Frequently Asked Questions
Your questions about home extensions in Crystal Palace, answered.
How much does a home extension cost in Crystal Palace?
As a guide, a home extension in Crystal Palace (SE19) runs roughly £2,500–£3,300 for a single-storey rear, £3,300–£4,500 for a larger or wrap-around scheme, and £62,500–£82,500 for double-storey work. UK build costs sit around £1,800–£3,000 per m², and London consistently lands at the upper end. Buildaway fixes your figure in a written quote after survey.
How long does a home extension take in Crystal Palace?
A single-storey extension in Crystal Palace typically takes 12 to 14 weeks on site, with double-storey nearer 16–20. Add lead-in for planning - Bromley Council runs an 8-week determination period - plus party-wall notices, which need up to 2 months in SE19 terraces. Buildaway starts the paperwork early so the build is not waiting on it.
Do I need planning permission for an extension in Crystal Palace?
Sometimes yes, sometimes no. In Crystal Palace, permitted development can cover a modest rear extension, but Bromley Council takes a close view on anything altering the street elevation, and heritage designation around Westow Hill and the Triangle removes the easy route. Buildaway checks planning, party-wall and freeholder position together.
What types of extension do you offer in Crystal Palace?
All the usual types: single-storey rear, side-return, wrap-around, double-storey and basement work. In Crystal Palace the choice is set by the plot and the planning position, not preference. Buildaway measures the SE19 site and boundary first, then advises honestly on what is achievable.
Do Buildaway handle both design and construction for Crystal Palace extensions?
Yes. Buildaway takes Crystal Palace extensions from feasibility and design through Bromley Council application, party-wall notices, Building Control, groundwork, structure and finish. One contract across every SE19 project, so the design intent and the build are the same team's responsibility.
Are your extension specialists local to Crystal Palace?
Yes, Crystal Palace is core Buildaway territory. We build extensions across SE19 regularly and understand both the buildings and the Bromley Council policies that govern them.
