Thranekær Rådgivende Ingeniører has acquired Peter Jahn & Partnere, a Copenhagen-based engineering consultancy specialising in the renovation, maintenance and improvement of existing buildings.

The acquisition of Peter Jahn & Partnere marks Thranekær’s eighth acquisition since the company was founded in 2025. Peter Jahn & Partnere brings 35 employees to Thranekær and strengthens the group’s specialist capabilities within the existing building stock.

Just as importantly, we have found a company that shares our values and our ambition to create value through strong advisory.”
