Expert home extensions in Romford, Cambridge & around

House extensions are not something you can create overnight. There are several important stages to be considered from the initial idea to the final realisation of the project. Here are some of the major steps you will have to go through before your house extension can come to life.


Without an appropriate design, a house extension is unlikely to be successful. It needs to include not just the aesthetic components of the project, but the technical aspects too, including materials. This is an area that we can help you with – just give us a call to discuss.

Planning permission

Current UK Building Regulations state that you need to seek planning permission for any house extension. Whilst planning permission might not be needed, depending on the size and scope of the project in question, you cannot assume, and must always apply to your local council for permission before beginning the groundwork.


As discussed elsewhere on this site, groundwork involves preparing the ground prior to beginning your home extension. This includes removing the top soil and levelling off the sub-ground level for a foundation.


This is the exciting part! Once all the permissions, design, and groundwork have been sorted – our team of expert builders will set about turning your new house extension into a reality, bringing decades of combined experience to bear on a perfect construction.
