Local to North Walsham
Our survey diary covers North Walsham, including NR28. We also work in nearby Cromer (8 miles), Norwich (14 miles), Great Yarmouth (20 miles), Wymondham (21 miles).
Just over the Suffolk border, Lowestoft is about 28 miles away. Across the East of England many houses sit on generous plots, and single-storey and wraparound extensions are a natural fit.
Who a wraparound extension suits
- Families who want kitchen, dining and living in one space
- Terraced houses that want the largest ground floor possible
- Semi-detached houses with a side passage
The corner is where wraparounds succeed or fail. We usually use a single steel goalpost or a corner post hidden in a pier, and set the glazing so the new room reads as one space rather than two boxes.
Planning and approvals in North Walsham
In England a wraparound extension is assessed as both a side and a rear extension, and the combination usually falls outside permitted development, so most need a householder planning application (£548 from 1 April 2026).
The planning position for a specific North Walsham address depends on its history and any designations, which is why we check it at the first visit.
Building over or within 3 m of a public sewer needs the water company's consent, usually through a build-over agreement, before the foundations go in.
If the work involves a shared wall, building on the boundary, or digging foundations within 3 m (sometimes 6 m) of a neighbour's building, the Party Wall etc. Act 1996 applies and notice must be served before work starts: two months for work to a party wall, one month for new walls on the boundary and for excavations.
Applications are decided by the local planning authority (your district, borough or unitary council).

Common questions in North Walsham
Do you cover all of North Walsham?
Yes. We cover North Walsham and the surrounding parts of Norfolk. Site visits are free and there is no obligation.
Do I need building regulations approval in North Walsham?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Will my neighbours in North Walsham be involved?
If a planning application or prior approval is needed, the council notifies neighbours. If the work is on or near a shared boundary, party wall notices may also be needed.
Is a wraparound better than a side return alone?
It adds far more space, but costs more and needs planning permission more often. Our comparison guide sets the two side by side.
Will I need to move a drain?
Often. Side returns frequently contain a manhole or a shared drain. Building near or over a public sewer needs the water company’s consent in England and Wales, which we arrange.
