Demand surges while supply drops for another consecutive quarter in London's prime West End office market. High levels of lettings and a fall off in construction translated into increased rents and a nine per cent drop in available space for the second quarter of 2000, according to international commercial property consultants King Sturge, who point out that much of the recent rise in demand can be attributed to the dot.coms and e-tailers who are prepared to pay the highest rents to secure prime space. The failure of boo.com served as a reminder to landlords of the hype still surrounding the dot.com sector.
