On Sunday, September 28, 2025, the renovated HPT building on the ETH Campus Hönggerberg will open its doors as part of Open House Zurich.
Designed in 1967 by Albert Heinrich Steiner, the research and teaching building underwent extensive renovation in 2024. The renovation shows how historic buildings can be successfully carried into the future and continue to be used: Original floors were preserved, painted exposed concrete walls were uncovered, and new elements were clearly distinguished from the historic fabric. At the same time, contemporary requirements for energy efficiency, research conditions, and accessibility were integrated—a balancing act that has been convincingly successful.
Guided tours of the building provide exciting insights into its history and recent transformation. Felix Messerschmidt (BGP Architekten) and Dominic Bosshard (Ghisleni Partner) lead the tours.
Guided tours: Sunday, September 28, 10:00 a.m.–3:00 p.m. (hourly)
Location: Auguste-Piccard-Hof 1, 8093 Zurich
