All I can think is asking them how much they would want to give up the ROW permanently? If they are willing then best do this formally so it gets removed from the deeds once and for all. A surveyor might be able to estimate what the right value is eg what it increases your house by and how much it reduces theirs by.

How big is the duct? If big enough could you push another duct through it for the water or electric just to give a bit more protection/separation.

What car is your wife driving? Even a three year old Fiesta has hill start assist these days. Is it turned off?

You may also be hit with a planning condition requiring an Archealogical survey. These can be rather open ended.

Just looked at Part M again. I think you need to get a copy of the planning grant for your house as many sections of Part M are now only mandatory if there is a planning condition requiring compliance. Depending on what the planning conditions say you might need "accessible thresholds" on "other external doors" in addition to the front door/principal entrance. See the intro to section 3 then section 3.23 which refers to back to parts of 3.22. But even if this must be a wheelchair accessible entrance it looks like the sill design wasn't intended for that. This looks like a normal upvc patio door that has been installed lower to try and make it comply with something it wasn't designed for. It looks like a bodge, perhaps because their door/window supplier doesn't make one with a sill that is intended to be wheelchair accessible? I suspect the strip of concrete/screed along by the door might even be a crude attempt to make a ramp, perhaps to make it comply with the 15mm high threshold rule)?

Our system is pipe in foiled insulation with spreader plates. We have 80mm of PIR insulation under the UFH system so I guess equivalent to 85mm? That's over a beam and block floor. Pipe spacing around 150mm. We turned the flow temperature up because the first winter was very cold and the heating couldn't quite keep those rooms to the set temperature. Not helped by no curtains in those rooms. Our engineered wood floor has coped with the highish temperatures ok.

OK the drawing from that link is similar to what we did for our front door. However it won't solve your other problem which is an inability to open the door if you fit carpet or wood flooring. To solve that the door and sill need to be raised, probably at least 20mm. But if you raise the sill you have I don't think it will meet wheel chair access regulations as it will probably be too tall. Its hard to tell from the photos but looks like wrong design. Regarding the water ingress... The weather seals on many doors will leak to some extent but they are normally designed so that any water that does get past the seals drains through passageways in the frame to the outside. This is sometimes called secret drainage. If they are installed too low or incorrectly this drainage route can be blocked and the only place for the water to go is inside the house. There is also the possibility of it collecting in the frame and freezing in winter. I would try and get information from the door manufacture. Check if it's intended for wheelchair use. Check their installation instructions have been or will be followed regarding drainage of the frame itself. This photo shows secret drainage holes on a window. Don't let the builder just drill holes, they will be designed in by the manufacturer.. And this shows the complicated path through the door and frame that water can take on some doors. Try and get the equivalent drawing for your doors from the manufacturer. Regarding the need to be wheelchair friendly.. I know the regulations have changed since we built our house so it is possible they have to be. Perhaps a planning condition was imposed requiring greater wheel chair access.

What solvents have you tried? I've got a growing collection that work on some things but not others. Acetone, IPA, Petrol, White Spirt, Methylated spirit, Cellulose thinners etc, Test on somewhere out of sight first.

PS: If this door does need to be wheelchair friendly for some reason.... I believe they have used the wrong type of door and sill. It looks like they have just fitted a standard non-wheelchair type too low in the hope that will do. A clue is the thin upstand nearest to you in this photo. I don't think its strong enough for a wheel chair to drive over regularly..

Total BS. 1) The Building Regulations (Part M) normally only require the front door to be "level access" and even then you are allowed a 12mm high step/weather bar above the finished floor level (eg above any wood flooring or carpet). 2) There is no excuse for a loose frame. 3) The water is coming in because its not fitted correctly. Worse they propose sealing it with tape on the inside ! Totally wrong. The water seal should be on the outside but that might mean taking the door out and fitting it correctly. As others have said the door needs to come out and be correctly fitted. The door might need to be remade.... It's quite possible they measured or built the opening incorrectly so when it came to fitting the door frame it was too tall. It's too difficult to raise the lintel above the door so they probably removed or cut bricks at the bottom and installed the door lower than it should be. The correct thing to do was get the door remade.

We have 21mm Engineered Oak fixed to battens with UFH and spreader plates, no chipboard. We have had to turn flow rates up to 50C. House built to the regs in 2007. If we had ASHP (eg lower flow temps) I wouldn't want 20+18 = 38mm of wood over the pipes.

Sorry I can't remember.

I filled about 6" with expanding foam, but my duct was for power and the end was buried under a patio.

Ignoring the class aa for the moment.. Adding a side window is only permitted development if you fit obscured glass. Otherwise it needs planning permission.

Restrictors.. https://www.screwfix.com/p/smith-locke-window-restrictor-white-200mm/218HR?kpid=218HR&ds_kid=92700058176431263&ds_rl=1244072&gclid=CjwKCAjw1ICZBhAzEiwAFfvFhFN_OVI9RzxY2CyRkjx1HrucCxIL8dzw2IjpXDPQSPMQABzDtOG0GxoC_XsQAvD_BwE&gclsrc=aw.ds

We had same problem. BCO just asked for a wire to prevent the window being opened more than a few inches like you get in hotels. Cant think of their proper name.

We've had an IBC on an allotment for at least 6 years. The sides were wrapped with reed fencing/matting but top was left exposed. Not noticed any deterioration.

Don't be tempted to get the whole roof sprayed with foam. Some adverts claim its a cure for slipped tiles but it just makes things harder to fix longer term.

More photos from further away would be good.

If Building Control are involved they will have a view on the minimum thickness.

Hadn't thought of that but it's pretty small bore. About 8mm I think.

I wouldn't pay too much/anything for advice initially. I would write to the planners and say you would like to understand which part of the General Permitted Development Order they believe has been breached as the guidance says "as originally built" and defines that in your favour. If they don't come back with a justification/case law I would wait to see if they send a formal enforcement notice. They may never send one if they cant find case law to support it. If they do, then at that point I'd pay for advice, probably an initial opinion from a Planning Consultant.

+1 some of the tracks on the backside of the PCB might be burned. Not always fatal. The relay with the black hole on it appears available... On ebay from China.. https://www.ebay.co.uk/itm/383276724859 or Poland https://archiwum.allegro.pl/oferta/nf7-100-e24-nf7100e24-pk-zwierny-24v-16a-250vac-i10750260248.html Might be other sources in the UK.

Google says it is possible to buy a retrospective structural warranty or a PCC, but see if you need one first as they are probably expensive. Having the Architects cert might reduce the bill? Shop around. These mention retrospective policies but I've never used or even heard of some of them. Check they are accepted by the Council of Mortgage Lenders before paying up. They may not all cover self builds. https://ahci.co.uk/retrospective-insurance/ https://buildwarranty.co.uk/professional-consultants-certificates https://buildsafe.co.uk/retrospective-building-warranty/ https://compariqo.com/retrospective-structural-warranty-what-it-is/ https://granitebw.co.uk/knowledge/replacement-building-warranty-cover/ Several others found.

Our condensate drain is a small bore plastic tube with no trap at all. It discharges onto the ground near back door. Have never actually seen anything come out of it. Never been a problem. Your mileage may differ 🙂
