Temp

I think 7 courses of the 54mm brick is about the same as 2 courses of blocks, both with 10mm mortar.

Personally I would get a solicitor involved or at least find out what they would charge. I've only briefly looked at the application form guidance but I think some sections like number 10 need the right wording because it goes on the register. My understanding is a caution just means you get notified if someone applies to register the land and its at that point you have to prove your right to whats put in section 10. So I think its important that the right things are claimed? They may also be able to advise if its possible to word the application so that future owners of your property are notified so the caution doesn't have to be changed when/if you sell up.

There is bound to be a youtube vid showing how to do it. Its not a very difficult job. Perhaps 15mins or less. Needs a few spanners and a feeler gauge.

To claim full ownership would be very difficult. Typically you have to fence off the land "to the exclusion of all others" for 10/12 years. I believe allowing the owners of the other properties to continue to cross it would preclude this. I believe you are entitled to an easement "by perscription" (use over time). Have a look in here if not already seen. You will most likely need a solicitor withe experience in this area rather than a general conveyancing solicitor.. https://www.gov.uk/government/publications/easements-claimed-by-prescription/practice-guide-52-easements-claimed-by-prescription#:~:text=1.-,How prescriptive easements may be acquired,by lost modern grant

Can't comment on the choice of render but i do know that a good render job needs attention to details with things like drip beads in the right places. Some render is/isn't approved for use below the dpc etc. Perhaps worth googling for guides.

Tip for the B&S engine.. Some have an automatic decompressor cam that is intended to make starting easier. However the cam hardly lifts the exhaust valve at all so its operation depends on the valve rocker clearance. So if the starter on your B&S engine struggles or even fails to turn over the engine it might not be the starter or battery. Check the valve clearance is spot on.

Some time ago there was someone on ebay making replacement decks (just the deck). They were a bit agricultural looking but probably used thicker metal. They were way cheaper than buying a whole deck assembly like some makes insist you do.

I guess you can't run the beams the other way?

Hope this is allowed. I have no connection with the company except as a happy customer. "All Finishes"have been recommended here before as they usually have good prices on paints. Today they have 10% off if you enter code VALENTINES10 https://allfinishes.co.uk

Fix curtain pole to the ceiling.

If its a partial vacuum your own AAV should be able to deal with it by opening to let air into the stack. That is assuming it in the right place on the pipework and not sealed into air tight boxing.

That second rule is a life saver for people that only hear about the scheme after they move in.

I wouldn't be surprised if there was no insulation or badly fitted insulation in the vertical stud walls of the room in the roof. Thus the ventilated eaves are just plasterboard away from the room. I doubt there is any access to inspect this area. Might be worth drilling a few holes and using a USB endoscope camera?

Emergency cut off switches are meant to be brightly coloured so you can find them quickly in an emergency.

Have you moved in or is it still empty? Your builder must start work before you move in to get the vat reduction

I'd be using it to measure the air temperature near where the room thermostats are mounted to confirm they are reading correctly.

I would also put a french drains under the extension and on the side with ground sloping towards it.

Did you manage to get a thermometer to check your room stats are reading correctly? Enough of us have had issues with stats to make them essential. Personally I like something like this because the thermocouple isn't encapsulated so it responds reasonably quickly to temperature changes. https://www.ebay.co.uk/itm/TM-902C-Digital-K-Type-Thermometer-Sensor-Thermocouple-Probe-Detector/353269567728?hash=item524081d0f0:g:RCQAAOSwf1RefYrd

That blue painters masking tape isn't very strong :-)

Duct normally comes with a thin string that is used to pull a thicker draw rope through. Toolstation/screwfix sell suitable polypropylene rope.

Here is one that uses a 3g SIM. Will still need power but can work from 12v battery. https://www.ultrasecuredirect.com/wireless-intercoms/gsm-intercom/kp6-3g-gsm-intercom-006-1990-p1872.html?gclid=Cj0KCQiAyJOBBhDCARIsAJG2h5eNr66OOB_PjPjr06NSG0aHq52ChIlPgK46SRjJeTI91rWzK59-T1MaAk3TEALw_wcB

Google "4g doorbell" without quotes. There are some but how good they are i don't know. https://www.aliexpress.com/item/4000094976724.html?spm=a2g0o.search0302.0.0.17e7376ehiLWdW&algo_pvid=a5146855-dbee-4444-a051-51732769d23a&algo_expid=a5146855-dbee-4444-a051-51732769d23a-2&btsid=0b0a187916130640592934493eb938&ws_ab_test=searchweb0_0,searchweb201602_,searchweb201603_ Edit: That one mentioned 4g but it appears to be wifi or wire only!

It sounds like the same applies to exports. Numerous companies are looking at moving jobs abroad so they can do B2B exports to themselves and then B2C within the EU. Even the government is advising companies to do this... https://www.thelondoneconomic.com/news/relocate-to-eu-to-dodge-brexit-bureaucracy-officials-tell-firms/24/01/

Lamp post?

It can go either way... it a fine line between a "contrasting high quality contemporary design" and something "totally out of keeping with other houses in the area".
