Most people find the thought of coping with party wall issues a daunting prospect. The Party Wall Etc Act has many connotations, so it's no surprise that lots of people have problems with it.
Daylight Analysis Wandsworth can become a lot more convoluted in major cities like London, which have many period properties and buildings near each other. It is essential these issues are dealt with properly.
Explaining the Party Wall etc Act 1996
The Act provides rights and responsibilities whichever side of the 'wall' you are on. For the party undertaking the work the Act offers rights not afforded by common law, such as access onto the neighbours land to handle some or all of the proposed works, or provide temporary works (e.g. scaffolding) during the course of the works.
You should understand the Act whether it is you or your neighbour who proposes to handle work on shared or close by structures. The Act covers work on structures such as for example shared walls, floors/ceilings of flats, garden walls, and excavations near a neighbouring property.
The overall principle of the Act is that all work which might have an impact upon the structural strength or support function of a party wall or might cause harm to the neighbouring side of the wall must be notified.
Some of work included in the Act is the following:
Demolishing and/or rebuilding a celebration wall.
Increasing the height or thickness of a PW
Cutting into the PW to take load bearing beams.

Underpinning a PW.
Excavations within 3 metres of a neighbouring building where in fact the excavation will go below the bottom of the foundations of the neighbouring building.
Excavations within 6 metres of a neighbouring building where in fact the excavation will go below a line drawn 45� downwards from the bottom of the foundations of the neighbouring building.
Work that is not covered by the Act includes adding shelves and wall units, replastering and electrical rewiring.
If your planned work on a preexisting structure falls beneath the Act, you need to then issue a notice to all affected neighbouring parties. The neighbouring parties must then decide whether they wish to dispute the notice or not.
As with all work affecting neighbours, it is always better to reach a friendly agreement. Even where the work takes a notice to be served, it is best to informally discuss the intended work, think about the neighbours comments, and when practical amend your plans accordingly.
