House Extensions in Greenwich
Create More Space with a Tailored Extension
Greenwich homes are full of potential but getting more out of them takes more than a straightforward build. Period terraces in SE10, Victorian semis near the park, Georgian townhouses close to the river each one comes with its own structural considerations, planning constraints, and party wall obligations.
At S&M Solutions, we’ve been delivering house extensions across Greenwich and SE10 for over a decade. We handle the whole process design, planning, structural engineering, and build under one contract, with one team. No passing the project between separate architects and builders. No gaps in accountability.
If you’re thinking about extending your Greenwich home, the first step is a paid site visit where we come to you, assess the property, and give you a straight view of what’s achievable and what it involves.

Why House Extensions in Greenwich Need Local Knowledge
Extending a property in Greenwich is not always straightforward. A significant number of homes in SE10 fall within or close to conservation areas like Blackheath, Greenwich Town Centre, and West Greenwich conservation areas all impose restrictions on what you can build, how it should look, and whether permitted development rights apply.
Victorian and Edwardian terraces which make up a large proportion of the housing stock in SE10 often come with removed chimney breasts, inadequate foundations for heavy rear extensions, and shared party walls with immediate neighbours. These aren’t problems that derail a project, but they need to be understood and planned for from the outset.
We know this area. We’ve worked on extensions in Greenwich, Maze Hill, Charlton, and across SE10 navigating planning applications to the London Borough of Greenwich, handling party wall agreements, and delivering work that meets both the technical requirements and the visual expectations of the area.
Frequently Asked Questions about House Extensions in Greenwich
Do I need planning permission for a house extension in Greenwich?
Not always. Many rear extensions and single-storey additions fall under permitted development rights, meaning you don't need full planning permission just a lawful development certificate. However, if your property is in a conservation area, if it's listed, or if the extension exceeds permitted development limits, a full planning application to the London Borough of Greenwich will be required. We assess this during the site visit and manage the process if an application is needed.
How long does a house extension in SE10 take?
A standard single-storey rear extension typically takes 12 to 16 weeks on site once planning is in place. Multi-storey extensions or more complex projects will take longer. Before any work starts, we'll give you a clear programme with the key stages and timelines so you know what to expect and when.
Will I need a party wall agreement?
If your extension involves work on or close to a shared wall with a neighbour which is common with terraced and semi-detached properties in Greenwich you'll likely need a party wall agreement under the Party Wall Act 1996. We'll flag this at the site visit stage and can advise on the process. It's not a barrier, just a step that needs to be managed properly.
Do you handle planning permission and building regulations?
Yes both. We prepare and submit planning applications to the London Borough of Greenwich, manage the consultation process, and handle all building control submissions and inspections through to final certificate. If your property falls within a conservation area or has listed building status, we manage those applications too.
Can you work with drawings I already have?
Yes. If you have existing architectural drawings or planning permission already in place, we can take those on and move straight to detailed design development, costing, and construction. We'll review what you have, flag anything that needs updating for buildability, and take it from there.

Once the contract is signed, we promptly begin the project, arriving fully prepared to bring your vision to life. With an online monitoring portal and biweekly meetings, we keep you updated, address any concerns, and ensure everything stays on track.
Completion & Aftercare
Upon project completion, we conduct a final walkthrough with you to ensure every detail meets your standards, followed by providing comprehensive aftercare instructions and support for any post-completion needs. Our commitment extends beyond the build, ensuring that you are delighted and well-supported even after the project is finished.
