Top Ten in a Proteus retail unit at London's Liverpool Street Station City of London The installation of a Proteus retail unit occupied by Top Ten in a prime retail position in the shopping mall between Liverpool Street Station and the Broadgate office development demonstrated the significant added value that can be achieved by all three Proteus companies working together. This site was identified by the agency side of the business with the installation of the Proteus unit being managed by our architectural company. Such was the value built into this site by Proteus that the Top Ten business was purchased by One to One Mobile Phones for a significant sum after only four months of trading.
