01Extending in Portishead
The houses here, and how they extend.
Portishead has grown in layers, and the roof you have depends on which layer your house came from. The older streets up towards Nore Road and Down Road are largely 1930s semis and detached houses with cut roofs — rafters and purlins, and usable space between them.
The marina and the estates built around it are much newer, and almost all of them are trussed-rafter roofs. Those are designed to be efficient rather than convertible, so the loft is filled with bracing and the conversion means altering that structure properly.
Plots on the newer estates tend to be tighter, so a rear extension is usually about using the full width well, with a steel over a wide opening into the existing house rather than a small door into a separate room.
02Planning & approvals
What your project is likely to need.
North Somerset Council is the planning authority. Many houses here can extend or convert under permitted development, but estates built with planning conditions or covenants sometimes cannot — it is worth checking the title and the original consent early.
Building Regulations approval is needed for every loft conversion and extension. Planning permission is not always — and where a shared wall is involved, the Party Wall Act usually is. We will go through all three with you before anything is priced.
