OUR STORY
Moderna Design Build began as a small family venture in North York more than two decades ago. What started with two brothers and a shared interest in architecture grew into a trusted building firm serving the Greater Toronto Area. When the company was relaunched in 2008, it carried forward the values that shaped its earliest work: honesty, precision, and a genuine respect for the homes families create. As Moderna Design Build evolved, so did its capabilities. The company now manages custom homes, major renovations, and commercial projects from design to completion. Clients work with a team supported by strong architectural partners, organized project management, and clear communication at every step.
Our history is personal, and that sense of responsibility continues to guide how the company builds, collaborates, and supports the families who place their trust in its work. Every project is approached with the goal of creating a home that feels true to the people who will live in it and strong for the years ahead.


OUR FOUNDER
Claudio Petitti, Founder & President
For Claudio Petitti, the art of building is foundational – a discipline defined by the pursuit of architectural permanence. Raised within the residential building sector, Claudio developed an early, intuitive understanding of the craft that eventually evolved into a lifelong pursuit of building excellence. A graduate in Architectural Technology, Claudio balances a creative’s vision with a technologist’s precision – a synergy that has come to define the Moderna Design Build standard. Today, with over 25 years of expertise, his personal involvement in every project ensures that each residence bearing the Moderna name is a masterclass in quality, integrity, and elevated design. Under his leadership, ambitious concepts are transformed into enduring residential legacies.
Our history is personal, and that sense of responsibility continues to guide how the company builds, collaborates, and supports the families who place their trust in its work. Every project is approached with the goal of creating a home that feels true to the people who will live in it and strong for the years ahead.
This approach isn’t a slogan for him. It reflects the pride and personal responsibility he brings to each build. Over the years, Claudio has collaborated with respected architectural studios and completed private residential work for well-known Canadian figures. Clients value his honesty, his attention to detail, and the way he explains the construction process with clarity and practicality. Every home that carries his name represents years of experience, a commitment to thoughtful building practices, and a belief that quality is achieved through daily discipline, not shortcuts.
“If I won’t sign my name on it, your home is not ready.”
OUR MISSION
Our mission is to create homes and spaces that feel thoughtful, lasting, and true to the people who live in them. We focus on clarity, open communication, and a process that supports clients from the first conversation to well after move-in.
Every project is led with accountability and a steady hand. We aim to offer a building experience where clients always know what is happening, why it is happening, and how their home is progressing. Our work reflects a simple belief: when the details are done with care, the entire home stands stronger.

Our Values
BUILDING FOR THE COMMUNITY
Our work extends beyond construction sites. We are proud to support local sports programs, neighbourhood events, food drives, and small improvements that enrich the Humberlea And West Toronto community. Giving back is part of who we are. Moderna Design Build continues to grow, but our promise remains the same: thoughtful planning, strong building practices, and a home that reflects your way of living.
