The builder of London's "Walkie Talkie" skyscraper said adjusted net asset value - a key measure for developers - was 1,129 pence for the first half ended Sept. 30. The company posted an adjusted NAV of 937 pence a year earlier.

From the second half of last year, the adjusted NAV grew 11.5 percent, the company said.

"Extraordinary events aside, we do not expect to see a correction in the balance between supply and demand in London as we deliver our committed speculative schemes," Chief Executive Robert Noel said in a statement.
