has 8 of them In a pretty small shop. Just wondering whether you think your lights are enough for a workshop?
@AliDymock4 жыл бұрын
It really depends on what you want. For a workshop I'd recommend going brighter, maybe 500lux but as mine will now be for general recreation 250lux is fine. The beauty of LEDs is that you can always up the lumens without using too much power. A white bulb will produce more light than warm bulb and white painted walls and ceilings will also help reflect light around your workshop but if it's all wood and OSB then less so. Andy's choice looks good for its purpose.

Very nice sneak peek at your decking. Can I ask how you did the decking base, same as your build base, concrete blocks?
@AliDymock3 жыл бұрын
This time I went for posts in the ground, about 60cm deep, postcreted in (I've done a whole fencing series showing the process). The joists are then attached to the building with joist hangers. The reason I didn't go for blocks is that they are pretty wide so catch the rain which will then sit on the block rotting the wood. Not a problem under a building when they stay dry :)

Hi, I have really enjoyed watching through your project. As an electrician this was a particularly intriguing section. Where did you get the height of the consumer unit from? 18th Edition regs stipulate the switch height (of the breakers) to be between 1350-1450mm in a new build. The only time I would position a CU at 450mm is if it was to replace an existing installation.
@AliDymock4 жыл бұрын
This was by far the toughest Part for me to make as I knew sweet FA when I started - i still don't know much as it doesn't come naturally to me. That height came from my electrician so I presumed it was correct! Good to know though, I may have to correct that in a future video. Does a garden room count as a 'new build' in regards to b regs? Maybe that's why... Other questions: - If a new house only has a low under stairs cupboard, does it mean you need to site the CU elsewhere? - My armoured cable when it comes through my floor comes out of the wall and into the consumer unit - is that normal and could it not have been put in the walls or is the current carrying capacity impeded like the other cables if it were to do so?
@azznoble4 жыл бұрын
Ali Dymock the armoured cable probably comes out of the wall before entering the CU in order to correctly terminate it. Your electrician needed to put a gland on the end which wouldn’t be done from the rear. Another way would be to gland into an adaptable box then joint it to PVC twin and earth in order to bring into the rear of the CU but that needs to be accessible, hence why it’s been done the way it has been. In the past I have worked alongside joiners who have boxed in the CU (allowing access) so the SWA isn’t an eyesore. I would deem your garden room as a new build as there wasn’t previously a CU, it’s a new installation as opposed to replacing/upgrading an existing one. For your other point, new builds are generally designed to allow for the services to meet current regulations (part P for electrical), all new builds I have worked in recently have had CU mounted at 1300-1400mm from ground level.

Ali, I'm building a simple room, nothing elaborate. Going to use it as a gym, Concrete floor and timber frame etc. Can I just ask, at what stage in the build would be most economical for me to get the electrics in? I just want a couple on sockets and lights. Is it when the frame and joists are up? Im planning to run the SWA through the garden myself and just get someone in to put it together. Also can you just confirm 400mm spacing for wall and roof would be suitable for both the outside 8x4 ply and better for the inside plasterboard? Thanks mate
@AliDymock4 жыл бұрын
Electrics -probably after battens to outside but while the internal wall are empty of insulation would be my recommendation. As for 400m centres - they won't fit 8 x 4' ply, no. So either cut the ply or go for metric sized OSB.

@tobysherring13693 жыл бұрын
@@AliDymock as you have such a large supply calculation and cable, the internal domestic consumer unit, whose internal rating is usually 100A, can't take the expected load of your additional building, especially with the shower, water heater and electric heaters. The incoming supply therefore gets split after the meter. A more general point is you have used the circuit protective device (breaker/CPD) rating for each circuit, rather than the expected demand, to calculate your load. Even with the diversity factor (ie you wouldn't use everything all the time) the figures are very high. The 6A breaker protects the 1mm2 cable (which could catch fire if loaded above 6A for a length of time, eg a short circuit or faulty lamp) but the load isn't 6A. The alarm draws next to nothing (1A or so) and could have been connected to the 32A power circuit with a FCU and 3A fuse. It's not a 6A load for your calcs. The 32A socket circuit is unlikely to draw anywhere near 32A especially as heating is on another breaker. What gets plugged in? You don't add up the breaker rating, but the expected load, then do the diversity calcs. Your 10mm2 supply seems much more realistic than the proposed 16. Has anything ever tripped? The main thing is that the CPD back at the house is the right rating for the size and length of cable run installed. I rate your building skills very highly and love the series. Electrics are the only bit I actually get...

So far I have enjoyed your videos, as a lighting and electrical designer, your lighting calculations are good and well explained, but your electrical calculations are terrible and what makes it worse you quoted a 10 year old version of the BS7671 on site guide. Calculating cable size is far more in depth and should only be carried out by a qualified electrician or electrical designer.
