Looking for a London home extension quotation, or need more information about home and kitchen extension options? You have come to the right place!

An extension is a great way of adding extra space and value to any property, particularly in London, where space is at a premium.  There are a variety of extension types to choose from including side returns, wrap around and double storey extensions, and every extension in London we complete is tailor-made to that customer’s specific needs. Your designated Simply Extend surveyor will be able to give you a full breakdown of the services on offer and how the size and specifications of your home will determine the overall cost.
