Covering Seaford
Seaford sits 11 miles east of Brighton, with Rottingdean 8 miles to the west and Eastbourne 8 miles to the east.
Homes in the South East
Housing across the South East mixes inter-war semis, post-war estates and older cottages in villages and market towns, so rear and side extensions, hip-to-gable lofts and garage conversions all come up regularly.
What goes into a mansard loft conversion?
A mansard loft conversion replaces one or both slopes of a roof with a near-vertical wall, typically at 70 degrees, with small dormer windows set into it. It creates almost a full extra storey and is common on terraced houses in towns and cities, particularly in London.
- Roof removal and new mansard frame
- Slate cladding and lead-clad dormers
- En-suite, electrics and fire safety

Planning and building rules in Seaford
In England we deal with the council’s planning team for permission or a lawful development certificate, with building control (the council or a registered building control approver) for inspections, and with neighbours under the Party Wall etc. Act 1996 where it applies.
Mansard conversions change the shape of the roof significantly, so they usually need planning permission in England.
What can change the price or programme?
- A mansard nearly always involves party walls on both sides of a terrace.
- Council design guides often require natural slate and lead.
From first call to completion
- Tell us about the project. Call, use the guide price tool or send the form with a few photos and a postcode.
- We visit and measure. A surveyor checks the house, the boundaries and the ground, and discusses what is realistic.
- Price and paperwork. The design is priced line by line, and we submit the planning and building control applications.
- Construction and completion. One site lead co-ordinates every trade through to the building control certificate.
What people ask before starting
Does a mansard need planning permission?
Almost always, because it changes the roof profile.
Will I need party wall agreements?
Very likely, as the work affects the walls shared with both neighbours on a terrace.
