Vinkelbygget is one of three commercial buildings that together make up Kjelleveien 21. Vinkelbygget is a low-energy building that extends over 10,633 square meters

The developer has emphasized energy reduction, flexibility, and universal design. The offices are adapted for today's tenants and ready for tomorrow's use. It is a so-called pioneer building with financial support from Enova. The building has large windows, all of which are of the low-energy type. The building has an energy rating of A and a heating rating of Green. All offices and meeting rooms are equipped with VAV control (Variable Air Volume) and Presence Sensor. This means that the ventilation air volume is adjusted at all times. All sanitary facilities are equipped with water-saving fittings/equipment.

Tenants have their own gym, and there is a staffed canteen on the 4th floor. The elevator is attached to the building. The main access road to Tønsberg centrally locates the property, and it is a short distance to the center and the pier in Tønsberg.

The property is closely located to public transport with only a few minutes' walk to the bus stop. Travel time by train during rush hour will take 63 minutes with the new Flirt train. Rustadbrygga in Horten, where you can take the ferry to Moss, is a 25-minute drive from Kjelleveien 21. Sandefjord Airport Torp, where there are excellent connections nationally and internationally, is 24 minutes away.
