Frequently Asked Questions
Your questions about home extensions in Charlton, answered.
What is a build-over agreement and will I need one?
If the extension crosses a public sewer you need written consent from the water authority before building over it. It is common in Charlton because of how rear drainage runs. The application takes several weeks, so Buildaway starts it at design stage rather than letting it delay the build.
Will an extension affect my neighbour?
On any semi-detached or terraced Charlton property the Party Wall Act applies and notice must be served. Buildaway handles the notices and statutory periods, and factors them into the start date rather than discovering them mid-project.
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 Charlton 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 Charlton Village Conservation Area?
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.
