Planning and approvals in South Ockendon
In England a two-storey rear extension is permitted development only if it projects no more than 3 m from the original rear wall, sits at least 7 m from the rear boundary, matches the roof pitch and uses obscure, non-opening side windows upstairs. Most two-storey extensions therefore go through a householder planning application, which costs £548 from 1 April 2026 and normally takes about 8 weeks.
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).
Covering South Ockendon
Across RM15, RM20, we can visit, measure and advise. Neighbouring towns we cover include Grays (3 miles), Stanford-le-Hope (7 miles), Brentwood (8 miles), Basildon (9 miles).
Across the East of England many houses sit on generous plots, and single-storey and wraparound extensions are a natural fit.
Included in a typical project
- En-suite drainage and ventilation design
- Fire safety: escape windows and smoke alarms to building regulations
- Planning drawings and application
- Structure, roof, insulation and finish
- Layout options: two-storey, over-garage or ground floor
New bedrooms on an upper floor need an escape window or a protected route to the outside under the building regulations. We design the window sizes and stair route to meet that from the outset.

Questions people ask about bedroom extensions
Can I see a price before committing to anything?
Yes. The guide prices on this page are adjusted for South Ockendon, 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 South Ockendon?
Yes. We cover South Ockendon and the surrounding parts of Essex. Site visits are free and there is no obligation.
Do I need building regulations approval in South Ockendon?
Yes. Almost every extension needs it, whatever the planning route. We prepare the drawings and book the inspections.
Can I add a ground-floor bedroom for a relative?
Yes. A ground-floor bedroom with an accessible shower room is a common request. If it will be lived in as a self-contained home, planning treats it differently, so tell us how it will be used.
Will a new bedroom need planning permission?
Upstairs additions usually do. Ground-floor rooms may fall within permitted development, depending on size and position.
