30Mbps should be good enough for video calls, but of course depends on how you're connecting and building construction etc. I know I would prefer a wired connection. RE openreach, make sure they understand that it isn't a new site and there is presumably a pair on the pole that served the bungalow (unless someone else is now using them of course). Have you checked altnets? Giganet and CityFibre might be in your neck of the woods

Can you do warm roof but take back the house roof to give you the height? You need careful detail around the transition to ensure ventilation into the cold (I assume) house roof. An wider external pic might help others give more suggestions

Interesting, unusal for a switch to cause such a fault, but I hadn't realised it was an attic switch which I guess is more "exposed"

You need to keep splitting the circuit until you narrow down the cable with the fault. This will be a lot easier with a tester that can do insulation resistance testing. You can pick up used testers on ebay, but probably cheaper / easier to get a spark in

How is the pointing? The flashing doesn't look the tidiest. I had similar but was able to remove the stack, and the roofer said it was so bad he didn't need tools to remove the bricks 😬 Has a good roofer had a look at it?

Is the floor "bouncy" or is it just squeeking boards? If just the later, as @joe90 says, just get some scews driven in to pull everything tight

How many cores? How is it installed? This is a useful calculator: https://www.tlc-direct.co.uk/Technical/Charts/VoltageDrop.html

Not a plumber Is there air in the system? Does the pump have somewhere to pump from? e.g. are radiator valves / TRVs open?

I was going to say I'd want the control room bigger if it was for recording. My knowledge is more on a recording build, but essentially bass will be your biggest issue, so lots of mass and decouple everything where possible. You will also want to kill reflections etc especially if you're loud, so soft furnishings will help a lot with this, if you're not able to build anything in at construction. Also bass traps in unused corners (wall ceiling junction is a corner too 😉 )

As above, you need mass your best option is probably MLV PB sandwich Is the space primarily for rehearsals or recording?

Pay particular attention to detailing on doors / windows, these will be your biggest problem. Is that a french door to the left of control room? It will probably be more leaky than others. Consider making stud walls double & decoupled Check your room ratios aren't going to cause acoustic issues I suspect you'll want the room pretty "dead" at that sort of size, so incorporate absorbers / bass traps in the design early on A great resource: https://johnlsayersarchive.com/ Keep us updated on your progress

Looks like a warm roof from the exterior pic. Ventilation through the wall if possible to avoid penetrations to the roof

Something like this?

Presumably you want the reatining wall to be stabalised, so I would be helpful as far as possible without it negatively impacting you significantly. What were the nature of the works you undertook to dig out? Was anyone involved to assess the impact on the wall? It is good that you have photos of the wall before works were undertaken

Just on your diagram - I'd keep services in the space between the plasterboard and the insulation if at all possible, just make sure your cables are run in the correct zones. One tip, if you have at least one socket on each wall, you can run the cable horizontally around whole room, making it easier to add extra sockets in the future. 🍻

Either insulation fixings or plasterboard adhesive foam 🤷‍♂️ - make sure you tape over any fixings Work Go for as much as you can afford / space allows Good question - I'd want a mechanical fixing in there, maybe foil tape over? I'd do some research on best approach. The wall I have done this on has a stud wall in front of it, so no penetrations as fixed to ceiling and floor Work out the biggest depth you need, might be easier with fast fix boxes, but I'm never as happy with them as a proper backbox

Ventilation comment was for the room, not for the walls I was proposing a single continuous layer of PIR, then battens. So your build up from outside in would be: Existing block wall PIR, gaps and joins foamed and taped Battens Plasterboard

Continous layer of PIR with battens at 600mm in front of it giving you a service void? Need to consider ventilation, reveals need some thought too

Loftzone do a product that looks more stable than the cheap legs: https://www.loftzone.co.uk/shop-storefloor/storefloor/?attribute_kit-size=Starter+Kit+1.2m+x+2.4m Another member did an install here:

I'm just shy of 42 degrees, and if I wasn't constrained with it being a renovation and ceiling clearances etc I would have gone shallower. That said it doesn't feel wrong, just not as perfect as you would want in dream build

The outdoor units will have specs of how much space required around them. I don't think N, S, E, W will have a big impact so go with wherever it will be least annoying athestically and acousticly (e.g. don't put next to bedroom window), and factor in pipe runs. Are you having an unvented cylinder for hot water? I would go with a plant room (large cupboard) to house UVC, UFH manifold and controls

Login to your router, look for the list of connected devices and identify the NVR? Have rebooted both technomates? - I don't have them, but could be worth a shot? Verify you can reach the NVR on your local network, if you can, then look at the app/remote side of things

Is the connection to the NVR wired or wireless to the router? Can you login to the NVR? Do as @Pocster suggests to check it is on the router and to get the IP I'd be checking the following, depending if they are required by the app Port forwarding UPNP DDNS

Love a hairbrained scheme... There is an interesting series of videos for an overshot wheel here, but obviously you would need it to be undershot. The wheel did have to be rebuilt as the driveshaft snapped
