Kronløb Island - an aesthetic gem in the middle of the water

Kronløb Island - an aesthetic gem in the middle of the water

When the new island district ‘Kronløbsøen’ is completed, it will be with balconies in ultra high performance concrete. In 2022, Hi-Con will supply and install 220 balconies with embedded brick shells for this new island.

The assembly of the elements has already begun. Our good partner RG stålbyg is responsible for the mounting. 


Behind the new island district is the project company Kronløbsøen Projekt P / S, it was designed by Vilhelm Lauritzen Arkitekter A/S and COBE and built by NCC Denmark. The impressive project will complete the vision for the "Århusgade" district in Copenhagen's North Harbor - a vision that Hi-Con is pleased to be allowed to contribute to.


The choice of Hi-Con as a subcontractor is based, among other things, on total economic considerations, where time is a significant factor. When Hi-Con is involved as a subcontractor in a construction project, customers are offered a complete package of consulting, design, manufacture, delivery and final assembly of the elements. Thus, Hi-Con can save its customers unnecessary contract gaps and thus the extra time and resources often associated with handling and coordinating multiple subcontractors.


The elements in ultra high performance concrete

Although the construction will be completed with 220 balconies in ultra high-strength concrete, the balconies will be delivered in 305 balcony elements, each of which consists of one balcony slab and three parapets with embedded brick shells on the outside. Due to the length and design of the balconies, some of the balconies will be divided into several elements and subsequently assembled during mounting. The balconies measure up to 13 meters in length and 4.5 meters in depth, while several of the balconies go around the corners of the buildings. The balcony slap itself will be made with a plate thickness of 100 - 125 mm and cast in gray ultra high performance concrete.

We are incredibly proud to contribute to yet another climate-conscious quality construction in this area. Fortkaj, which was recently completed as a DGNB gold-certified project, can be seen as a neighbor to Kronløbsøen.
