Property group British Land has confirmed that it has fully let its recently completed development at 39 Victoria Street in London.The letting of the nine-storey building follows a number of others for the company and means its West End office portfolio now has a 96% occupancy rate, up from 88% at 31 March.Tim Roberts, the company's head of offices and residential, said: "We have continued to see good letting momentum across our London office portfolio which reflects the high quality spaces and environments we have created along with improving occupational demand."With little new product coming to market over the coming years, we are pushing forward with our near-term pipeline."
