Local to Poole
Our survey diary covers Poole, including BH12, BH13, BH14, BH15, BH16, BH17. Nearby, we also take on projects in Bournemouth (5 miles), Wimborne Minster (7 miles), Swanage (7 miles), Ferndown (8 miles).
New Milton, in Hampshire, is roughly 14 miles from Poole 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.
Planning and approvals in Poole
In England the main routes are permitted development (ideally confirmed with a lawful development certificate, £274), larger home extension prior approval (£249, 42 days) and a householder planning application (£548, normally 8 weeks), with council fees as set from 1 April 2026.
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.
Applications are decided by the local planning authority (your district, borough or unitary council).

Questions answered
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for Poole, 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 Poole?
Yes. We cover Poole and the surrounding parts of Dorset. Site visits are free and there is no obligation.
How long does this take for a Poole home?
2–6 weeks for drawings, depending on the council and the complexity of the project.
Do I need an architect?
Not necessarily. For most extensions an experienced designer or architectural technologist is enough. For listed buildings or complex sites an architect’s input can help.
How much do extension plans cost?
Our design packs range from about £1,200 to £5,650 including VAT, from planning drawings only to a full pack with building regulations drawings, structural calculations and 3D views. Council fees are separate.
