Terraced house rear extension in Greenwich
Terraced house rear extension in Greenwich: rear and side return extensions for terraces, with access through the house and two neighbours. We measure the house, show you what the rules allow, price it in writing and build it.
We cover Greenwich (SE3, SE7, SE10 and SE12) as part of our Greater London work. In Greenwich we plan the delivery route through the house and the skip licence before anything else.

Do you need planning permission for a terraced house rear extension in Greenwich?
Here is how the rules in England apply to a terraced house rear extension in Greenwich.
Under England's householder permitted development rules you can usually add 3 metres at the back of an attached house, or 4 metres on a detached house, without a planning application, as long as the extension stays under 4 metres high and its eaves stay under 3 metres where it is within 2 metres of a boundary.
The Party Wall etc. Act 1996 applies in England: you serve notice two months before work to a shared wall, and one month before digging foundations within 3 metres (or 6 metres for deeper foundations) of a neighbour's building. Neighbours can agree in writing; if they dissent, surveyors agree an award.
Conservation areas, National Parks, National Landscapes and the Broads restrict permitted development, and listed buildings always need listed building consent. Before any drawing we look up the property's history with the council, because earlier extensions and removed rights change the answer.
What are homes in Greenwich like to extend?
Period terraces in Greenwich sit alongside flats, and the difference matters: houses usually keep permitted development rights, while flats and maisonettes need planning permission for any rear extension.

FAQ
Terraced house rear extension questions in Greenwich
Do I need planning permission for a rear extension in Greenwich?
Often not for a single-storey rear extension of up to 3 metres (4 metres on a detached house) under permitted development, or up to 6 or 8 metres with prior approval, unless the house is in a conservation area or its rights have been removed.
Will I need a structural engineer?
Yes for the beam over the new opening and usually the foundations; we arrange them and their calculations go to building control.
Do both neighbours need party wall notices?
Usually yes in England and Wales, because the extension often sits on or near both boundaries.
Who will build my extension?
Vetted building teams working under contract to us. Your contract is with S&K Property Investments and Improvement Ltd for the design and the build.
Is the site visit in Greenwich free?
Yes. We visit, measure up and talk through the options with no cost and no obligation.
Do you handle building control in Greenwich?
