As of Q2 2016, Dubai has around 8.3 million sq. m. (90 million sq. ft.) of office stock, out of which only about 30% currently qualities as prime. Around 700,000 sq. m. (7.3 million sq. ft.) of additional supply is expected to come online by 2018, with Business Bay accounting for about 30% of this.
However, we expect these figures to contract due to delays and phasing of supply as developers increasingly align deliveries to market conditions.
