Maisonettes can create Party Wall questions that are less obvious than those affecting conventional terraced houses.
Because one home may sit partly above, below or alongside another, both horizontal and vertical party structures can be involved.
What is a party structure?
Floors and ceilings separating different owners can constitute party structures under the Party Wall etc. Act 1996.
Our Section 20 definitions guide explains the terminology.
Typical maisonette alterations
Party Wall considerations may arise where works include:
- removing structural walls;
- altering separating floors;
- cutting structural beams into shared walls;
- forming new stair openings;
- relocating staircases; or
- undertaking substantial roof alterations.
The fact that all works appear to take place “inside your flat” does not automatically mean they cannot affect a party structure.
Several adjoining owners
Depending on the arrangement, structural works could potentially affect owners above, below or alongside the property.
The title structure should therefore be understood before notices are prepared.
Freeholder consent
Most maisonettes are leasehold.
The lease may contain restrictions on structural alterations and may require a formal licence to alter.
Party Wall rights do not replace those contractual requirements.
Get drawings before serving notices
Accurate architectural and structural information makes it much easier to determine precisely which elements of the Act are relevant.
Our guide to Party Wall Notice drawings explains the importance of clear technical information.
Simple Survey can advise
If you are altering a maisonette, Simple Survey can review the project and identify any Party Wall requirements.
