A penthouse was created on the top of an interbellum appartment building in the centre of Antwerp. This volume is the office of a couple architects.They needed an extra space and came up with this solution. The penthouse stands in connection with their renovated appartment one storey below. The contrast between old and new works very nice. On the inside of the volume you have the monochromous black and white, which contrasts with the 'gold' volume on the outside. On the top terrace you have a nice overview on Antwerp and it's a great playground for kids and nice summer evenings. The appartment was put in white, exept for the wooden floor. Nevertheless the old feel of the appartment was left intact.
