What NIELSTORP+ arkitekter does

The firm delivers architecture, place development (urban planning/landscape), and interior design services for property developers, hospitality operators, commercial enterprises, and public sector clients across Norway and selected international markets. Its portfolio spans small-scale residential renovations through to landmark commissions, most notably the 245,000 m² China Eastern Airlines headquarters in Shanghai, demonstrating capacity to operate across a very wide range of building typologies, scales, and geographies.

The practice's technical stack is built on Autodesk Revit as the primary BIM authoring tool, supplemented by AutoCAD and SketchUp for design and visualization work. It has integrated virtual reality (VR) for client presentations and operates a dedicated internal AI team focused on rendering and visualization workflows. It holds Miljøfyrtårn (Eco-Lighthouse) environmental certification and employs BREEAM-accredited personnel, supporting sustainable design delivery. The firm currently runs offices in Oslo (headquarters) and Tromsø, with the Tromsø satellite established in September 2023 to serve Northern Norway.

Revenue is generated project-by-project, typically structured as a percentage of construction cost or fixed fees tied to specific design phases. Business development is sales-led, with work won through competitive tenders and direct commissions from repeat clients. The client roster includes China Eastern Airlines, Arctic Sensation AS, Coop Nord, Stiftelsen Martina Hansens Hospital, Nordic Group AS, Sparebank 1 Nord-Norge, and Avinor (Oslo Airport/Radisson RED). The firm employs approximately 40 people and operates without public revenue disclosure.
