Removing a fireplace/chimney stack completely

Why would you be wondering? if you're having it done by a builder let him do the wondering.

One thing, you need permission from the neighbour it being a party wall?

The stack has to be supported in the correct manner in the loft area.

-- Sir Benjamin Middlethwaite

Basically, it depends on the type of the chimney construction and possibly, depending on this, the attitude of the neighbours.

There are two common chimney layouts in 2 storey Victorian terraces.

1. Flues are in a square formation. The party wall runs right through the middle of the chimney. Normally, the chimney pots will be 4 in a square, although this is not guaranteed. The chimney breasts will be narrow and deep.
2. Flues are in an inline formation. The party wall does not run through the middle. Your flues bulge into your neighbours property and, crucially, their flues bulge into yours. The chimney pots will be 4 in a line, although this is not guaranteed. The chimney breasts will be wide and shallow.

Basically, you can remove type 1 above without permission from your neighbours. It is a big job, but emminently doable and commonly done. It will need building control approval. The stack above the removal will need support using beams or gallows brackets to the approval of the BCO. The floor support and surface will need rejigging.

Type 2 requires that your neighbour provides permission, as you will also be implicitly decomissioning their flues. If they also want to remove their chimney, then you could split the costs and remove the whole thing. The job is much more substantial, however, as during removal, there won't be a party wall in place, so one will have to be built and support given to the rest of the house.

However, luckily, because the square formation is the most bulky and deep and less elegant, it is normally the type people object to enough to bother removing...

No you don't need permission from your neighbour to do it whether it's a party wall or not.

However, you would have to comply with the party wall act if it's on a party wall which is a different matter entirely.

(b) where the work is to a party structure or external wall, subject to carrying any relevant flues and chimney stacks up to such a height and in such materials as may be agreed between the building owner and the adjoining owner concerned or, in the event of dispute, determined in accordance with section 10

-- Sir Benjamin Middlethwaite

Er, maybe because he hasn't got a builder because he hasn't yet bought a property?

Simple answer is yes, it's a lot easier said than done: properties vary of course but generally a chimney breast/stack is pretty integral to the house, and removing them needs care to ensure everything remains properly supported. Potentially pretty expensive I'd have thought.

From an aesthetic point of view, I'd leave well alone.

Indeed. You don't need their permission. If they attempt to withhold it, it will be granted by a court instead. However, if their flues intrude across a straight dividing line between your houses, it doesn't give you a right to pinch their property and close off their chimney!

This is costing money is it woth it?

(b) each party shall appoint a surveyor and the two surveyors so appointed shall forthwith select a third surveyor (all of whom are in this section referred to as "the three surveyors").

-- Sir Benjamin Middlethwaite

Nope. Far better to get in quick and do the work before an injunction is issued. It is a cheaper method. No penalties are specified for failure to obey the Party Wall Act. IANAL etc. etc.

Just obey the spirit of the law by doing the job properly, using a structural engineer with insurance and fix any damage done to the neighbour's decoration with good grace.
