House Extension advice!!!
All,
Does anybody have any knowledge of the following.....
We're looking to build a single storey extension (kitchen/diner/garage) across the back of our 1950's Semi (by happy chance also creating
a more comfortable environment for the kitcar ).
Our (attached) neighbour also has a single storey extension (built before we moved in) and other houses in the area have had extensions built so not
expecting any real problems in the PP department.
The question is - how close can I go to the neighbours extension??
I have made some rough measurements and as far as I can tell, there's is pretty much up to the boundry (by halfing the approx thickness of the
party wall and measuring from a reference of the kitchen window).
Any thoughts??
Martin.

Firs thing to do is check through the deeds to your house and see if there's a party wall agreement.
If there is, you own the wall on your side and can build straight off it. If not, speak to your neighbour and see if you can form an agreement.
It'll save a bit of complexity in the build and also som money too (plus you gain that little bit extra space on your extension too).

From a purely technical point of view, you want whatever you build to work.
That means that the detailing of the roof at the junction with your neighbour has to be spot on, as does the way you construct the outer leaf of the
wall at that point.
Then there are the foundations. The foundation generally has a scarcement which is equal at both sides when viewed along the centre line of any wall.
That will influence how far out you can build. Doing anything else will eccentrically load the foundation or involve a more complex foundation than
you might want. When it comes to specification, I usually go for the simplest approach, so that anyone can build it. Start geting fancy and general
builders sometimes get a bit lost. Sometimes - not always.
You must be able to maintain what you build, so that's just as important.
Thinking about these issues, what form does your neighbour's extension take.
Also, how would it influence what you would / could build ?

As you want to put an extention on a semi and the neighbour already has one, their extention wall if it has no windows or doors should be an extention
of the party wall between your properties.
You will have to talk to them and probably consult a solicitor but should be able to build on to it, foundations could be interesting but a good
builder will have come across this situation before

Firstly, thanks for the replies!
We already arranged a party wall agreement with them when we had a loft conversion a few years ago. I'd have to dig it out but it was drawn up
mutually without using a solicitor.
Their extension is flat roofed and extends about 3.7m.
We were thinking of at least 4m with a flat roof so tying the two together shouldn't be impossible.
Just to add, the neighbour has just called round and we mentioned what we were thinking of doing and the first thing he mentioned was tying it to his
and using the party wall so things are looking good so far.
The last thing I want to do is upset them as they've been really good neighbours so some care may be required when it comes to the foundations.
But as you say, nothing that hasn't been seen before.
Many thanks for all the advice.
Martin.

this makes sence
I know that this might seem daft, but contact your local building control officers. It is likely that at least one of them, probably more than one,
will have a sideline doing drawings for extensions, they are cheaper and know the regulations inside out and generally point you away from the problem
areas involving this type of work.
As long as you have a good relationship with your next door neighbour using one of these guys should smooth things along

Depending on the size and position of the extension you may not actually need planning application... I just had a single storey kitchen extension
(2.5x4m) put up without PP....
See if you can find some decent builders who you can actually talk with... get them to have a look and see what they think is possible... Then just
submit buidling regulations notice and get on with it :-)
