Institutional real estate investment Bouwinvest has acquired the distinctively-shaped “Hourglass” mixed-use building project within Amsterdam’s main Zuidas business district for its Dutch office and hotel funds from developer Sax Vastgoed V.O.F.
The building on the Parnassusweg has been designed by architects Dam & Partners and is due for full completion in 2020. Hourglass is being developed at a prominent location, between the Zuidas and the public transportation, the VU and the medical centre, the VUmc.

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

There will also be a 115-room extended stay hotel and a restaurant open to the public, in the building. The hotel is to be let to 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 is involved with. Again, Aronsohn provides 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 will receive a BREEAM Excellent certificate upon completion. 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.

The planned completion dates for the office section will be Q4 2019, and the hotel will be completed in Q1 2020.
