Schmidt Hammer Lassen (SHL) is an international architectural firm founded by a group of Danish architects in 1986 in Aarhus, Denmark.

The studio is designing the tallest residential high-rise constructed primarily in timber, known as Rocket & Tigerli in Winterthur, Switzerland, and a new Opera House and Performing Arts venue, known as Green Heart Grand Theatre, in Beijing, China.

The partners include CEO Sanne Wall-Gremstrup, Kristian Lars Ahlmark, Elif Tinaztepe, Kasper Heiberg Frandsen, Mads Kaltoft, René Nedergaard, and Chris Hardie.

The project in Nuuk was followed by first prize in the international competition for the extension of the Danish Royal Library on the harbourfront in Copenhagen.

In 2010, SHL won the competition to design the first permanent premises for the International Criminal Court (ICC) in The Hague, the Netherlands.
