London named among top four most expensive office markets in world

London's West End, Mumbai, the City of London and Moscow are the top four most expensive office markets in the world, according to CB Richard Ellis Research's semi-annual Global Market Rents survey. The report tracks the world's most expensive markets as well as markets with the fastest growing rents over the past 12 months. The top ten most expensive markets list is unchanged over the last six months; however, several cities' rankings have changed. Mumbai's Nariman Point, at $189.51 (occupation cost in US$/sq. ft./annum used throughout this release), rose three places to second. At $180.78, Moscow joined the top five, jumping two spots to fourth overall. Tokyo's Inner Central Five Wards and Outer Central Five Wards fell to fifth and sixth, respectively. Midtown Manhattan is the priciest market in North America, at $100.79, and ranks #12 worldwide.
