Kjellander Sjöberg

What Kjellander Sjöberg does

Kjellander Sjöberg Arkitektkontor is a Swedish architecture and urban design practice founded in 1998 and headquartered at Rosenlundsgatan 40, Stockholm. The firm operates three studios — Stockholm (headquarters), Malmö (established 2015), and London (established 2021) — and serves a portfolio that spans all scales from individual buildings and public spaces to large-scale masterplans of thousands of homes. Core service lines include architectural design (residential, mixed-use, cultural, and infrastructure projects such as the award-winning Styrmansbron bridge), urban planning and masterplanning (Hartree in Cambridge, 5,600 homes; Tendring Colchester Borders Garden Community, 7,750 homes; Gäddviken in Nacka, ~1,600 homes), transformation and heritage adaptive reuse (notably Gjuteriet, a 1910 foundry converted for Oatly's headquarters using circular economy principles), and public realm / placemaking. Supporting these are the proprietary KS Workbook process guide (developed with John Manoochehri of Resource Vision) and the No Border Studio sub-brand for research-led urban design.

The firm generates revenue exclusively through commissioned professional services — fixed fees, percentage-of-construction-cost fees, and hourly consulting — won primarily through participation in open and invited architectural competitions. Clients are B2B and split across two main segments: Swedish and UK municipalities and public authorities (Stockholm Stad, Malmö Stad, Uppsala Kommun, Enfield Borough Council) and property developers and housing associations (Besqab, Wallin Bostad, Atrium Ljungberg, Klövern, HSB, LandsecU+I, Latimer/Clarion Housing Group, Humlegården, Uppsalahem, Skanska Fastigheter). The practice is led by founding directors Mi Inkinen (Managing Director), Stefan Sjöberg, and Ola Kjellander, with regional directors in each studio and a curated team of approximately 24 named professionals. The firm is privately held with no external investment, parent company, or subsidiary structure beyond the in-house No Border Studio sub-brand.

The go-to-market combines competition-based acquisition, project reputation and portfolio marketing, thought leadership through international lectures (Venice Biennale, Archtober NYC, Politecnico di Milano) and the in-house Shop Talk event series, and earned media via architectural publications (Arkitektur, Forbes) and industry awards (Kasper Salin Prize, Malmö Stad Stadsbyggnadspris 2023, EUmies Awards 2024, The Pineapples Awards). Geographic scope is primarily Sweden and the United Kingdom, with selected international projects in Austria and the Czech Republic. The firm has received 30+ documented competition wins and award recognitions spanning 2016–2026, positioning it as a recognized competitor in the Nordic and UK sustainable architecture and masterplanning market.

Core offering

Kjellander Sjöberg is an architecture and urban design practice delivering architectural design, urban masterplanning, transformation and heritage reuse, and public realm design services for municipalities, public authorities, and private developers. The firm works across all scales — from individual buildings and public spaces (e.g., Styrmansbron bridge, Gjuteriet transformation) to large masterplans (e.g., Hartree in Cambridge with 5,600 homes) — using its proprietary KS Workbook process methodology and BIM-based project management to integrate sustainability and circular economy principles from the earliest project stages.

Product overview

Kjellander Sjöberg is an architecture and urban design firm offering a unified portfolio of services rather than a modular software platform. The core offerings span architectural design (residential, commercial, cultural buildings), urban planning and masterplanning, transformation of heritage buildings with circular economy principles, and public realm/placemaking. Supporting these are proprietary methodologies like the KS Workbook process guide and specialized sub-brands including No Border Studio for urban design and masterplanning. The Work Shop platform delivers knowledge exchange through Shop Talk events, Think Tank research, and the Shopfront Gallery exhibition. Projects range from individual buildings (e.g., Styrmansbron bridge, Gjuteriet transformation) to large-scale masterplans (e.g., Hartree in Cambridge with 5,600 homes, Tendring Colchester Borders Garden Community with 7,750 homes).
