Removing an External Conservatory Built Against a Party Wall
It depends on how the conservatory is attached. Demolishing one that simply abuts a wall may not need a notice. If the removal cuts into the party wall, removes fixings set into it, or disturbs shared foundations, the Party Wall etc. Act 1996 may apply.
Look at how it was built
Conservatories are often fixed to the house wall with ties, flashings, and cut-in cills. If the conservatory abuts a party wall or was built up against a boundary wall, some of those fixings may be in shared masonry. Removal can leave holes to fill and surfaces to repair.
When notice is likely
- Cutting out lead flashings or joists set into the party wall.
- Demolishing a wall that forms part of the party structure.
- Excavating to remove foundations close to a neighbouring building.
- Rebuilding or making good the wall where the structure was attached.
When it may not be needed
If the frame is free-standing, fixed only to your own wall, and comes away without touching the shared wall or its foundations, the Act may not be engaged. Be honest about what is in the ground and in the masonry before deciding.
Timing and process
Where notice is needed, allow at least two months for work to an existing party wall, or one month for excavation. The neighbour has 14 days to respond. If surveyors are appointed, the award will deal with making good and protecting the neighbour's side.
Waste, dust and access
Removal is messy. Agree working hours and how you will access the site without crossing your neighbour's land unless they allow it. Photograph the wall before you start.
If the conservatory sits on foundations shared with a boundary wall, ask a builder or engineer to expose them carefully first. Finding out what is below ground before you start avoids surprises that would otherwise need an urgent notice or a stop in work.
Frequently asked questions
Was the conservatory built with a notice originally?
Check your papers. If it was not, that does not change what is required now for removal.
Who repairs damage to the neighbour's wall?
The building owner must make good damage caused by the work or pay for it.
Do I need building regulations approval?
Demolition may need separate notices to the local authority. Ask building control.
