Covering Norwich
Across NR1, NR2, NR3, NR4, NR6, NR7, we can visit, measure and advise. The same team covers Wymondham (9 miles), North Walsham (14 miles), Dereham (16 miles), Great Yarmouth (18 miles), all within easy reach.
Lowestoft, in Suffolk, is roughly 22 miles from Norwich and also on our list. The East of England mixes market-town terraces, inter-war semis and modern estates. Clay soils are common in parts of the region, which can affect foundation design.
What we take care of
- Planning check against the porch limits
- Design to suit the house style
- Tiled, slate or flat roof
- Brick, render or oak frame walls
Proportion matters on a porch more than on any other extension, because it is at the front. We match the roof pitch and brick and keep the front door in proportion with the house windows.
Do I need planning permission in Norwich?
In England a porch is usually permitted development if its ground floor area is no more than 3 m² measured externally, no part is over 3 m high, and no part is within 2 m of a boundary next to a road.
Homes in conservation areas, national parks, National Landscapes (formerly AONBs), the Broads and World Heritage Sites have tighter rules, so we always check the property's status and planning history before design starts.
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.
Building regulations approval is separate from planning. In England you can use the council's building control team or a registered building control approver; a full plans application gets the drawings checked before work starts, and the inspector signs the work off with a completion certificate.
Applications are decided by the local planning authority (your district, borough or unitary council).
