The fifth edition of the Provada real estate fair which gets underway today at the RAI exhibition buildings in Amsterdam will see visitor numbers grow yet again, according to director Flip Kerkhoven. 'Last year we had 20,542 visitors and a total surface area of 20,000 m[sup]2[/sup]. Including all the conference rooms, this year the surface area totals 21,000 m[sup]2[/sup] and I expect around 23,000 visitors will come.'
