De Cube on the Kalfjeslaan in Delft is no ordinary building. Architect Jan Brouwer designed it in 1987 as an office building, with a façade made up entirely of prefabricated elements.
In 2018, Kasteel BV converted part of the building into modern apartments. Businesses still occupy the rest, so people both live and work here. The A13 motorway, the station and the TU Delft Campus are all within easy reach.
The apartments are connected to our fiber network, and the businesses in De Cube can come to us too. Do you live or work here? Enter your address above and see straight away what's possible.
