One other question. I am going to mount the grp kiosk within 3 ft of the pole where they will bring the feed from. What I'm not sure about is the additional 100mm ducting that they mention. They mention for split phase you need to install a 50mm hockey stick to a depth of 450mm below FFL. It's the section from the hockey stick to the pole that I'm not getting. Does the SWA cable that they will install also have to go into some sort of ducting?

What do people mean by "black hockey sticks"? When I met SSEN onsite, he said use 100mm ducting from the kiosk to the pole. I thought that seamed a lot. We are having a split phase connection. Also. Where are people buying the kiosks from?

Brett Martin drainage seems quite readily available online and I was wondering what thoughts people have on the quality. I have read that Wavin and Floplast are also very good, but I'm struggling to find online sellers who also sell perforated pipe. In a separate topic, I've seen very large price variations on 110mm underground drainage.

In case anybody reads this thread in the future as they too want a raised outlet, here is the drawing that I finally received from one of the Graf reps. A picture speaks a thousand words. One2clean with Raised Outlet_ Specification.pdf

Mortgage offer received from Hanley Economic 1st August - 5.85%.

The problem is now resolved. Graf are pretty useless when it comes to their online documentation and the various configurations of their tanks. It was only when I came across a web site selling them, did I realise that there are actually 4 outlet configurations. Every other site just lists the tanks as 'Gravity' or 'Pumped' outlets. So you can raise the outlet by either 300mm or 515mm with the standard lift system that comes with the tank. I was just about to hit buy on a pumped tank. Having a raised outlet helps as it means it puts my drainage field above the fast draining chalk layer and into the soil layer that gives me a > 12 Vp reading. This not only saves a huge amount of excavation, but also having to put a 700mm sand layer underneath the drainage field to increase the Vp so that it meets the criteria.

You can get a level invert chamber. The below would work.

450k

Seems strange that they want an IC. The tanks all have internal sampling chambers so unsure why they want one. Did they give a reason?

I am trying to deduce the junction below and how best to do it with 110mm soil pipe. I want the flow to go in both directions, but didn't want to use an inspection chamber. It's the pipe layout for a drainage field.

I didn't twig at the time, but the valuation performed by the mortgage company valued our plot at 250k (bit of a shock, given I paid 350k) and they valued the house at 950k. It's a 200m2 property. I didn't think too much of it and went and purchased the site insurance / self build warranty on the basis of the figure from estimators online. Namely 350k. I then get an email today from the conveyancing solicitor telling me that Hanley want the site insurance and structural warranty increasing from 350k to 700k. No problem, I said, it will only be a few quid. Cut a long story short, it's another £2800 Moral of the story, make sure you push back against any overinflated valuation of the rebuild cost. 700k to rebuild a 200m2 with an attached garage is a complete joke, but I am not sure if there is anything I can do about it.

Thanks @Gus Potter for taking the time to respond with such a detailed insight regarding the bending characteristics of masonry walls and whether they provide the required structural characteristics for a cantilevered staircase. Given a steel structure appears to be the best option, I'm keen to understand more.

I need to order some stuff, so I can finally get started on site. First job is to get a hardstanding down and the second is to install the STP and drainage field. Can anyone tell me what type of fabric I need for the two jobs as I am not sure?

That to me is disgraceful and I am surprised it's lawful. If it's a self-build, then it's exempt. Incorrectly completing a form, should not make CIL exemption null & void.

I agree, but if the sub floor structure is as follows, then the soil pipe needs to be buried below the layers in the diagram below? This will then dictate that the invert of the first IC 28 metres from where the tank will be located?

No. It's the unit where the invert level of the outlet is higher than the inlet. It has a pump that then pumps the treated water to another tank higher up.

You think they would look at the submitted drawings and see that there is no change to the buildings proposed footprint.

Thanks

I was just looking at invert levels again today and as the soil pipe run is 28 metres from the first inspection chamber. The invert levels are as follows. 1:40 - 1340mm 1:60 - 1110mm 1:80 - 990mm This is because the first IC has an invert of 640mm. I don't think I can do anything about that as the slab floor make up of concrete/insulation/sand blinding/harcore is 500mm, add 110mm and you are at 610mm. I assume that the soil pipe has to go under the type 1? The reason for my post was that I was considering going with the Graf pumped option as it would mean the 8m * 4m field that I need to excavate will be 500mm higher than if I went with the gravity outlet option. Just wondering whether the pump will be loud.

I submitted the VoC last week and today that have come back and requested I complete the CIL form again. The question is not very clear and I am unsure whether I tick yes or no. The internal floor area is not changing and it's some minor fenestration changes, reducing the driveway width. Here are the questions c) Does the application involve a change in the amount or use of new build development, where the total (including that previously granted planning permission) is over 100 square metres gross internal area? Yes No d) Does the application involve a change in the amount of gross internal area where one or more new dwellings (including residential annexes) are to be created, either through new build or conversion (except the conversion of a single dwelling house into two or more separate dwellings with no additional gross internal area created)? Yes No If you answered 'Yes' to either c) or d), please go to Question 5 I did tick No for both, but the wording of c is not very clear(not to me anyway). I assume they want to know whether I have increased the m2 of the house?

Are you able to elaborate or show me an example of a connecter?

I did think of that, but was unsure whether that would meet building regs.

I want to rework the proposed foul drainage for our bathroom as I currently don't like it, but unsure how I handle the WC shown below. I am not sure whether I could simply run it under ground and into the proposed stack shown in the right hand corner of the plant room, or whether I need another inspection chamber outside and stack for it. I wasn't sure whether I could have a stub AAV concealed in the unit that boxes in the wall mounted pan frame or whether the stack would have terminate in the attic. if that is the case then I will need to reduce the width of the window. The Technical Architect has proposed the below, but I think it looks **** and pushes the tray out. I also don't like the door into the bathroom My proposed solution was the below, but that with the boxed in toilet frame might also look naff. It was reworked at the last minute as access to the plant room was from outside and this then meant that although the plant room was inside the thermal envelope it apparently isn't treated as such and the walls needed to have 200mm of celotex. This then made me think that accessing it from the downstairs bathroom made sense. I did think to have the door in the downstairs playroom, but that is actually a proposed bedroom.

Ideally, no more than 7K

Cantilevered would be the ultimate aim. But it's achieving that without breaking the bank. My plan was something like the following. Ideally, getting the metal structure to counter the forces being applied as opposed to the wall having to do it.
