Frequently Asked Questions
Your questions about home extensions in Woolwich, answered.
Do I need planning permission for an extension in Woolwich?
Many single-storey rear extensions fall under permitted development, but that changes inside Royal Arsenal and Woolwich Common conservation areas with listed building constraints, where allowances are materially tighter. Buildaway establishes which category your SE18 property falls into before drawing anything.
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 Woolwich 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.
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.
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 Woolwich semi-detached properties.
Will an extension affect my neighbour?
On any semi-detached or terraced Woolwich 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.
