Danish Modernism with a Timeless Legacy.

By Lassen is a Danish design brand focused on the iconic creations of brothers Mogens and Flemming Lassen – two of the most influential architects and designers in Danish Modernism history. The brand was founded in 2008 by the Lassen family with the aim of preserving the brothers' exceptional design heritage and making it relevant again for the modern living environment.

Mogens (1901–1987) and Flemming Lassen (1902–1984) are considered pioneers of Danish Functionalism. Their work, characterized by clear lines, well-considered proportions, and a tireless quest for simplicity, earned them numerous awards and international recognition. Many of their designs – such as the iconic Kubus and Frame – are now considered absolute classics of Scandinavian design.

Today, By Lassen is led by Søren Lassen, Mogens' grandson. He safeguards the legacy of his grandfather and great-uncle and expands the collection with designs by other designers that seamlessly align with the functional, sleek, and timeless Lassen signature.

With a deep commitment to quality, craftsmanship, and simplicity, By Lassen brings the modernist spirit of the 1930s into the present day—and into interiors around the world.
