Do you need planning permission for a wraparound extension in Burgess Hill?
Here is how the rules work for a wraparound extension in England. In England a wraparound extension combines side and rear elements, which normally takes it outside permitted development, so a householder planning application is made.
Building regulations approval comes from the council’s building control service or a registered building control approver. The work is inspected at key stages, such as foundations, drainage and insulation, and a completion certificate is issued at the end.
At the survey we check your house’s planning history and any restrictions, and tell you which route applies.
What we handle
From survey to sign-off, the job normally involves:
- Structural engineer’s design for steels and supports
- Underfloor heating option, electrics and plastering
- Party wall notices and surveyor liaison
- Building control completion
- Walls, roof and glazing
- Removal of internal and external walls
How long does it take?
Expect 12 to 18 weeks on site. Allow time beforehand for drawings and approvals, usually 3 to 4 months.
