Dreadnaught

Welcome for BuildHub @TomBee. I am south of you in Cambridge, just at the point of starting my build. Good luck with your planning!

What is AGD? Google suggested it was wither Agricultural Drain or Australian Geodetic Datum.

@Dan F, I wonder are planning using timber studs or metal framing for your internal walls? (I have chosen metal framing).

I'm interested in this too. Had chosen a Sunamp Uniq12 for my build but am now wavering. Will be interested to hear what you choose.

Thanks @Thorfun. Likewise! This is the scheme: https://gigabitvoucher.culture.gov.uk. A voucher is arranged by the ISP not the final user. I was able to get one by working with ISP and by showing that I work from home, which entitled me to a £2,500 voucher, whereas the more usual one is just £250 or so. My advice would be look for small local broadband companies installing fibre and talk to them. I made a list of the local ones in my city, Cambridge, and might have just been lucky to have found one keen to connect me and a neighbour up. I have heard the scheme is changing so I recommend being quick. In fact it might have already closed, although I wonder if there will be another scheme to replace it. I visited them and Velfac (which is related to Rationel). And I am familiar with a few other window manufacturers, like Gaulhofer, InterNorm and Norrsken. I am not one to spend ages agonising over such a choice. My choice of IdealCombi & Velfac over the other manufactures was purely because the of style of window frames, which appealed to me. And once I had chosen the windows, it seemed sensible to include the front door too. In terms of quality, they seemed fine to me but I don't consider myself an expert as these will be the first windows I have ever bought. In comparison to buying other things for may build, such as the roof windows, Ideal Combi (and Velfac for that matter) were a breeze to work with. Very efficient, helpful and quick. Easy to negotiate with. And I also thought they were good value for money. I've seen your other thread inviting comments on the front door, which I am following with interest. I can't explain the price difference other than with a slight suspicion that other doors may have slightly better insulation and wider range of fittings. Only a guess. I suspect perhaps the biggest issue may be wider margins necessitated by a different sales model using local agents. Hope that helps.

That's an interesting approach. I like it. To add to this in my case, as a novice in building, I also want to try everything* at least once. There is nothing quite like being hands-on to really learn about something. Moreover, this would then put me in a much better position to know what's-what when I have someone else doing the job in exchange for my money. * with well-known exceptions, like plastering, brick-laying and electrics.

Another important difference between full fiberoptic solutions and wired solutions, which I believe includes most of VirginMedia services that inherited the cable television coaxial infrastructure, is much increased reliability of the connection. I learnt about this when arranging my FTTH solution for my forthcoming build. I wonder if others agree with this advantage for fiberoptic.

Wine cellar maybe

Find someone with soil muck-away nearby and offer to take it free-of-charge (delivered)? It could save them the disposal cost.

Welcome to BuildHub, Julian. I am not too far away from you in Cambridge. I have planning permission and will be starting my build in the coming months. Good luck with your planning permission, there is a wealth of knowledge on here.

In addition to "liability for damage to site or neighbouring properties" which you mention, there is also third-party liability relating to human injury and death. This is a huge issue which I think should be very clearly defined. Will the TF company have full control of the site during their phase of your build, for example? It is linked to CDM 2015 of course. I think I too would want a contract for such a major phase of work.

I will be choosing GU10s, and fitting them with Philips Hue GU10 bulbs to provide lighting automation. The idea is that if I sell up the incoming buyer does not want (to pay for) them, I can take all the Hue bulbs with me as I leave to the next place.

The type of insulation is not specified but I had assumed it was PIR. As I understand it, the inner leaf of insulation is intended to be continuous with the insulation inside the rooflight frame, and forms a thermal break. The weight of the rooflight is supposed by a combination of the exterior box frame and the interior single free-standing piece. It took me quite some puzzling and chat with the rooflight company before I worked it out. In reality, I don't think we will follow these details too closely. Instead we will make something simpler but still much thicker than the typical upstand (including the one typically deployed by my timber-frame designer). In my case I have nine rooflights, and almost each one will require a different upstand. Quite a complex design job and probably the only part of the overall frame design that really does require 3D.

At the sole plate, for my timber frame we chose to split the sole plate in to a pair of battens, rather than a single piece of timber, so as to eliminate the cold bridge there. In my case I am having I-beam walls which will pumped full with cellulose insulation. (I'm having an insulated raft foundation.)

I am designing the upstands for my rooflights now too. Mine are from a different company but are also triple glazed and are passive-house certified. I also have a PIR roof of similar thickness. This is the upstand detail that I am following but my timber-frame designer and architect are converting it into something buildable offsite by my timber-frame manufacturer:

Not helpful to you, but I saw one other exact example of this when visiting other builds. In this case it was for patio doors from a bedroom leading on to a flat roof. In that instance, the warranty company chose to specifically carve-out the issue from the warranty cover. I think the self-builder chose to continue without any remediation of the problem and I haven't heard whether the issue has subsequently caused problems.

More generally, and not being any form of expert, I found that having a (paid) M&E adviser in the planning stage of my build has proven to be invaluable. A few hours of hourly-rate advice from an expert has impacted on so many areas, not only the choice of a heating system, but everything from penetrations through my concrete raft, to lots of other issues that had knock-on consequences elsewhere. I had picked up a great deal of knowledge by avidly reading this site (thanks everyone!) but that adviser was able to assist in unpicking all of my half-thought-through ideas and string together a coherent concept. I considered it money well spent and my architect complimented me on the approach.

I am at the stage of discharging planning conditions so I can start. It has taken almost 12-weeks and I have only just had the first one discharged (of nine). I have just sent them a two-week "deemed discharge" notice for the rest, which might focus their minds (… or might not). That's an indicator of how slow things are in my neck-of-the-woods (Cambridgeshire).

Did anyone keep a copy of this example letter above ↑. I cannot seem to access it any more and keen to prepare my own letter now.

An iron-age roundhouse on wheels maybe? And only need to comply with the static-caravan requirements. Commendable aspiration. (I remember the 1970s BBC series too).

"LoopCAD is a Windows program only". No Apple Mac support. ? I wonder if there is a friendly LoopCad-user out there who could see themselves willing to help a wretched and neglected Apple Mac user? Would love to design my loops. ?

Off topic (sorry), what is "facing"?

@Field_of_Dreams, yes. On all of those points I turned out that it was possible for my tree specialist to draft the Method Statement to accommodate whatever I wanted. I was quite surprised and pleased. It seems almost anything is possible and, so long as you choose a good expert, he can make almost anything work. I do not know if all of the tree experts are like my one, but he was recommended to me by another self-builder as someone who would "be on my side", which I am now coming to appreciate.

Hi @Field_of_Dreams, oh yes, what in particular interests you. In general I have found that most things are possible, they just need to be framed in the right way for the council tree officer. And moreover, its all well and good to have a detailed arboricultural method statement (AMS) but I get the impression that the reality on the ground is likely to be flexible. Having said all of this, I am still waiting for the council to sign-off on my planning conditions, which includes the AMS that was drafted for me by my tree specialist.

The piles support the entire insulated raft, across the full floor area of the dwelling. There is no separate ring beam. The raft has the edges thickened, which act like a ring-beam in terms of supporting the exterior walls. And because the majority of the raft will be quite thin by the standards of concrete foundations (just 100mm for most of the raft) there will also be reinforcing cross thickening to form structural ribs in key areas. I have also specified in my build that none of the internal walls be structural, which is quite easy to do as mine is a bungalow, and gives great flexibility.
