In Wassenaar, a modern residential complex is being built on the former estate of Prince Frederick of Orange-Nassau (1797-1881). Its name , 'De Frederik', is a clear reference to the Prince of Orange-Nassau. Work on designing the project started in 2015 and it is currently still under construction. The apartments are luxurious and spacious. The residential complex is characterised by the extensive gardens in the interior courtyard and the generous use of flowers and plants on the façade.
