A four-storey vertical light well has dramatically transformed this traditional Victorian property into an exceptional light and modern family home with a three-storey feature bookcase rising through the house. Appearing to cut its way through the building, the light well slots between the original rear elevation and the main body of the house, creating interconnected spaces between the original house and a new extension to the rear, where an impressive double-height glass extension encapsulates the new family living areas and the first floor above.
