Radio transmitters and mobile phone masts are situated on the roof . During the 2014 NATO summit a security forces command and control team was housed temporarily in the building , with the top floor and roof being used as an observation post . In 2017 the building was sold as party of a £ 6.5 M deal and is planned to be developed into a 163-bed Mercure hotel
