Stortorvet 7, Oslo, Norway

The Project
Stortorvet 7 (S7) is a unique development in the heart of Oslo. This area of Oslo is an attractive shopping hub where most high-end fashion brands reside. S7 has the ambition to become the newest central place for shoppers and restaurant lovers. The Stortorvet 7 project includes both revitalization and expansion. The existing building stock of approx. 32,000 sqm has undergone complete rehabilitation and restoration.

The architects from DARK Arkitekter studio transformed five buildings with different qualities and construction principles forming S7 into a modern space for offices and commercial premises in the inner city. The winning concept from the competition in 2013 was based on preserving and reusing the existing building mass and, at the same time, highlighting the buildings' architecture and place in the urban space.

The project involved a significant refurbishment and a series of extensions that unite five distinct existing buildings, each with a unique character and history. The main atrium allows vertical and horizontal circulation through the combined development.

The large, attractive rooftop terrace with an indoor + outdoor restaurant and bar offers an incredible view of the city. It will be the place to meet up, becoming the main attraction of S7.

The large glazing on the second floor of the main façade facing Stortorvet Street has been made of Pilkington Insulight™ Sun Triple insulating glass units. Triple-glazed units with Pilkington Suncool™ 50/25 T toughened high-performance solar control glass as the outer pane, low-e or clear float glass as the middle pane and laminated or toughened glass as the inner pane, provide high light transmittance, high solar hear transmittance (low g value), excellent thermal insulation (low Ug value) offering at the same time safety and/or security.

While on the ground floor, Pilkington Insulight™ Protect insulating glass units with toughened extra clear Pilkington Optiwhite™ T and toughened laminated extra clear Pilkington Optilam™ OW T have been specified for greater transparency.

Triple-glazed units made of Pilkington Suncool™ 50/25 T toughened high-performance solar control glass have also been used for new infill façades facing Karl Johans Gate and Molergata.

On the top part of the building, where rooftop restaurants and winter garden are located, Pilkington Insulight™ Sun Triple insulating glass units made of annealed or toughened Pilkington Suncool™ 70/35 high-performance solar control glass combined with laminated Pilkington Optilam™ Clear, offer great views thanks to the very high light transmittance of the solar control glass.

The glass façades, windows and doors have been supplied by Bolseth Glass. The insulating glass units have been manufactured at the Pilkington IGP plant in Skierniewice.

The Stortorvet 7 building is certified with BREEAM NOR Very Good environmental certificate.
