01 / Profile

Est. Amsterdam, 1985

A family-led group, managed in-house from Breukelen

A family-led owner of commercial real estate since 1985.

Founded in Amsterdam in 1985 by Lars-Erik Magnusson, The Larmag Group has spent four decades acquiring, developing and managing commercial real estate across the Netherlands, Germany, the United States and the United Kingdom — with an accumulated portfolio value in excess of EUR 5 billion over time.

The Larmag Group is the trading name for the corporate group in the Netherlands; investments are made through individual Larmag companies, each with its own identity and portfolio — including the wholly-owned subsidiary LandTech B.V., which carries the group’s move into AI data-centre infrastructure.
