Hal Mann Vella Ltd's new state-of-the-art showroom in Mosta was inaugurated by Prime Minister Lawrence Gonzi during a ceremony that included an audio-visual production of the marble, granite and hardstone importer and manufacturer's development in 55 years. Five years ago, two Vella families parted company and Hal Mann Vella began restructuring. Its workforce has since increased by 30 per cent to include 154 full-timers and 50 full-time sub-contracted skilled workers.
