Service overview
What this service covers.
Owners converting loft space in terraced, semi-detached or attached buildings.
Loft conversions commonly involve cutting steel bearings into a party wall, raising or exposing shared walls and altering a party structure. The final structural design—not the presence of a dormer by itself—decides which work may be notifiable.
When this service may be relevant
- Steel beams or padstones will be supported by a party wall.
- The party wall will be raised or weathered at roof level.
- Works affect a floor or wall separating differently owned flats.
Who this is for
Owners converting loft space in terraced, semi-detached or attached buildings.
How the instruction is approached
A clear route, matched to the facts.
The Act’s requirements and any boundary procedure depend on the actual documents, ownership and site relationships. These are the usual working stages.
- 01
Check the facts
Review the drawings, ownership interests, neighbouring structures and intended start date before deciding which notice route is relevant.
- 02
Prepare the documents
Describe the work accurately, attach the information required for that notice type and identify every owner who may need to be notified.
- 03
Serve and record
Serve the notice by an authorised method, retain evidence of service and track the statutory response and notice periods.
Questions about Loft Conversions
Useful context before you instruct.
General information only. Advice on a particular property requires the relevant documents and facts.
01Is a dormer automatically notifiable?
No. The relevant issue is the work to the party wall or structure and the design details. A dormer wholly clear of shared structures may not itself engage the Act.
02Is planning approval enough?
No. Party Wall procedure is separate from planning permission and building regulations.
