The Hourglass Building consists of 35.000m2 GFA of multi-tenant offices, of which the main tenant Loyens & Loeff occupies 15,500m2 GFA, as well as 700m2 GFA of retail and catering and 145 parking spaces.

There is also a 115-room extended stay hotel and a restaurant open to the public, in the building. The hotel is by international operator the PREM Group, which will cater for the office tenants of the Hourglass, and rising demand from the many Dutch and international companies in the Zuidas generally, with its Premier Suites living environment concept.

In addition to the developments of Gershwin Brothers and NoMA House, Hourglass is the third project at the Zuidas that Aronsohn Management was involved with. Again, Aronsohn provided project management on behalf of SAX Real Estate V.O.F. (an initiative of Maarsen Group and Brouwershoff). Since the beginning of 2016 Aronsohn Management has been involved with the Hourglass project and carried out the tender procedures on the basis of the preliminary design. The project has been procured using the phase A-B method as developed by Aronsohn (phase A1, A2 and B).

Hourglass has been completed in May 2020.

Upon completion Hourglass received a BREEAM Excellent certificate. This certificate not only evaluates energy efficiency, but also elements such as flexibility, adaptability and user comfort. Hourglass being a smart building, controlling the lighting and temperature of the building with a smartphone are possibilities, as well as occupation registration and climate control etc.
