Amsterdam's office market has reached a turning point according to research by real estate advisor Savills. After the stability that has characterised the city's rental levels in the last three to four years, 2006 signalled the turning point for Amsterdam’s office market, with rents starting to increase and rising an annual 10% in the second half of 2006. 'Leasing activity and prime rents are increasing and positive economic outlook should sustain this trend. We expect further positive rental growth in 2007,' says Savills Research' director Roderik Schuwer.
