Your Local Home Extension
Specialists in Honor Oak
Honor Oak rewards extending, but two things need settling early. Drainage often crosses the rear garden, and a build-over agreement takes weeks that belong at the start of a project. The second is Honor Oak Park and Brockley conservation areas, with Article 4 controls in places, where volume limits are applied more tightly. Buildaway resolves both before design is committed. Honor Oak sits within Buildaway's established SE23 area, with extension projects completed around Honor Oak Park Station, Brenchley Gardens and Brenchley Gardens.
Across Honor Oak and SE23, Buildaway designs and builds extensions on Victorian and Edwardian terraces on sloping plots, with strong demand for loft and rear work. Regular streets include Honor Oak Park, Forest Hill Road and Devonshire Road, with One Tree Hill and Devonshire Road Nature Reserve inside the area.
With a strong reputation for quality workmanship, Buildaway delivers extension design and construction across Honor Oak and the wider SE23 area. Whether adding a single-storey rear extension or a double-storey addition, we explain the build cost and programme clearly and deliver structurally sound, well-finished results.

Frequently Asked Questions
Your questions about home extensions in Honor Oak, answered.
Do I need planning permission for an extension in Honor Oak?
Many single-storey rear extensions fall under permitted development, but that changes inside Honor Oak Park and Brockley conservation areas, with Article 4 controls in places, where allowances are materially tighter. Buildaway establishes which category your SE23 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 Honor Oak 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 Honor Oak semi-detached properties.
Will an extension affect my neighbour?
On any semi-detached or terraced Honor Oak 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.
