How much will a home extension in London cost?

That’s like asking how long is a piece of string? Still, we understand that it’s important to know even an approximate cost before deciding whether you are financially able to undertake a home extension project.  

We did some digging around and found this handy Extension Cost Calculator on the Homebuilding and Renovation website. All you need to do is enter some details about your property.  

BIG DISCLAIMER! The costing you receive from this cost calculator is only an approximate indicator. It is by no means set in stone and has the potential to increase or decrease based on your specific requirements. Its only purpose is to give you a general idea.  


If you’d like some more detailed guidance and costs on your home extension project, give us a call on 02081917595. Or better still, book a FREE consultation with us and we’ll visit your property, discuss your ideas and share some of our recommendations with no obligation.
