Lorentz Harboe Ree graduated from the architectural department at the Norwegian Institute of Technology (NTH) in 1915. In 1918, after two years as an assistant at an office in Bergen, he established his own practice in Oslo. There, he collaborated first with Harald Aars and from 1920 with Carl Buch to create memorable buildings such as Kinopaleet, Bislet Bad, Nore Power Station, the Vigeland Museum, and the kiosks Tyrihans and Palladio for Narvesen.
Ree was also an illustrator, creating, among other things, the insignia for Polyhymnia. He exhibited at the Jubilee Exhibition at Frogner in 1914 and designed some furniture. His works are featured in the National Gallery. In 1916, he published the book "Østraat" together with art historian Fredrik B. Wallem.
In 1923, Lorentz Harboe Ree and Carl Buch emerged victorious in an architectural competition for new newspaper kiosks organized by Narvesens Kioskkompani. Their winning entry was the design for the so-called Tyrihans kiosk, which was subsequently erected in various locations across the country. As of 2018, one specimen of the Tyrihans kiosk remains on display at the open-air museum of the Norwegian Folk Museum. This particular kiosk was relocated to the museum in 1986 from its original site at Carl Berners plass in Oslo, making it the sole surviving example of these kiosks.
In 1926, Lorenz Harboe Ree and Carl Buch were honored with the Houens Foundation's diploma for Gustav Vigeland's studio and museum at Nobels gate 32. Additionally, they jointly received the Sundt Prize in 1938 for the residential complex at Gabels gate 46 and Vestheimgata 6 in Frogner, Oslo.
