Kelvedon Hatch, CM15
House Extensions in Kelvedon Hatch: Local Knowledge
Kelvedon Hatch is a village on the A128 between Brentwood and Ongar, surrounded by Metropolitan Green Belt countryside. It’s perhaps best known for the Kelvedon Hatch Secret Nuclear Bunker, a Cold War shelter hidden beneath a farmhouse. The village falls within Brentwood Borough, so planning and building control go through Brentwood Borough Council.
Our office in Hutton is around 5 miles from Kelvedon Hatch as the crow flies, so we are close at hand for site visits and while your project is on site. We also work regularly in nearby Doddinghurst, Ongar and Blackmore.
Planning & approvals in Kelvedon Hatch
Kelvedon Hatch is in the CM15 postcode area, and planning applications and building control for projects here are handled by Brentwood Borough Council. We work alongside you, your architect and the council from the start, so the right approvals are in place before work begins. Essex Highways looks after the roads and footways, which matters for anything that affects the public highway, such as skips, deliveries, drainage connections or a dropped kerb.
Why use a local builder?
Being based in Hutton means we know the ground conditions, councils and suppliers around Kelvedon Hatch. You deal directly with Mark or Tom Boswell, who can visit your property, talk through your plans and give you an honest quotation.
Planning & approvals
Planning Permission & Building Regulations in Kelvedon Hatch
Some extensions can be built under permitted development, while others need full planning permission — it depends on the size and position of the extension and on your property. We can talk you through what is likely to apply and work alongside your architect and the local council to get the right approvals in place before we start.
Every extension we build is inspected and signed off under building regulations, so you have the paperwork you need when it comes to selling or remortgaging.
Permitted development
Many single storey rear extensions can go ahead without a full planning application, within set size limits. We’ll help you check before work begins.
Planning & building control
Larger and two storey extensions usually need planning permission. We work with your architect and the building control inspector throughout.
