About Het Strijkijzer

Het Strijkijzer is a fully pre-cast residential tower with an L-shaped plan. Sited on a triangular site of only 37 meters by 34 meters (121 by 111 feet) at one of The Hague’s busiest intersections, the building takes cues from The Flatiron Building in New York City (1902) in its form. The building contains luxury apartments and studios intended to provide an affordable housing option to young adults and students. There are also many public features on the first three levels, and a Grand Cafe surrounded by an outdoor gallery on the top floor with separate elevator access.

With the small site completely occupied by the building, there was no room for a construction staging area, and as such innovative construction methods were developed. Two different companies prefabricated the concrete floor and wall pieces. The delivery trucks would have to meet on the highway and ensure they were driving in the correct order so that when they arrived at the site, the parts could be taken from the trucks and installed on the building immediately. This led to an incredible construction speed of two floors a week.
