Do I need planning permission in Dagenham?
In England a single-storey extension to a bungalow follows the normal permitted development limits (3 m or 4 m, or 6 m and 8 m through prior approval). Adding a first floor always needs planning permission.
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 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).

Extensions in and around Dagenham
Site visits are available across Dagenham (RM7, RM8, RM9, RM10, RM12, RM13). We also work in nearby Becontree (2 miles), Romford (2 miles), Hornchurch (2 miles), Barking (4 miles).
In London, space is at a premium and gardens are often short, so side returns, wraparounds and carefully planned rear extensions tend to make the most of every metre.

Site visits are free and there is no obligation. Where drawings are needed, the design stage is priced in writing before it starts.

Your questions about a bungalow extension in Dagenham
Do you cover all of Dagenham?
Yes. We cover Dagenham and the surrounding parts of Greater London. Site visits are free and there is no obligation.
How long does a bungalow extension take to build in Dagenham?
On site, typically 10 to 18 weeks once approvals are in place. Before that, allow 6–14 weeks design and approvals.
Do I need building regulations approval in Dagenham?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Can I extend a bungalow without planning permission?
In England a single-storey rear extension to a bungalow follows the same permitted development limits as a house: 3 m or 4 m, or up to 6 m or 8 m through prior approval. Adding a storey always needs planning permission.
Is it better to extend sideways or upwards?
Sideways and rearwards is usually simpler, cheaper and keeps single-level living. Upwards saves garden but means stairs, more structure and planning permission.
