Last month, Hypo Real Estate signed up for the 21st floor, totalling 16,500 square feet, paying around £43 a square foot against the £60 Swiss Re hoped for when it began marketing in spring 2003. Landlords who have come down on price on pre-lets have fared better. In November, British Land secured around £45 per sq ft from insurance group Willis for a 25-year lease on yet-to-be-built towers at 51 Lime Street covering 465,000 sq ft.
