Designed by Bjarne Mastenbroek of SeARCH and Dick van Gameren, the 89,000 sq m development was actually built on the water and provides important new space in an already dense city. IJDock covers around 89000 square meters and is a modern, high-end area with a new Palace of Justice (Public Prosecuter and the Court of Amsterdam), an office tower which includes new space for the Water Police, an apartment building with 56 apartments, a commercial strip, a 5-star hotel with 293 rooms (Room Mate hotels) and a marina with 60 slips. The underground car park comprises 500 spaces, 350 of which are public. There is also a small harbor for the Water Police. IJDock is accessible from the Westerdoksdijk via a bridge and a connecting dam.
