Neighbour rights when installing a dormer

From a dormer window you may not have direct view onto a neighbouring plot within 2 metres of the boundary. On end-of-terrace houses this can cause issues.

Solutions: frosted glass, fixed pane without open view (no tilt window), or explicit written neighbour consent. Consent is personal; if the neighbour sells, you need new consent from the new owner.

The permit test reviews building rules and aesthetics, not civil neighbour rights. A granted permit doesn't mean you're legally safe versus neighbours.

Tell neighbours in advance — communication prevents 90% of disputes. A drawing and planning by email to neighbours, inviting reaction within 2 weeks, is cheap insurance against later objection procedures.

During installation crane work, dust or vibration can damage neighbour properties. Your contractor should carry CAR insurance (Construction All-Risk).

Ask for proof before start. Without cover, you're personally liable as principal. Standard €500,000-€1,000,000 property damage cover suffices for regular dormers; for urban crane work request €2,000,000.

Some plots carry easements or chain clauses limiting extensions — mainly in listed areas and HOA (VvE) apartments. Check your deed and HOA split deed for restrictions.

In HOA apartments roof changes almost always require 2/3 member majority. Plan 3-6 months for the decision process; schedule early and deliver drawings ahead of the general meeting.
