I had the pleasure of working with Phil on the project at the Royal College of Music for about the last 5yrs, on and off. Phil was always very welcoming and could see around a problem, this is especially helpful when the project is to design performance spaces and other acoustically critical spaces where detailing was paramount. I met him on site for some site visits and he was always very friendly to all concerned, he had time to explain the details to everyone even when the questions seemed silly at the time of asking.
I will remember him for his joyful smile which could be even heard down the telephone through his voice.
