After 20 years of residential architecture practice, I'm pleased to announce I'm joining my wife in retirement - off to explore a new chapter! Other than the projects underway, I'll not be taking on any new work. Thanks to all of the contractors, interior designers, engineers and consultants that I've had the pleasure of working with these past years. A special thanks to all of my clients for their trust and enthusiasm in the designing of their dream homes.
