Our Company

Winner of Best of Houzz 2016 for Client Satisfaction.

Duffy & Associates Design Build Ltd. employs approximately 15+ full time staff. We provide complete construction management, design and consulting services as required for every project we take on. Duffy & Associates manages projects of many scales and across many building types — residential, commercial and institutional projects, from complete buildings to detailed renovations. Our work covers the spectrum from design to turn-key project delivery.

Over the years we have worked with many notable firms including Superkul Architect, AKB Architects,  Ian MacDonald Architect, Shim Sutcliffe Architects, Paul Raff Studio, AgaThom Architects, Partisans, Natale and Scott Architects, and others.

We constantly pursue more effective ways to integrate design with construction: ideas with execution. We do so with best-practices in construction management, clear design principles and new building methods and technologies. This applies to all projects, from our most custom buildings to our simpler renovations.

Employing green building practices and systems wherever possible, we offer comprehensive consulting to best inform our clients’ understanding of, and opportunities to embrace green building solutions. We have certification in the original R-2000 program and have begun integrating LEED-based standards throughout all of our work.
