Just to say that You need the regs .
For change of use.
This comes with a building inspector.
The building is inspected buy the council building inspector to insure the
Principle contractor has met the requirements or the regulations.
You don’t have to make sure it’s built to the regs . He does.
You don’t have to use council building inspector.
You can hire a professional company.

Converted mine including new roof, brickwork repairs, blocking up door, small toilet/shower room.
It was single skin brickwork so opted for external render and internal sand cement render with 54mm insulated plasterboard.
Did a lot of the work myself and cost about 10-11k all in.
Garage is 2.7m x 7m

I live in a conservation area and wanted a change in design, so a bit tricky. Just put some effort in for reasons for change, and they approved it, luckily.
Sadly, as I have found out, the inspections are not what you think they should be. If you notice something that's wrong and mention it to the inspector, he will make the contractor change it. However, if he can't see it because they have covered it up, he won't make them take it apart so he can check.
In addition, there is even indemnity insurance that can be bought to cover the lack of certificates. I've had to do that in the past when we got windows fitted as a private job and didn't end up with a FENSA certificate. It only really becomes a problem when you want to sell the property though.
We had a garage conversion done about 4 years ago. Bedroom and wetroom for my disabled son. We've had no end of problems with it, the worst being that the heating and hot and cold water pipes freeze whenever it gets below -2. This was because the builder decided he didn't want to build according to the plans as it was more expensive. We end up with a cold roof rather than a warm roof, which is why the pipes freeze as they are in the air gap above the insulation. He bodged the shower tray under the floor too so we will need to budget to fix the whole room at some point in the future. This was after he'd done a lot of other work around the house for us that we were really pleased with. Shame as I'll never use him again, nor recommend him to anyone now either.
Ours was about £25K if I remember rightly.
I'm currently saving to convert the 50m2 outbuilding at the bottom of the garden (single skin block built with a huge garage door sized opening at the minute) that was here when we bought the place. I intend to do as much of that myself to keep the costs down.

I've been surprised at so much, I had a pop up gazebo in the garden for a year or so which I bought to work under on my cars, while i had it I thought id store some things in it so setup on my patio, all winter you had condensation on inside of top, even if only 2 sides on it was same, I also have some of the Keter plastic sheds one is 6x4ft and same with that every winter water dripping from the roof of it so pretty useless for storing many things
It's absolute nightmare with cars outside, got covers over 2 but then steering wheel ends up covered in mold unless you keep taking them off which is a pain
My Arcade building is fully insulated but not heated, with Solar Dehumidifier it's kept damp free unless we get a real long spell with no sun but cost is zero unless you want to use in winter, with intergral garage it's much easier as you could add radiator from house.
If you using for Arcade machines how would you get them in out, depending on size, I would have thought keeping garage door ideal. my side extension is only 6 odd foot wide but I had double doors on extension at end of the drive before having it extended to front of house and wanted it to look more like a garage, (could be if you owned motorbikes) so I fitted the double doors I had already and then had roller shutter fitted in front, so have double security and looks like garage. wouldn't want it with just roller shutter, too noisy being other side of lounge.

I would agree that temperature control and insulation is way more important than people think in the beginning. First because you simply won't want to spend long in a cold room or a hot room. And secondly for the lifespan of the equipment.
I have one of those garden room things you see.. made from wood. It's really decent. Instead of a air con unit (which is the best option) I went for a Dyson Fan/heater purifier. They are damn expensive but still a grand cheaper than a air con as well as being portable.. it's all app controlled so I have it on half an hour before I use the room. Keeps the room a constant temperature when I need it to.
Air purification and especially a dehumidifier are your friend with arcade equipment as well.
wouldn't ass about with bricking the door..just make a stud partition on the inside..looks how you want inside and like a normal garage outside .
Good luck

My house is listed.I live in a listed cottage. I had to get planning permission to get a new front door.
I actually like it - sometimes bits of history need protecting from idiot home owners (not suggesting that in your case, but there'd be loads who'd fit an undersized bright white PVC door to a 1700's thatched cottage if they could).
I had to get planning permission to put an internal doorway back to where it was in 1855, but it wasn't a huge amount of paperwork fortunately.
I want something permanent like this in my garden, Dan. No 10 year warranty plastic sheds for me!I do this shiz for a living I will help you 👍😁❤️

65 bricks to a Sqm Try to get a brick less than £1 each
If your only doing the garage door area
Look for reclaimed bricks …
Also you can get reclaimed windows as you can build your wall around the window size …..
So source a good surplus te requirement window ( could be a brand new window but the owners miss measured ) .
Then source reclaimed bricks .
Same with the insulation .
You can build the walls ( internal + external up on concrete lintels ..
Therefore exculpating the need to dig a complete foundation from side to side .
We call this a concrete pad and a pier with lintels .
Saves time / money / sweat /tears / usually some blood 🩸/ and the removal of spoil! Which also requires normally to go into a skip more money!
If you think you can find your damp course to the house …. You match it !
Set up a string line from your house damp course across front of your garage door area to build wall..
Then work all you measuremts fom that line.
Foundation pad of concret normally 1m dig down from the damp course line .. with 600 mm of concrete for the pad .. pad norammaly in this case
600mm wide ( this is the cavity wall direction ., and 600 long .+ 600 deep .
WATCH OUT ⚠️. GAS /‼️ELECTRICITY⚠️. Not only do I normally find gas & electricity in the garage door area just under the ground .. it often has your neighbours too ! ….. so. Super extra precaution needs to be taken here !
This requires the CAT scan tool from the hire shop . You need to use this tool to detect for services of gas and electricity in the ground where you are doing any digging .. and then because gas is in a plastic pipe you cannot assume your ok anywhere ..!‼️⚠️…
So this means you need to dig it by hand only and slowly .. even if you know where your gas and electricity comes into your home . You don’t know if they sneaked the house next doors in to you same Chanel in the ground … And yes they always do share the trenches they dig ..
If hard solid concret to get through first .. you need to be so careful of using a kango concrete breaking drill
Your services could be just underneath !
One trench can have all the services in it ! For two house .. maybe even three !
If your ok with everything I have just informed you of ,
And your prepared to roll up your sleeves and with a friend or two !
Sometimes having a friend help you is also because if you get into difficultly & require help
They can ring 999.
Like being electrocuted .
I will guide you further on your adventure if you want to proceed.
Yeah, I get it, but people like that would just stick in a crappy door without asking for permission. It's all just an extra ball ache with a listed property, and an added expense. I think my application for the door was about 380 quid, and I've loads of other work that needs doing.
Struggling to get motivated to tackle it all, and finding good builders that will do everything properly is difficult. I've got the money to have everything done, just seems like so much to do, I can't be arsed to tackle it all. I did have various structural repair work done last year, though.
This is the state of my old games room, and god knows when I'll be able to use it again. Maybe I should just move. Lol
