Structural floors can deteriorate or require replacement during major refurbishment.
In houses this may be an entirely internal issue, but in flats the floor can form the physical separation between different properties.
That can make it a party structure.
Floors can fall within the Party Wall Act
The Party Wall etc. Act 1996 is not limited to masonry walls.
A floor separating different ownerships can be a party structure.
Our Party Wall definitions guide explains how shared structures are treated.
When might a floor be replaced?
Structural floor replacement may arise because of:
- timber decay;
- fire damage;
- significant water damage;
- structural inadequacy;
- major refurbishment; or
- a change to the building layout.
Minor flooring works are different
Replacing carpets, laminate, tiles or other finishes does not automatically amount to alteration of the party structure.
The key distinction is whether the structural floor itself is being altered.
Noise and acoustic performance
Structural floor replacement within flats may also affect acoustic performance.
Building Regulations, lease requirements and landlord approvals may therefore need to be considered independently of the Party Wall Act.
Structural information
For significant works, drawings should identify which parts of the floor are being removed, replaced or strengthened.
If beams or supports are being inserted into shared walls, Section 2 may also apply.
Read our Section 2 guide for more information.
