Why convert a basement?

home_page_imageWith the high cost of land throughout the UK and indeed the lack of it in major city areas, converting a damp cellar or basement can be a meaningful and cost effective way of increasing your living space and enhancing its value.


In the private sector many of our clients have chosen this option rather than pay the high associated costs of moving house as their family grows allowing them to stay in their happy homes, keeping their jobs and removing the need for their children to change schools and friends.


In the commercial sector, again, many of our clients with expanding businesses have chosen this option to avoid expensive relocation and allowing them to retain their valuable staff and local clients.


In the private sector waterproofed cellars and basements can be converted into bedrooms, kitchens, bathrooms, living rooms, studies lounges, playrooms, family rooms.


In the commercial sector waterproofed cellars and basements can be converted into additional office space, additional retail sales areas, extra storage space, restaurants, bars, nightclubs or even car parks.


The list of uses is limitless and in fact such wasted space can be converted into almost anything that is needed.
