Frequently Asked Questions
Your questions about home extensions in Elmers End, answered.
Can I stay in the house during the build?
Usually yes for a single-storey rear extension, since the existing structure stays sealed until late in the programme. Buildaway phases the Elmers End work so the opening-up happens over the shortest practical period.
How long does a rear extension take to build?
A single-storey rear extension is generally ten to fourteen weeks on site once foundations start, depending on glazing lead times. Double-storey work runs longer. Buildaway separates the design and consent period from the build period on the programme so expectations are realistic.
Can you extend within Beckenham conservation boundaries?
Sometimes, but the tests are stricter and additions are assessed against the original dwelling rather than its current size. Buildaway will tell you honestly at survey stage whether a scheme is likely to succeed before you spend money on drawings.
Do I need planning permission for an extension in Elmers End?
Many single-storey rear extensions fall under permitted development, but that changes inside Beckenham conservation boundaries and standard Bromley permitted development limits, where allowances are materially tighter. Buildaway establishes which category your BR3 property falls into before drawing anything.
Do you handle drawings and building control?
Yes. Buildaway coordinates structural calculations, the building control application and inspections, and manages the party wall process where a neighbouring wall is affected, which is frequent on Elmers End semi-detached properties.
