Planning and approvals in Truro
In England a single-storey rear extension can usually go up to 3 m beyond the original rear wall of a semi-detached or terraced house, or 4 m on a detached house, without a planning application, provided it is no more than 4 m high, keeps eaves to 3 m within 2 m of a boundary and, with other buildings, covers no more than half the land around the original house. The larger home extension prior approval scheme raises those depths to 6 m and 8 m, with neighbours notified and a 42-day decision.
In a conservation area, national park, National Landscape, the Broads or a World Heritage Site the permitted development limits are tighter (no side or two-storey extensions without an application). Listed homes need listed building consent, and if permitted development rights have been removed, any extension needs an application.
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.
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.
Applications are decided by the local planning authority (your district, borough or unitary council).
What is included
- Roof lantern or rooflights positioned over the work zones

Extensions in and around Truro
Our survey diary covers Truro, including TR1. Neighbouring towns we cover include Falmouth (8 miles), Redruth (8 miles), Newquay (10 miles), Camborne (11 miles).
Plymouth, in Devon, is roughly 41 miles from Truro and also on our list. South West homes range from terraced streets in the cities to stone cottages and bungalows in the countryside, and conservation areas are common in historic centres.
From first visit to completion
Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.
Free site visit
We visit your Truro home, measure up, talk through what you want and check the planning position.
Design and approvals
Once the layout is agreed, we deal with the council: planning permission or written confirmation that none is needed, plus building control.
Fixed written price
We confirm the build price in writing, based on the approved drawings and the finishes you have chosen.
Build and sign-off
Work is carried out to the agreed programme, inspected by building control and signed off at the end.
Common questions in Truro
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Truro, and the guide-price tool gives a range for your own size. After the survey you get a written price before anything is agreed.
Do you cover all of Truro?
Yes. We cover Truro and the surrounding parts of Cornwall. Site visits are free and there is no obligation.
Do I need building regulations approval in Truro?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
How much does a kitchen extension cost?
For the extension itself our guide range is about £1,840 to £3,570 per m² including VAT. A standard 20 m² kitchen extension is typically around £42,500 to £54,500 in Truro, plus the kitchen itself, which commonly adds £9,000 to £20,000 for a mid-range design.
Where should the island go?
Usually under the brightest part of the roof and away from the main walkway to the garden. We test two or three layouts on the plan before deciding.
