Why a basement conversion ?:



Why convert your basement/cellar?

There is an ever increasing demand to create more space within our homes.



If you want to extend outwards, in a majority of circumstances you will need planning permission. Loft conversions are excellent for extra bedrooms and bathrooms, but imagine a kitchen or laundry 3 floors up? The other downside of loft conversions is the amount of usable headroom you can create.


When converting your basement, invariably all of the floor space is usable, thus making a basement conversion better value for money per square metre.
