Located in the north-east of Oslo, the area of Hasle is experiencing a new wave of development. Drawing upon Hasle’s wealth of historic industrial buildings, the developers of the properties wished to contribute to the creation of a new neighborhood of office buildings, commercial buildings, cultural attractions, food stores, cafes, restaurants, and residences while still embracing the industrial properties of the site.
SPACEGROUP delivered a design and strategy that embraced the uncertainties of the project and provided a range of possible programs, floorplans, and phasing to counter a number of possible development scenarios. The starting point required a strategy that balanced optimal floor plates, façade-to-floor-area ratios, effective and flexible building volumes, and the proper placement of program typologies to ensure maximum value for stakeholders.
The challenge to negotiate the site’s exceedingly fat and unwieldy building plots was central to the brief, and the ambition was to create the most efficient and flexible spaces possible while still utilizing the maximum allotted building area. To meet this challenge, as well as Norway’s strict daylighting requirements, SPACEGROUP developed two separate strategies for the two building plots. In keeping with the tight metrics desired for the project, all three resulting buildings have an underlying numerical grid (1.80 M – 3.60 M – 5.40 M – 7.20 M) and straightforward structural system to guarantee maximum flexibility and area use.
For site K4, the site of the proposed hotel and adjacent office space, a diagonal cut was employed to maximize façade surface area for daylighting purposes and to generate the most efficient relative floorplans for both programs. The hotel and offices are connected by a bridge of shared programs – a gym, bar/café, and larger seminar and conference spaces. A 4.3-meter height change in elevation over the short axis of the site allowed for a partially submerged ground level with dually purposeful support functions such as a full kitchen and laundry. The diagonal cut allows for a passageway of retail to support more public interaction and accessible street frontage for retail.
Site K5 employed a highly tailored, thin atrium that breaches the south façade. Cut through the analysis of hundreds of tested permutations, this specific atrium design allows for the maximum amount of daylight for the smallest loss of floor area. The atrium itself is an environmental half-climate, engineered through a collaboration with Atelier Ten in London, allowing the building to retain heat in the winter while self-ventilating during the summer months. With a structural approach involving stiffening of the atrium and exterior facades, the floorplates are fully liberated and a multitude of office configurations and tenant divisions (from 1 to 5) is possible. Upon further drone analysis, SPACEGROUP proposed shifting the building height up by 6 meters in order to gain views of the Oslofjord.
The building masses are carefully calibrated to allow maximum sunlight into public outdoor spaces, and encourage residents and workers to gather and linger in outdoors, using the facility’s range of cafes, retail, and public areas to foster community and a neighborhood identity.
