Frequently Asked Questions
Your questions about home extensions in Grove Park, answered.
Can you extend within Lewisham permitted development limits?
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 Grove Park?
Many single-storey rear extensions fall under permitted development, but that changes inside Lewisham permitted development limits and Chinbrook conservation boundaries, where allowances are materially tighter. Buildaway establishes which category your SE12 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 Grove Park semi-detached properties.
What usually drives the cost up?
Groundworks and glazing. Poor ground conditions mean deeper foundations, and large glazed openings need steel. Both are established at survey in SE12, so Buildaway prices them properly rather than provisionally.
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 Grove Park 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.
