Where in Devon are you? I am in Devon and just done a build with ufh, ASHP, and cylinder and can provide some input. I looked at mvhr but decided against it. Maybe post some drawings up and we can all look at the best way to fit it in. Also I have some ufh pipe and a manifold cabinet I am looking to get rid of if you need some

I very strongly doubt you will get permission for a house in that area due to the building line of houses to the rear. You may get permission for an extension, not sure if it would be covered under permitted development.

incorrect terminology used by me 😉

The courts https://www.mirror.co.uk/news/uk-news/family-lose-legal-battle-millionaire-31434575 https://www.bdbpitmans.com/insights/noise-nuisance-and-unlawful-alterations/ And the one i referred to for the daily payment, where the person below sued the flat above and won over £100k, rising £40 a day until the work was done. https://www.nationalsolicitors.com/mandy-peters/latest-news/banker-wins-compensation-in-noisy-neighbour-row/ https://www.jpclaw.co.uk/latest/noise-nuisance-flat-owners-beware

usually it's to limit the flat above not changing carpets to hard flooring. there are recent cases where people have done this and got fined daily until it was put right.

There will be in flats, also a requirement as part of the lease hold agreement.

If they knew the bifold had to have a level threshold they should have allowed for it when seting out the dpc / vent hieghts. I don't like the developers proposal as it sounds like a bodge and the easiest / cheapest way to 'fix' the defect. Have you asked building control what they deem the correct remedial work would be?

It should look like this in section

You do build the inner wall leave on top of the last 100mm of beam and block infills, but there has to be a supporting wall below that. The other thing that looks off is there is no ventilation vents visible going down under the block and beam floor?

Yes, he should be using concrete slips which are 40mm deep when used with a mortar bed is 50mm to fill the gap between the low part of the beams https://www.bradfords.co.uk/details-blc056

once they are shortened and on the inner leaf i would get him to paint the ends with bitumen paint to seal the rebar.

Am i being thick here, or i may have missed it. I can't get my head around this construction and this detail. An earlier drawing the OP showed is for a cavity wall along this line. Those beams should not be crossing the cavity to the external leaf. Also those beam ends don't look like they have been treated to protect the rebar from the ingress of moisture.

I will message you about this.

i don't know about that, afterwards you are stuck with a money and time sapping creation, that if you are lucky isn't a financial burden to you after 25 years! 🤣

depends on how much £££'s you take

If you are going to take on the build yourself, have a good think of the structural construction, Masonry, Timber frame (kit or self stick build), SIP, ICF (a number of forum members have done this self build)

Welcome, have you considered a full demolition as you will be able claim the full VAT back on a self build, but only 5% on a conversion. I don't know what your job is like, but physically doing your build yourself is a huge ask and very time consuming. From personal experience my plan was to PM and only do limited work on site. This ballooned out and i took on more site work that i planned to, and even the PM stuff took a huge amount of input. Just a bit of a warning to go in eyes open What are you looking to build?

nice, when are you looking for the demo and start of work. how are you looking to spec/do your build?

The noise assessment will be based on manufacturers sound power data for the turbine at different wind speeds, something like below The turbine generally gets noiser at higher windspeeds, until it hits it cut off windspeed to avoid damage. Also the noise criteria gets higher at the receptor as wind speeds get higher as the background noise level increases. However as there is a financial tie, it's a flat 45 dB whatever the wind speed. In this example the wind turbine has a sound power level of 108 dB at 10 m/s. Assuming a simple point source radiation and no other losses or wind propigation effects its 34 dB at a receptor 2km away. There will be more than one turbine operating, so you get a culmative effect but need to account fot thier spatial distance. Say 4 turbines are equally spaced to the receptor, the result of all 4 is 40 dB. 8 equally spread turbines is 43 dB. However the losses due to met and atmospheric can be large, so these levels can only get lower. When the wind is howling at 10 m/s the ambient levels at you house may mask the noise. However personally I would want a chunk of cash before I start to give up my rights in relation to noise.

Ask the developer for the noise assessment to see how noisy it's going to before you sign. If it's not a lot of money I wouldn't sign up without seeing what the predictions say. Sounds like the ones they are putting In are bigun's with sound emissions that may be pretty high.

How many turbines?

Are you financially involved? will you get money as part of the development. If you a financially benefited from the scheme you will have a reduced noise criteria applied to you (i.e. the turbines can be louder at your premises compared to someone not financially benefitted). I can't recall of the top of my head if its 3 or 5 dB. Edit i was wrong, it varies but is 45 dB during the day and night.

Mr Dunning and Mr Kruger have entered the chat....

Pretty much and have a thermal performance of about 0.021-0.022. Cooltherm is lower at about 0.019, but you pay more for that.

I am sure the dynamic sampling gave them a bit of the flavour of piling noise. How much earth do you think that you are taking out in the reduced dig? I think ours was about 400t. I hate to think how much yours will be, and the muck away cost! (Assuming you can't lose it on site)
