I don't know but be careful. If you do by any chance ring the council cil dept to check. Make sure that you get them to put in writing whatever they say to give you some protection.

If it was raised 20 years ago, i would be taking the level from the ground as it is now.

I had to pay the 5% on a conversion from commercial to residential.

As Bitpipe said, worth a conversation with building control. I had 4 soil pipes and they all terminated in the loft space with an AAV. The recently qualified BC officer said One of them had to be to open air. I argued that as i together with 9 other houses were all on the same adopted waste service, that i didn't need to vent to air. She insisted i did. The chief BC officer got involved and said he saw my point, but insisted that as i could not control those properties, i had to have One of my soil pipes vented to air.

Dacorum are difficult. It's where i live. Can i ask, was it a straight refusal from the planning officer ? did you have the support of the Parish Council ? I had a very hard time with Dacorum for a replacement dwelling in the Green Belt. In the end my final application made it to the Council planning committee. My thought was, here we go, a bunch of old crusties. I was surprised that the councillors were relatively youngish. It went through with only 2 councillors abstaining from voting (my local councillors) All the others voted Yes. Dacorum have been farming out applications to a private firm recently. I spoke to that firm of planning consultants before my application went in, (One of my friends is friends with that planning consultant.) He told me that after looking at my plans briefly, he would refuse it. A neighbours 100m from me, did similar to me. Lawful dev certs for extending on both sides, and a neighbourhood consultation 8m rear extension. He then went back in to knock and build, and got an outright refusal. His was farmed out to the private firm. (the One i mentioned) May i ask, is your land Greenbelt ?

I cant help, but i want to know how big. Two people, Four people ?......Hope the floor is strong enough to take the weight. Sounds like fun.

The very light shade needs to be way more Prince. Other than that, looking good.

Under the ridge tiles, unless you are very short of upstand height. Over will look like a right bodge.

Permitted devl rights are removed in my case when the new house is built .

No the external finish would be the same as the planning permission, just the extra insulation would make the house slightly bigger.

I've got some posh Harmen Karden thing that is freestanding (Bit like a Late 70's boom box) My son in Law got it for me before he left the R and D dept. The retail cost is about £600 quid. I have not used it yet, but heard his. I doubt a combined ceiling light, cum speaker could match it. If a freestanding job fails, it can go in a bin and be easily replaced. One of those failing in a ceiling would be a right pain to swap out. (Trying to find something to fit the same size hole etc)

Unless they want me to rip it all off cause me house is bigger than me permission

Finishes would be the same, just the extra insulation would make it that bit bigger than permission. So thats 2 votes for just kin do it. Cheers Peter.

So that's One vote from Conor to just do it. Cheers fella.

If you own a house that is say 10m wide x 10m deep, and you wanted to add insulation to the outside say a 75mm wrap on all sides. You would be increasing the size of your house to 10.150 wide x 10.150m deep. I believe that you could do this without planning permission. ie: under permitted devl rights. If however you had permission to build a new house at 10m x 10m and had all you building reg drawings etc done, and although the new house would meet building regs you had a thought about making it even better for future generations. So you looked at putting an extra 75mm wrap of insulation around the outside. This would enable you to smash the current building regs and get quite near to passive levels of insulation. How would it be best to approach this ? 1. Just do it, and risk somebody spotting your house is slightly bigger than it's permission. 2. Have a word with the planning officer, and see if you can do it as a small amendment (Non material amentment) ???? 3. Go back in for planning. (not an option due to objections and having to go to committee) 4. Not bother, and just build it to regs. I don't want to add it to the inside due to reducing the floor area Ant thoughts ??? Cheers folks

I don't bloody care Conor. That was still cheap as chips you git.

You lucky git Conor.

Just make sure they put the extra adhesive in the right area, so you end up with a level floor, rather than a 2mm difference between the Two areas ?. Well i thought it was funny.

That foil tape sticks very well to the foil on the PIR. I bet that whatever you coat the concrete floor with........That tape wont stay stuck for long.

Don't know about you Scotties, but down south all the muck away lorries are loaded by weight not volume. The lorry goes BEEp BEEP when the weight is reached. So getting rid of dry spoil in the summer is much cheaper than wet spoil in the winter. £350 + vat where i am for a load.

I would be leaving them 600mm max. Enough room for a not too fat builder to get in an make any repairs to the section of wall on the ground floor in the future. If at some point in the future they want to do some work on their wall higher up than they would still be able to do it. A scaffolding company would span your extension from the front to the back, no problem. And i would not be allowing them onto your land, without a full method statement, insurance in place to cover any damage to your land or property, and i would ensure that the insurance covered anybody who they employed to work on there house. I'm sorry, but you are allowing yourself to be bullied. Your extension would be much better a further 200mm wider.

There is no stipulation as to how much space you need to leave, them 800mm is more than enough. Nobody is going to make you take down a building that is completly on your own land.

If you are putting a lot of glass in your extension, you might need to have a sap calc done. If the glazed area of your extension is more than 25% of your floor area - windows and doors that you are taking out of the existing rear external wall, (putting them inside the new external envelope) then you will need a sap calc. The level of PIR in the roof will have to meet building regs for an extension. 100mm won't do it 150 or 175 might. 200mm defo should. There is no way i would put the steel within the roof structure. That is a poor idea.

That would be a fantastic addition to your house. You are not going to be made to take it down.....Your neighbour is just a bully.

I don't know Mike, but One thing i do know is make sure you get regularised timber. When i did my posh shed, i didn't, and the thickness was up to 5mm different. A right pain. I bet the BS Ones are twice the price.
