Around the National Trust's Dunham Massey estate, historic cottages and farm buildings sit in conservation areas and the Green Belt, so extensions need planning, heritage and party wall advice together.
Much of the area is Green Belt, which limits the size of extensions.
Dunham Massey area stats on Near MeHistoric cottages, farmhouses and converted farm buildings, often attached, around Dunham Town and Dunham Woodhouses, with larger homes on the edge of Altrincham.
Which home improvements need a notice under the Party Wall etc. Act 1996
Needs notice if you build a new wall on or astride the boundary, or dig foundations within 3 m of a neighbour's building and deeper than theirs.
Side returns and wrap-arounds usually sit on the boundary line and need new foundations right next to the neighbour's.
Cutting steel beams into the party wall, raising it or removing a shared chimney breast is work to a party wall.
Digging below your neighbour's foundations, and underpinning a shared wall, are both notifiable.
Foundations, piling or deep drainage within 3 m of a neighbour's building, or within 6 m for deeper digs, can need notice.
Inserting beams into a shared wall, cutting in flashings or taking out a chimney breast on the party wall.

Often. Repairing, underpinning or rebuilding a party wall is work under section 2 of the Act, and needs two months' notice to the neighbour unless they agree in writing.
Often, yes. Under the Party Wall etc. Act 1996 you must serve notice before building a new wall on or astride the boundary (section 1), doing work to an existing party wall such as cutting in steel beams for a loft conversion (section 2), or excavating within 3 metres of a neighbour's building and deeper than its foundations, or within 6 metres for deeper excavations (section 6). The Act applies across England and Wales, including Dunham Massey.
One month for a new wall at the boundary or for excavation, and two months for work to an existing party wall. A notice lapses if the work has not started within 12 months.
If an adjoining owner does not reply within 14 days, a dispute is treated as having arisen. Surveyors are then appointed to agree a party wall award that sets out how and when the work can be done.
The building owner, the person doing the work, normally pays the reasonable fees of both their own surveyor and the adjoining owner's surveyor.
Not for notifiable work. You need your neighbour's written consent or an agreed award first. Starting early can lead to an injunction and delay.
No. Planning permission, Building Regulations approval and the Party Wall Act are separate. The same extension may need all three.
Read it carefully and reply in writing within 14 days. You can consent, or dissent and either share one impartial surveyor (an agreed surveyor) or appoint your own.
Usually not. The building owner normally pays the reasonable costs of the adjoining owner's surveyor.
A party wall award normally includes a schedule of condition recording your property before work starts. The building owner must make good any damage the work causes, or pay compensation.
No. The Act does not let you block work that is otherwise allowed. It controls how the work is done and protects your property while it happens.
