HIGH5 Haarlem: breaking new ground at record depth

Geothermal drilling for Haarlem's ambitious HIGH5 development has officially launched! Last week marked a significant milestone as we began installing the sustainable energy infrastructure, penetrating an extraordinary 180 meters into the earth: the project's deepest excavation point.

Under commission from HBB Groep, Vaansteris implementing a state-of-the-art geothermal installation for the five residential towers. This infrastructure will deliver year-round climate control to 569 apartments and commercial units, providing residents and businesses with seamless heating, cooling, and hot water through sustainable energy sources.
