Rising 40 meters above the surrounding waters of the IJmeer, Sluishuis is part of IJburg, a residential area made up of four man-made islands.

Described as a “modern, sustainable way of life on and around the water” and designed for a variety of income levels and age groups, the Sluishuis building includes 442 owner-occupied and rental apartments, 234 parking spaces, underground parking, 34 lots of barges and 54 berths. for pleasure boats.

After being awarded the contract by the Municipality of Amsterdam in 2016, Besix Red worked alongside Rotterdam-based developers Vorm Bouw to build the structure, appointing architects Bjarke Ingels Group (BIG) of Denmark and Dutch Barcode for the project .

According to Besix, who recently received approval for the design and construction of a new 30,000 seater stadium in Christchurch, New Zealandthe sustainability of the building was a key consideration for the project.

The building, which connects directly to the city center via a bridge and also includes 1000m² of catering facilities, 112m² of retail space and a shared roof garden, has an energy performance coefficient (EPC) of 0 .00 and generates more energy than it consumes.

A heat and cold storage system (CHS) installed in the ground, coupled with high-performance insulation and heat recovery systems help to minimize heating needs.

A total of 2,200 m² of solar panels, located on their own nearby floating island, provide energy to the building – a feature that Besix Red says “fully offsets” the energy needs of heating, heat pumps, ventilation and LED lighting of the structure.

Gabriel Uzgen, CEO of Besix Red, said: “Beyond the ambitious architecture designed by BIG and Barcode Architects, Besix Red was won over by the ESG commitment of the project, which is fully in line with our values.

“This formula has proven itself and has won over the investor, BouwInvest, as well as individual buyers looking for a unique life experience and an ESG investment.

Jan-Bert Vroege, District Administrator of the Municipality of Amsterdam, added: “With the completion of Sluishuis, IJburg will have a new iconic entrance. It gives a new face to a district that is still in full development and will continue to grow in the years to come.

“We will now take on the challenge of further developing IJburg into a vibrant neighborhood for these new residents.”
