Rear Extension Wall

[may1day]

I have recently moved - the property has a rear extension . So in effect it runs between me and neighbouring property . She has now told me that she intends to erect conservatory and use the out side wall of me extension as a jack wall for her extension. It would be then an inside wall in her house an she would get in plastered. I not happy in case I ever wanted to pull in down or a future buyer.
Would like to know what a Jack wall is

I would think it's a supporting wall.

[woofgang]

whatever it is, you own the wall and she can't just use it without your permission.....which i would think long and hard before giving

[TWR]

To add, I would object, if you ever sell your house you may encounter problems due to the wall.

If the wall is within your boundary tell them to build their own wall.

[murraymints]

Tell her to go forth !

There’s no such thing as a jack wall. Are you sure they didn’t say ‘back’ wall?
Anyway, as already said, if it’s on your land tell them No! If it does go ahead, they will need to do a party wall application. That might make them think twice.

I've heard of a "Jack stud" - which is found around a door opening in a timber stud wall, but I've no idea what she means. No matter, I guess she just means a back wall to her conservatory.

She can do nothing without your complete agreement. In fact, even for a conservatory, I think the "Party Wall Act" would have to be invoked before anything could start.

Ah... Zacs snuck in there ;o)

A couple of questions.

Are your properties ajoined eg semi detatched or terrace? And does your extension wall also act as the boundary between the two properties?

[may1day]

The properties are semi - so in effect the fence continues down the line of the extended wall

[woofgang]

maydup, walls, like fences, can mark boundaries, but they don't act as boundaries....remove the wall and the boundary remains

[Maydup]

In which case as already mentioned, Party Wall Act will apply, as will planning permission. Both of which you will be able to oppose, but no guarentee of success.

I suggest you tell them that you'd most likely oppose any such development and ask if they can avoid that design. However, you might have to concede as your extension has got there first and plonked itself on the boundary, which leaves them little option but to build onto it, just as the houses are joined, the extensions will be too.

Fairly recently I was asked about the idea of building a conservatory style reception up against the neighbours detached property.
After a bit of research we found we needed to leave a clear metre between both structures. This one metre would allow the neighbour access for maintenance.
The party wall act as previously mentioned is all about boundaries.

[may1day]

I have checked now and the extension wall is inside the boundary still don't know what a Jack wall is but I will have to find out now how close she can come build to my wall

[woofgang]

don't just check how close she can build to your wall, also check how close she can build to the boundary between the properties.

This scenario is exactly what the party wall act was designed to look into.
