The Maastoren (Dutch for Meuse Tower) is with its height of 165 metres (541 feet) the second tallest building in the Netherlands.

[6] When the Dutch branch of Deloitte wanted a new headquarters, it chose for the current location of the Maastoren.

[9] Dam & Partners Architecten designed the Maastoren with Odile Decq Benoit Cornette.

Also, engineering firm Zonneveld and the company Techniplan Adviseurs were involved in the developing process.

[5] The municipality of Rotterdam agreed with the construction of the Maastoren, but in April 2006 the council called for a debate on the subject.

[10] At the end of May, alderman Hamit Karakus said to the council that the Maastoren would be built and that the municipality would listen to the objections.

[11][15] The process of making the site ready for construction started at the end of July 2006, but the preparations were shut down two weeks later on 3 September.

[22] To celebrate this occasion, alderman Hamit Karakus and CEO of OVG Coen van Oostram abseiled down the building to the 31st floor two days later.

[7] The developer, OVG, sold the Maastoren to the German company SEB Asset Management for €159.5 million the same year.

OVG, the developer, received a plaque from the Council on Tall Buildings and Urban Habitat.

The plaque states the Maastoren has a height of 164.75 metres (541 feet), and is the tallest building in the Netherlands.

[26] In December 2014, the American real estate company NorthStar bought a portfolio, that consisted of eleven office buildings including the Maastoren, from SEB Asset Management.

[25] In 2018, the Maastoren was acquired by an investment consortium led by FOM Real Estate from Heidelberg, Germany.

[7] The aluminium panels cover slightly more than the upper half of the Maastoren, and they become lighter as the building rises.

[35] The dark grey dimension stones at the bottom are meant to resemble the basalt wharf.

[5] Situated above the underground parking garage, the ground floor houses the main entrance, above which a glass canopy is located to decrease the effect of the wind.

[8] The office floors of Deloitte and AKD start above the parking garage, and continue to the top of the Maastoren.

These glass walls extend beyond the roof to create the illusion that the Maastoren fades into the air.

The competitors start at the bottom of the office building, and have to reach the top of the Maastoren by using the stairs only.

[2][42] De Vernufteling was awarded to Techniplan Adviseurs because of the heating and cooling system of the building, that uses seasonal thermal energy storage.

[35] The FGH Vastgoedprijs was awarded to the developer OVG by Aleid Wolfsen, back then mayor of Utrecht, on 8 November 2010.
