Poland's property market experienced record demand in 2007, according to a report released by DTZ. The 435,000 m[sup]2[/sup] of take up on Warsaw’s office market was the highest ever recorded. Including renegotiations in the figure and overall take up was 491,500 m2, a 19% rise on the previous year. Strong demand has led to the increasing frequency of pre-lease deals, which accounted for 44% of leasing transactions on the office market. The majority of transactions took place outside the city centre. The low 3.1% vacancy rate is another record figure.
