Post and beam

Also building soon in Hertfordshire, off a country lane. I spoke to UK power networks just this week and theya re sending a surveyor on wednesday to quote for the temporary supply & subsequent house supply. No cost for this survey and they will provide a written quote. No brainer really just ask them to come and survey your plot. I dont know about water, they have not responded yet.

Possibly, yes. But having said he was experienced and then later in the conversation exposing the fact that he actually was not i think i am justified in letting the gentleman pass.

I wish. More like about £5k now. Welfare facilities for the archealogists. Open ended upwards from £5k if they decide they want to do more. One firm wanted to reserve the right to call a sight meeting with the county archealogist at £95/hour billed to me when and if they decided to do so. You will understand why i am wary of the whole circus.

Just to be clear, the village is already an area of archealogical interest. Dont know who decides that but it means a desktop survey wont cut it. It turns out that the convention the county uses ( Hertfordshire) is 'trench 5% of the area of the site in the area of the footprint of the project'. The people i have consulted are aware of this but i was not. They have to submit a written submission of work ( the WSI) it gets approved by county, they dig the trenches and we all hope that nothing is found. Guiding principle seems to be. Anything found will likely mean more work is required and i will have to pay for it, and accept the inevitable delay. They decide what needs to happen with no recourse from me and i just write them a blank cheque.

I agree, up to a point. If the guy puts himself forward as competent then i expect them to be.

I asked a prospective builder about ASHP and MVHR. It was clear from his response that he thought it 'new fangled technology'. In my head the meeting ended at that point. He was a nice genial old boy and i am sure he could build me a solid driveway. Just not the house. I am still looking

Obviously the type of seal on a sliding sash window is going to be less effective than a traditional casement. But how much less effective? I have been investigating masterframe sash windows, they look good. But if they are not compatible with a highly airtight build then i need to abandon them as an option. Is anyone else using them and achieving good ACH figures or is the whole idea stupid?

How much? That was meant to be an exclamation of shock not actually a question.

Or get someone like Potton to turn the planning drawings into something that can be built. Although Potton are relatively expensive they would do all that is required to get the thing built right.

When the power company surveyor arrives i want to be as informed as possible. Do i need to ask for/demand a specific current capacity. EV capability or anything tht i am currently ignorant of. The house will be a 200m2 detached. I need an ASHP. If its not too expensive i might request an EV capability. Is there a specific location in the house that the CU has to go or is it down to me. What have i forgotten? Thanks in advance as always guys

Nice rendering

Yep, complete Bo!!ox. Is it likely that architects designed ' just enough' strength into Multi storey car parks.

Do you have a leak? Dirty water sounds a little worrying

Well there is the problem right there. Easy to say, not so easy to find one which is my issue in a nut shell. Since i posted last night i have e mailed 4 installers from the .gov website of accredited installers. Lets see what transpires Agree. Thats why i cannot see the £10k ish fee for doing so.

Fogg What i can say about my Potton experience is that the planning permission submission that they talk about is not part of their house design service. It is a referral to agents of theirs and cost me £2.5k. Then £6.5k for trial pits/foundations design.

I am having a Potton House built soon. Have planning permission and a design from their older style range. A couple of others on here as well. Your design is very modern looking.

I am starting to despair of the whole ASHP saga. See the Chelmer thread. £12300 + VAT for supply only. We all know that the parts are available to buy and what they cost. I am not capable of doing this job but there clearly are people that are. Where are you all ?

Its 201m2 when built. I dont believe it will need that size of pump. Yes it is. I am beginning to despair of this whole racket.

I have had a quote from them today, initiated out of this thread. ASHP(SAMSUNG 12KW) 350L cylinder, UFH hardware and a few design bits and sundry plumbing parts. Dont understand the plumbing bits but i'm sure they are necessary. £12300 + VAT supply only. So, very nearly £15k

Thats a real shame for the OP. My 'standard' permission requires start within 3 years. I asked, and digging the footings is the minimum recognised as starting.

No trouble at all actually. 10 weeks total, from submission to full planning. My sister and brother in law had permission on the same piece of land in 2016, that never went ahead. At that time east Herts were particularly difficult apparently. A single person by all accounts that has since retired. My brother in law was so worn down by the process that he accepted all of their restrictions just to secure some kind of permission. Smaller and simpler than he would ideally have liked but he was afraid to argue with them(Her)

Intrigued to know where but perhaps you dont want to say. We have recently got our planning permission for a house in Aston. Good to see a fellow Stevenage resident on the forum. Welcome. Can you just dig the footings for the permission which stops the timer doesn't it? And submit your extended application. Then, either way you wont run into the 2 or 3 year time limit.

Guys, i am not saying that they are unreasonable at all just putting the info out there. It does not suit my situation for the reasons i stated in my first sentence. This is the condition i have with my TF supplier and the timing. Not complaining about the TF company either, its just a co ordination issue for me.

They have so far declined to get involved. By the time i have the plans that they want i will have needed to make the call on which pump i need. In order to successfully quote for this property we would need you to provide architectural plans detailing ceiling heights, room dimensions, insulation, underfloor heating schematics showing pipe-run centre measurements and locations of manifolds, proposed floor finishes on UFH areas eg., Laminate, hardwood, ceramic tiles etc., proposed location of all radiators, glazing specifications and sizes of units of windows and doors, proposed site of ASHP and hot water cylinder, roof surface eg. Tiles etc. We would also require details of the electrical supply eg 1phase/3phase? Also we usually wouldn’t be able to design the hot water part of this system without knowing the standing and working pressures of the mains water supply as well as the flow rates of the water. We would need you to meet us on these requirements as we cannot specify an ASHP kw output for your property without calculating a full heat loss calculation for it.

Following the 'slow and low approach' to planning the UFH and Heat pump for my upcoming build i believe that close pipe centres at as low a temp as practical is the way to go. So, if i go with 100mm centres i doubt that i can accurately( if at all) lay the pipes required to a neat pattern. Not without the castellated panels anyway. I priced these this morning and it looks like it might be about £1.5k just for these. I understand that UFH installers are generally not keen on close pipe centres because it takes too long to lay. Does anyone know if this is actually true. Even if it is i think it might be better to just pay them what they need to spend the time to ensure a good job.
