The 100mm svp in the corner of the bathroom is probably a stack but I just noticed it says "222 (svp)" and "572 (svp)" in the middle. What's that all about? It also says "Foul drainage - see notes" what do they say if anything?

If you already have 110mm pipe through the founds for the sinks and showers then you could replace the gully traps with inspection chambers. You would need u-bends under the basins and a trap under the shower as well. Perhaps this would mess up plans for a nice patio? Something like this if the falls are ok.. Notes: I've shown an inspection chamber in the middle as well because personally I wouldn't be happy with the buried "T-junction" and rodding eye shown originally. You may need more blank plugs than I've shown. It depends on how many branches there are on the IC bases.

http://www.legislation.gov.uk/uksi/2012/605/regulation/14/made Regulation 13 is the regulation that protects trees. Regulation 14 covers exceptions that allow work on trees...

They are very unlikely to prosecute. They haven't got the money to instigate lawsuits. My guess is they may issue some sort of stop notice or a notice of intended action (or something with a similar name). That may or may not give you a time limit to fix the problem. I would make good the tree protection ASAP and remove any concrete you can (hide the rest?). Then write to the tree officer to apologise for the inadequate tree protection measures "because you are new to this" and ask him to come and advise if the new measures in place are ok.

Bathrooms upstairs will normally feed everything into a 110mm stack. The bottom of the stack underground will have a special large radius bend to turn it from vertical to horizontal. From there it runs to an inspection chamber. Showers on the ground floor can be done several ways. The shower tray can be raised on a plinth with a trap underneath or at floor level with a "top access trap". Then the output from the trap is usually either a 40/50mm pipe to a 110mm stack. I believe there are rules on the minimum height difference between the drain outside and the shower trap. This can be an issue if the sewer in the road is quite high or there is a long run from the house to the sewer.

I think what we have is a 110mm drain that runs down the side of the house to the main. At various points along it we have a 450mm inspection chambers each of which comprises an inspection chamber base, riser and cover. The inspection bases have a straight through path and one or more 110mm branches that feed into it. This sort of thing... http://www.pavingexpert.com/drain05.htm#newic

Hi Jilly, I see in your other thread its a barn conversion of around 80sqm. The CIL only applies to developments over 100sqm. So it shouldn't apply unless you are planning an extension at same time.

They need not be external gully traps. We have traps (u bends) under the sink then down into a 110mm via an adaptor. Then under the floor into a manhole outside.

Perhaps try entering the French department number for Calais here.. http://www.bacacier.com/nous-contatcter/trouvez-technico-commercial/ The number for Calais is 62 according to google.. https://www.google.co.uk/search?q=numero+departement+calais&oq=numero+departement+calais&aqs=chrome..69i57j0l3.12649j1j8&client=tablet-android-pega&sourceid=chrome-mobile&ie=UTF-8 The huge Batibouw expo might be worth a visit end Feb. They may well be there. https://www.batibouw.com/en

CIL = Community Infrastructure Levy. It will be mentioned in your grant of planning if the council have introduced it yet. Its intended to replace the older S106 contribution. Can be a small fortune for a large house in some areas.

My understanding is that the council has the power to decide your address. They can accept, reject or change your address under legislation summarised here. https://www.geoplace.co.uk/addresses/street-naming-and-numbering/existing-legislation They can charge for this service under section 93 of the Local Government Act 2003. The above is different from getting the details onto the PAF file.

Hi Jilly, If the CIL applies in your area do all the exemption paperwork before you do anything on site. Otherwise you lose the self build exemption. Are there any conditions on your grant of planning? Some of these may have to be discharged before starting work. You don't need to apply for a postal address for the site until much later but I don't know if there is anything to stop you doing so early. We fixed up a temporary postbox long before we had an official address. You don't pay council tax until much later (unless you live on site in a caravan?). Eg after the house is habitable.

Is there some sort of boost on the night storage heater or something else that might have been left on overnight? 116 units over say 12 hours is roughly 10 units an hour or 10kw. Not many things dissipate that much. Don't think an oven would do it.

I'd just stick in another duct. I'd have three valves. One on each of the incoming and one on the outgoing to the garage.

+1 He MUST zero rate his service to you. Refer him to VAT Notice 708 section 3.3.4. I wouldn't accept his quote until it states something like "inc VAT at 0%". https://www.gov.uk/government/publications/vat-notice-708-buildings-and-construction/vat-notice-708-buildings-and-construction His work must be zero rated therefore his materials must also be zero rated. If YOU buy any materials then you will pay VAT on them and this VAT can be reclaimed. Now this is getting annoying. I very carefully checked I had quote and /quote tags in the right place and again the formatting is messed up.

Are any of the big builders ISO9000 registered? Perhaps someone should revoke their registration :-)

Looking at the process described here you will need the MCS certificate (their bold).... https://www.greenmatch.co.uk/blog/2014/12/how-to-apply-for-the-feed-in-tariff-fit Edit sorry the formatting got messed up and it won't let me fix it. Last two paragraphs are mine and shouldn't be in same quote block.

Leave doors open downstairs, although that does increase the risk of fire spreading. Electric wall heaters range in price enormously. Personally my feeling is that it's hard to justify the high prices charged for some of the more expensive heaters. In the past I have filed complaints with the ASA over some adverts and had them upheld. So I would look at exactly which heaters you were quoted for carefully. You can get some with a thermostat and programmer for under £100. There are also some that that come with feet and a plug so no installation cost at all, just plug and go. You may also find some have mounting holes on the back so you can fix them to a wall and wire them in more permanently later.

Just to echo what others have said.. That's the legal minimum they are obliged to provide, same in England. However in practice it's very site specific. In many places you actually get >3 bar. Before deciding on anything you should measure the actual static pressure on site and the flow rate you get from an open pipe in liters per min. You may not need to do anything, no pumps or storage tanks.

It sounds like some apprentice was told to allow 50mm for the ends to be trimmed and took that to mean trim 50mm off each end :-)

Check the length of the other joists. Perhaps I'm wrong but it looks like they may have taken 100mm off the length of those even though some only have a wall plate one end? For example it looks like J003 goes from a wall to a beam? So they should be 2589mm less 50mm for one wall plate = 2539mm. They have them as 2489mm ?

Ok so basically they are saying that Permitted Development Rights were removed or restricted in the grant of planning for the development. I would do two things... 1) Ask the developer to confirm that that planning reference (13/03196/FU - normally they end /FUL) is the correct one . 2) Log into the planning portal and check the exact wording of all the planning conditions on the grant. If Permitted Development rights were removed then you will need to submit a planning application. However from your description of the extension I think its very likely to be granted. While you are logged into the planning portal you might also be able to download a site plan with a scale on it to work out the distance to the plot boundary.

£23 seems to be a good price for 50m of 25mm.

It's not quite clear where the boundary is on the image in your OP. Can you mark it in red tell us how many meters (or feet if you prefer) it is from the garage wall to the plot boundary. We may also need the height of the eaves/gutters of the garage. Planning Permission: May not be needed if it meets the height rule near a boundary. Building Control: You may not need to involve Building Control if less than 30sqm AND is far enough from the boundary. In short you haven't quite given us enough information. If you can provide that we should be able to give you a clear answer.

My guess I they would scale off the drawing and see if your building was out by more than could reasonably be justified.
