Adjoining Owner
Is your neighbour planning building works?
Is your neighbour planning to undertake:
- A rear or side extension
- A loft conversion
- Chimney breast or stack removal
- Basement works
If so, under the Party Wall Act your neighbour is obliged to serve a Party Wall Notice upon you prior to commencing any such works. The Act provides Adjoining Owners with protection if there has been any damage caused to a property which can be attributed to the Building Owner’s party wall works.
Squarepoint Chartered Surveyors assist and advise Adjoining Owners on all party wall matters. We can act as your appointed Party Wall Surveyor.
