More depressing economic news including revised Treasury forecasts of a fall in UK GDP of 3.8% this year has been reflected in a further softening of the central London office market in the second quarter of 2009, according to the latest NB Real Estate Central London office review. The NB review suggests that the IPF forecast of a total return in 2009 of -22.3% in West End offices and a -19.7% return in City offices will not be very wide of the mark. With evidence mounting that property values in prime areas have bottomed out, however, there is increasing evidence of investors positioning themselves to take advantage of the inevitable upturn.
