It will need planning permission, but the fact you already have a tall brick wall on the boundary should make that much easier.

That is strange. What little I can see of the exterior wood and paint looks okay. Almost as if water is getting in at the top, perhaps from the cavity that does not have closers?

I had multiple hdmi cables to our main tv points. They all lead back to the AV cupboard under the stairs where all the set top boxes reside so there is no (or little) "clutter" under the televisions. Wall hanging a modern flat screen tv raises the question where do you put any set top boxes, that previously would have gone on a shelf in the "tv unit" It also means the same set top box can serve both tv's downstairs so a recorded program can be watched in either room, and only one firestick for all the on line stuff. hdmi splitters and 10 metre long hdmi cables. Install more cables than you need in case one fails or you want to add something new.

Gas safe certificate from gas safe installer, just like any other gas installation. Note not all gas safe engineers are register for LPG.

Scrap the stupid CIL system. That has to be a major deterrent to builders and of course pushes up house prices as it effectively makes building land more expensive. The sustainability nonsense is just plain stupid. Up here the planning guidelines are more sensible, they want development in existing settlements not isolated individual houses. That is the guideline that allowed our present and previous self build. But we are 3 miles from the town and public transport. Yes you could cycle that, but it is uphill all the way back. Few do. But such development is still allowed. If the planners won't allow provision for an EV car (charge point and possibly PV) as "sustainable" then that is plain stupid.

My BIL lives in a house where this was done successfully a long time ago by a previous owner. His corner plot garden is now enclosed by a nice mature Beech hedge right on the boundary substantially increasing the garden compared to the small bit originally enclosed by a fence. but he bought it like that so he did not take the risk of being told to take it down, or having to wait for it to grow. And the garden was all flat to start with.

I would first pressure test the drains, to ensure the "damp" and smell is not being caused by a leak in the drains somewhere.

Have a look around the surrounding houses. Has anyone else done this? If no, there is likely to be a planning condition or covenant preventing it. You might get away with it but being on a corner visibility around the corner for traffic may be a concern. In any event I would not try and enclose anything in front of the front wall of the house. A hedge might enclose it, and if nobody complains once the hedge has grown to maturity to screen the garden you could let the wall fall down. But a hedge will do nothing to raise the ground level, for that you need a retaining wall, completely different thing, so you might end up with a bigger, but sloping garden. If you have not yet bought the house, £3 gets you a copy of the house deeds from the land registry. Find out if there are covenants or restrictions on the use of that bit of land, e.g it might be designated amenity land. Or look for a more suitable house to buy that gives the garden you want?

Is it as bad as you think? In your picture the bottom string looks at too high an angle (compared to the newel post it is trying to engage with) if it was at the correct angle it would be lower and the "adjustment" needed would be less. Still the manufacturers problem, unless they start throwing the "you checked the drawings" card at you (I know someone that got stung by that) Ours got the newel posts wrong as well, but thankfully that was all, and it then took them 2 more tries to get the newel posts right.

My BIL hung on to the end in charge of decommisioning one of the major instalations. I baled out nearly 30 years ago, glad I did doing so preserved my pension.

I had involvement with JET nearly 30 years ago now, and it was always the standing joke that Fusion power will be 25 years away, always. It was certainly an impressive bit of kit and fun to have worked on, but whether it represents value for money is doubtful. But if you don't try an idea you will never know. I still know a couple of people who worked on JET right to it's end, and in the latter years their job became maintaining a >30 year old control and instrumentation system built of now obsolete technology, so they became experts in repairing and maintaining the old kit, and scouring the world market to buy up any spares that became available.

Until recently, house buyers largely ignored EPC's and bought a house because it looked nice. Then complained it was draughty, cold and cost a fortune to heat. Landlords are the low hanging fruit, easy to say you can't let a property unless it is an EPC C, a lot harder to say you can't buy or sell one below EPC C. In recent years a lot of poor EPC properties will have been sold by landlords as they don't want or can't afford to upgrade them. What is really needed is a mechanism to make poor EPC houses genuinely be worth less than good ones. Quite how you achieve that without being "unfair" is difficult.

It saddens me how little regard people have for tradesmen. You think they are all a lazy overcharging bunch of wasters? I had always preferred to charge by the hour rather than the day, that way I do 7 hours, you pay for 7 hours. I also preferred to give estimates not quotes so again you only pay for what the job takes. Every time I have mentioned this I get shot down and told people prefer a fixed price. I always got the vast majority of my work through word of mouth and recommendations. That is the lifeblood of most sole traders. If you really have such a low opinion of them, don't recommendation, and they will soon be out of business.

Can nobody do maths here? 1,500,000 houses over 5 years = 300,000 per year = THE EXISTING TARGET (that has not been met for many yers)

Hinge the door the other side otherwise the open door blocks the bedroom doorway.

I count 154 "points" I used to estimate on the basis of 1 hour per point. So 154 hours. I am out of touch with labour rates "down south" but a few years ago I would be quoting just under £5K for the labour for that. I would guarantee southern rates will be a lot higher than that, £7K for labour would not surprise me in the least. Materials will add up, they could easily be another £7K depending what you want.

We have 8 houses sharing a 100KVA transformer which is where they derived the 12KVA that they offered me with no upgrade charges. They don't seem to apply diversity. What surprised me was when installed it was the same size cable as they would use for a 21KVA supply and they fitted a 100A fuse. You could ask what fuse they would fit in the supply head if you accepted a "3KVA" supply? I think the smallest would be 40A which would amount to 9KVA But with that many houses on one 100KVA transformer it does sound like it is time they upgraded it, and it still looks like they are trying to get you to foot part of the bill for that.

That would work if done as a full wet room. You would want to avoid too much water splashing on your door and into the WC area. For that in our wet room (shower in corner) I use two of the cheap over bath shower screens. Hung on the wall so the bottom is 100mm above the floor and the top is about eye level for me. The don't stop all the water splashing but most of it, a little will splash over the top and there will be some bounce at the bottom, but generally it keeps the non shower parts of the wet room dry. when not in use they fold almost flat against the wall.

Up here, if you go above 5 properties on a private road, that triggers a requirement for you to upgrade the road to highways standards and the council to adopt it. Check if that applies where you are. And one of the plots we considered buying had a clause in the planning, no building on the first 3 metres from the road, to allow for a compulsory purchase to widen the single track road.

Don't laugh but when I had to do a similar thing, I cut out cardboard shapes to scale of bath, shower wc, basin etc and their respective activity spaces and played a game of tetris with them to find a layout that would fit.

Your present system probably has a cold water tank in the loft, often a very flimsy plastic thing, did you worry about that?

My take was install all the cables you think you will need, but only connect the ones you actually have a use for. Like you I installed 3 to each tv point but I can never see all 3 being used. Partly my reason for installing several was in the event of some cable type superseding hdmi, I can probably use 2 network cables and a clever adapter to replicate the next standard in AV cabling. I think what I am saying is you won't need a 48 port switch.

If those sustainability guidelines were applied here, none of the plots in our road would have got planning permission.

Post the exact model number, I would be surprised if it can't do cooling. It might need an internal switch changing to enable that function. Cooling to radiators will work, just keep an eye on cooling water temperature so you don't get condensation on the radiators. ASHP cooling on a sunny day is free if you have solar PV as well.

The clue is in the name "evaporative". It "cools" by evaporating water. So it puts water vapour into the air. What else do you think will happen to the humidity in the room? Many will say this sort of "cooler" is snake oil. The only way to cool the room, is to remove heat from it. Something your ASHP is likely capable of doing?
