Mayfair’s Georgian townhouses are mostly apartments now. Shops often fill the ground floor.

A lateral flat joins two buildings side by side. That means a new opening through the party wall.

Cutting into a party wall needs two months’ notice. Every owner of that wall must receive it.

Below you, the shop’s owner may count as an adjoining owner. So may the freeholder above.

Behind the main streets sit mews houses. Their walls are shared closely, so most structural work is notifiable.

What the council allows in Mayfair.

Council: City of Westminster, for planning. The Mayfair Neighbourhood Plan was made in December 2019.
Openings: Cutting into a party wall for a lateral flat takes two months’ notice.
Owners: Freeholders and long leaseholders of the wall or floor each count as owners.
Floors: A floor dividing your flat from a shop below is a party structure.
The lease: An award does not replace the landlord’s licence. Both are needed.
