Petts Wood
Petts Wood is known for its distinctive 1930s suburban character, with detached and
semi-detached houses set along tree-lined avenues radiating from the village high street and
station. Many properties here were built with generous plots, wide frontages, and decent-sized
gardens conditions that give homeowners more room to extend than is typical in denser parts of
London. Bromley Council generally takes a reasonable approach to residential extensions in BR5,
though parts of Petts Wood fall within conservation area boundaries where stricter design
guidance applies, particularly around the original Petts Wood Estate streets near the station.
Buildaway's team checks each property's specific designation before any design work
starts.
The typical Petts Wood semi or detached house has good potential for a rear kitchen extension
that opens the ground floor onto the garden, often paired with a side infill where the gap
between properties allows it. Detached houses in particular can sometimes accommodate
wrap-around extensions that combine both rear and side space into a single larger room a popular
option for families wanting an open-plan kitchen, dining, and living area without losing too
much garden. Buildaway's architects assess the existing layout and garden orientation to work
out which configuration gives the best result for the space and budget available.
Foundations and drainage on Petts Wood's older 1930s properties vary depending on when and how
each house was originally built, and this affects how a new extension needs to be tied into the
existing structure. Some properties also sit on sloping plots, which can influence floor levels
and require additional groundworks for a rear extension to sit correctly against the existing
house. Buildaway's surveys cover all of this before a quote is finalised, so the figure you
receive reflects the realities of your specific property. Whether it's a rear extension on a
semi near Petts Wood station or a wrap-around build on a detached house toward Hawkwood Lane,
Buildaway delivers extensions that are properly designed and built to last.

What Our Petts Wood Clients Say
Real reviews from our satisfied customers.
"We wanted a wrap-around extension on our detached house near Hawkwood Lane and after meeting with several builders, I decided to go with Buildaway. Cormac and his team handled the structural steels and the layout changes flawlessly. The new open-plan space has transformed our home."
Arthur Pendelton
Hawkwood Lane, Petts Wood BR5
"It was an absolute pleasure working with Cormac and the Buildaway team on our 1930s semi rear extension on Towncourt Lane. Being near the conservation area, we were worried about planning permissions, but Buildaway managed the design submission smoothly. Beautiful finish and matching brickwork."
Eleanor Hayes
Towncourt Lane, Petts Wood BR5
"Buildaway recently completed a side return and kitchen extension on our property near Queensway. The design was brilliant and they recommended bringing in roof glazing to maximise light. The team was extremely professional throughout."
Marcus Sterling

"The double-storey extension on our home near Crofton Lane is fantastic. The extra space has given us a new main suite upstairs and a beautiful utility room downstairs. The pricing was completely transparent and matches exactly what we were quoted."

Frequently Asked Questions
Your questions about home extensions in Petts Wood, answered.
How much does a home extension cost in Petts Wood?
In Petts Wood BR5, single-storey rear extensions typically cost £40,000 to £58,000, while double-storey additions range from £78,000 to £100,000. Petts Wood sits in Bromley, where build costs are generally lower than in inner London boroughs. Buildaway provides a fully itemised quote after a free survey so you have a clear figure before any work begins.
Do I need planning permission for a home extension in Petts Wood?
Many properties in Petts Wood can extend under permitted development, particularly the detached and semi-detached houses typical of the area's 1930s suburbs. However, parts of Petts Wood fall within designated conservation areas where additional design controls apply. Buildaway checks your property's status first and handles whichever application route is required with Bromley Council.
What types of home extensions suit Petts Wood properties?
Petts Wood's housing stock is largely 1930s suburban semis and detached houses with generous gardens, making rear extensions, side infills, and double-storey additions all viable options. Many properties also have room for wrap-around extensions that combine rear and side space into one larger area. Buildaway surveys the plot and structure before recommending what suits your home and budget.
How long does a home extension take in Petts Wood?
Single-storey extensions typically take 12–14 weeks on site, while double-storey projects run 16–20 weeks. If a planning application is required, add 8–10 weeks for Bromley Council's determination period. We set out a full programme covering both planning and construction at the initial consultation, so the timeline is clear from the outset.
Will I need a party wall agreement for my Petts Wood extension?
It depends on the property many Petts Wood homes are detached or have wide side gaps, which can avoid party wall requirements altogether. Semi-detached properties extending to the side or rear will usually need one. Buildaway assesses this during the site survey and manages the full notice process where it applies, as part of the project.
Do you handle both design and construction for Petts Wood extensions?
Yes architects, structural engineers, and all trades work through Buildaway directly. There's no handoff between a separate designer and a separate builder. One team manages everything from initial drawings and planning through to Building Control sign-off and final finishes.
Is a home extension in Petts Wood a good investment?
Petts Wood remains popular with families thanks to its good schools, mainline station, and village-style high street, all of which support strong demand for larger homes. A well-built rear or double-storey extension on a typical BR5 semi or detached house generally adds more value than the build cost, particularly where it creates extra bedrooms or a larger kitchen-diner.
