Recent legislation has already seen many office spaces converted to residential, having obtained the necessary planning consent. At the moment it is fairly easy to convert the use of space from B1(a) (offices) to C3 (residential). Many landlords have proceeded to change the use of their properties in this way, as the buildings can be worth three times the value when classified and used as C3. Areas such as Mayfair, Knightsbridge and Covent Garden have been hit the hardest, and we now see a significant lack of supply in these hubs.
