Basement Extension London

Basements are often under-used spaces which may be perceived as convenient storage and become the dumping ground for the detritus of family life.
But with space at a premium and ever-rising housing costs in London, increasing numbers of owners are looking to maximize their enjoyment of this neglected area of their home.

Creating great spaces in basements

Gregory Phillips Architects have a broad range of experience refurbishing various types of existing properties, including many in London. We are skilled at recognising the potential for development of a property, whether that’s improvement and renovation, expansion, or even excavation of a new basement. We have a proven track record in delivering award-winning projects in London and throughout the Home Counties.

We have extensive knowledge and experience of basement excavation projects and are familiar with the logistics of obtaining planning consent. Our team will deal with the issues relating to structure, waterproofing, and can provide you with guidance around soil removal. Based on our expertise we can provide a design that ensures your new basement adds both space and value in a way that enhances your individual lifestyle.

A sample of the awards we have received for basement projects includes the British Property Award for Best Interior Design in the UK, winner of the Daily Telegraph Home Renovation Award for Best Extension/Remodelling, and being acclaimed in the Grand Design awards for a basement extension design.

Multiple uses for basement spaces

Among the basement projects we have carried out, we have created additional living space, as well as swimming pool areas, gym spaces, home cinemas and wine cellars. Wherever possible we look for ways to introduce natural light as that allows additional habitable rooms to be created at basement level.

Not only will your new basement increase the value of your home, but it will provide you with additional space for the benefit of your family members, to accommodate guests, or to pursue your leisure activities.

This will become a wonderful addition to the comfort and enjoyment of your home. So if you are wondering whether your home has scope for a basement why not contact us to discuss your requirements?
