Olsson Lyckefors Arkitektur, formerly known as Bornstein Lyckefors Arkitekter, is a Sweden-based architectural office founded by Per Bornstein and Andreas Lyckefors in Gothenburg in 2011. Johan Olsson has been a partner since 2012. The company opened a studio in Stockholm in 2018. At present, Olsson Lyckefors employs 34 architects, interior designers, students and staff members in Gothenburg and Stockholm.

The office is engaged in a broad spectrum of projects ranging from research studies to architecture and interior design for private, corporate, and public clients. Olsson Lyckefors uses contemporary digital tools and traditional methods in every phase of design development from early sketches to finished buildings.

With focus on architecture, the essence of the office's business is the formulation of experimental spaces and the search for narrative qualities in strategic, poetic, and communicative architecture.

The office's work has been recognized and awarded both nationally and internationally. Olsson Lyckefors was nominated for villapriset 2017 by the Swedish Association of Architects, winner of WAN Awards 2017, winner of the biannual Rödfärgpriset 2018, winner of Häuser Awards 2019 and were finalists in Gothenburg building of the year 2019 with the new HQ of Polestar cars, Brf Qville and villa Radal. The office has been awarded several nominations for Guldstolen, the prize for best interior architecture in Sweden, and had two projects nominated for Träpriset 2020. Träpriset is awarded every four year for best wooden architecture in Sweden.
