Ideas About Projects


DPAI is an architecture, interiors and urban design studio based in Hamilton, Ontario. The purpose of our practice is to create sustainable work environmentally and socially.

Our practice approaches sustainability through a holistic lens, ranging from environmental design to sustaining our communities.

Our mission is to Shape the World. We combine a holistic design approach with people-first sensitivity; always maintaining focus on the end-user experience.

Our values are more than catch phrases. They are the guiding principles that inform each decision and inspire our design and project management approach. They guide and empower us as architects, designers, partners and collaborators in our quest to create functional and accessible spaces for those who inhabit them.

The construction and operation of buildings has a huge impact on the carbon footprint of humanity. The way we plan a community is a determining factor in the health and well being of its inhabitants. We fulfill our mission by choosing to create a positive social, economic and environmental impact through our work.

Our portfolio includes award-winning projects across multiple sectors and range in size from feasibility studies, master planning, urban plans, interior renovations and new builds. Our diverse experience affords us the ability to combine ideas from disparate areas to create novel solutions to complex design challenges.

“I and my colleagues have worked with a number of architects over the years on everything from small renovations to large multi-building developments. In that time we have never worked with a firm that addressed our needs over imposing their ‘vision’ in the way that DPAI has. That is not to say that DPAI hasn’t been prepared to propose alternatives to what we had contemplated, but that the entire process has been respectful of what Good Shepherd was trying to achieve. Also, in so many cases, the principal of an architectural firm is what one often ‘buys’ and the strength of their support team is often difficult to judge and in my experience, has in some cases been inadequate. I can say that there is a very strong team at DPAI.

Finally I want to mention something about the actual development process that has been unique in our experience with DPAI. Developing, whether through renovations or by starting new is fraught with challenges and frequently leads to some very difficult conversations among the design team. I and others that I’ve worked with have all commented on how different it has been working with DPAI where we can have the ‘tough’ conversations without them being ‘difficult’ ones as well. This in and of itself is one of the best reasons that I can think of to work with someone and we will continue to work with DPAI in the future.”

Alan J. Whittle, Director, Community Relations & Planning Good Shepherd Hamilton

“It has been a pleasure to work with DPAI on our art studio expansion and renovation project at McMaster University. DPAI’s friendly consultation throughout the process was effective and much appreciated. They applied their expertise to our unique demands, arriving at aesthetically dynamic solutions for a complex network of work spaces. The result is a functionally and visually cohesive space.”

Judy Major-Girardin, Professor and Project Team Lead, McMaster School of the Arts

“ In all the projects we have worked with David Premi and his team on we have found their consistent commitment to understanding our needs and then translating those into innovative designs that addresses our needs and aspirations in ways we did not envision. They have brought to every project an attitude of being our advocates while being willing to take chances on providing design solutions that help us create sustainable and exciting solutions. It has been very rewarding to work with the DPAI team. Every project has challenges and having DPAI on our side has helped us overcome the challenges we have faced.”

Paul Takala, Chief Librarian/CEO Hamilton Public Library

“Theatre Aquarius, like many institutions in the non-profit sector, has big dreams, grand visions, and limited resources. That is exactly why a partner like DPAI architecture has been so essential for us. They share our inspiration, and have the flexibility and responsiveness to help us actualize those ideas, while taking innovative approaches to ensure that the finished project reflects the vision, and not the roadblocks that were overcome along the way.”

Lorna Zaremba, General Manager Theatre Aquarius

“DPAI were the lead architects for the renovations to Hamilton’s Central Library. The building had been a prime example of seventies brutalist architecture, with all of the dark and cold connotations. David Premi and his team saw the building’s potential, which we didn’t. I have worked with many architects on many projects; this project was the first time I found myself letting go, confident that our hopes and visions for the building were being heard and were being translated into a workable plan combined with an amazing AWE factor. The result is a remarkable, iconic building that the public has embraced as their own. One of my favourite moments, as a librarian, was the day it re-opened after eighteen months of renovations. I stood, with David, just inside the front doors and watched people, with delight in their eyes, enter and quickly understand - intuitively - each space. Use of the building skyrocketed and has remained high ever since the transformation performed by David and his team.”

Ken Roberts, former Chief Librarian Hamilton Public Library

“Thank you all SO MUCH for all your work on this project! We have all added a little bit of ourselves to the history of this building.”

Jennifer Stacey, General Manager Ryerson Student Centre

“From start to finish, the team from DPAI was amazing to work with. Their attention to detail, commitment to quality work and focus on customer service resulted in an outcome that far surpassed our expectations. We were renovating an existing use research and educational space in an older building on a limited budget. The team from DPAI took the time to thoroughly assess our current and future needs and managed to channel our vision into design features that have had a lasting positive impact on all users of the space. We have found that the space is adaptable to our needs, robust in terms of utilization and comfortable and energizing to work in.”

Maureen Jane MacDonald Ph.D., Professor & Acting Chair Department of Kinesiology, Acting Director PACE

“It was a pleasure for us to work with architects who understood so much about student needs and have a solid grounding in trends in the evolution and transformation of libraries. David and his team were very collaborative and responsive to our needs. They were ultimately able to unlock the potential within the constraints of a challenging building and were able to translate our vision into a dynamic learning space. The result resonates deeply with our students who have commented that the new space motivates, inspires and energizes them. Their only complaint is that we haven’t yet done the same with the rest of the library. I would welcome the opportunity to work with DPAI again would recommend their team without hesitation.”

Chief Librarian Mark Robertson Brock University

“I was impressed on many levels with the DPAI team. They are professional, responsive, respectful and did a very good job of engaging all the stakeholders in the process. They were flexible and accommodating to the changing scope and requirements of the project. The space has been transformed from a 20 year old traditional learning environment to a modern, energetic and creative space that attracts students from all across campus.”

Paul Armstrong, Vice President, Academic Mohawk College
