Neighbour stole loft space for conversion

Another_Level

Yes the property can be sold like every transaction its 'buyer beware'  further (paid) investigations can take place but its being sold as a property where the sellers have no knowledge of the property (unless the inheritor knows more) .

Maybe tell the neighbour property owner ask them if they want to buy your property, hey make like easy

I think you need to discover which of the two side walls line up with the walls below.

From the second picture it looks like the wall on the left is the original wall and when the builders have created the conversion they've moved the wall on the right hand side further into your loft space.

Bloody hell they have definitely stole your loft space and are they even allowed to knock down which looks like a retaining wall?

I would get building control out for advice and get their opinion.

After that a sledge hammer and a few quid on a tradesman would solve the problem, which I would then sue for. 

You want to go legal, that's a long drawn out and expensive process.

I agree with this, it’s an important first step. Once you’ve established that you can plan on what to do next.

Did you not hear them doing that work? If it was above your house with only some plasterboard in the way I’d have expected the noise to be significant.

It's an inherited house

There are quite a few on here taking running jumps to, I believe, the wrong conclusions.

The photos so far do not prove anything.

OP you need to get your measuring tape, pencil and paper out and draw a bit of a reasonably accurate plan of the loft and the floor immediately below.

Wow that photo is an OMG moment!

Maybe it's not as bad as it looks. As said try to find out exactly where your walls are below just to be totally sure before you go further.

Have you asked the neighbour about it and your concerns? He/she may be able to explain.

Do let us know what reason they give.

The two brick walls look like they exist only to support the timber purlins of the roof. Houses of this age were typically built with an otherwise open roof space throughout terrace with only one house having access. It certainly sounds like the neighbour has taken this without agreement (or perhaps has taken advantage of the now demised elderly owner). Do you have legal cover, it might be required.... Last thing you want is a flying freehold.

Would be interesting if the owner  " tripped over in the loft " and went through the plasterboard ,even if they have permission to build it should it not be protected by a brick wall ,if a fire started next door in the bathroom it would spread quickly into both houses .
