DUBLIN building contractor G & T Crampton Ltd has moved its headquarters on a temporary basis to the Sandymount Buildings, Simmonscourt Road, Dublin 4. The move is being made to allow the company to develop 115,000 square feet of office space on the site of its present offices at Shelbourne Road. Crampton will eventually move back to the Shelbourne Road site, which will be known as the Ballsbridge Centre.
