The building is being blasted into the bedrock on a sloping block and will have as much as three floors of filled land on one side. This places special demands on the structure’s load-bearing ability. To reduce the load on the basement wall, a mixture of heavy gravel filler and lighter LECA balls is being used.
The building is constructed with floor layers made of cast-in-place concrete on apartment-partitioning walls, and outer basement walls of prefab concrete. All the floor layers are being fitted with underfloor heating. The concrete frame provides good resistance to the forces in the building, while also making construction fast and simple — which in turn means good acoustic and climate properties in the apartments themselves.
Inhouse Tech is designing and planning the system and building documentation and is also the lead structural engineer for the project.
