"Cyril's skills and experience match with our passion to deliver healthy homes that are kind to the environment and almost free to run," he said.
"He'll have a hands-on role and will be involved in the design and installation of the European Passive House certified ventilation systems that are fitted to every eHaus.
"Part of the internship involves practical on-site work to develop his own experience."
