Keith Griffiths is a busy man. The chairman of architectural firm Aedas has just returned from Wales, where he is restoring a 900-year-old castle as a personal project, and is overseeing the company's work on the West Kowloon train terminal, Cathay Pacific's new cargo terminal and the new extension to Hong Kong International Airport.
'One thing I'm very aware of is the fact that we only have a certain amount of time to live,' says the Lamborghini-driving father of three.
'I always have that sense of having so much I want to do with so little time to do it.'
The 55-year-old opera lover, who is on the boards of both the Asian Youth Orchestra and City Chamber Orchestra, somehow manages to find the time in his hectic schedule to go waterskiing, wakeboarding and rock climbing to satisfy his craving for outdoor sports.
Griffiths is a firm believer in allotting time to both work and play. 'I learned a long time ago that you can only be as efficient as the people around you, so I delegate like crazy,' he says, explaining that he has 'wonderful people' at work who help him balance his schedule.
'My days are very structured so that I can both work hard and have fun.'
The restoration of the old castle, for example, is a project the architect doesn't mind spending his personal time on.
