British Land has begun development of a new 146,000 square foot office building at Paddington Central.The company acquired the Paddington Central campus early in July 2013 and planning consent for the new property design was originally won back in 2010.Head of office development at British land Robert Samuel said: "We are excited to be starting our development plans at Paddington Central, and are pleased with the enhanced design of 4 Kingdom Street."The campus already attracts high calibre occupiers from a broad range of industry sectors, and is increasingly seen as a natural extension of London's West End office market."Westminster City Council approved changes to the scheme in 2014 to retain the consented bulk and massing while providing increased flexibility to the office floor plates along with better amenities, according to the company.Practical completion of the project should conclude in early 2017.
