OUR STORY
Moderna Design Build is defined by a multi-generational legacy of integrity and excellence. Established over two decades ago in North York, the firm was founded on a shared mastery of the building arts between two brothers, whose collaborative vision laid the foundation for a premier building firm serving the Greater Toronto Area. Since a pivotal relaunch in 2008, Moderna has evolved into a comprehensive design-build powerhouse, carrying forward its founding principles of honesty, technical precision, and a profound respect for the families of the homes they build.
Today, our capabilities span bespoke custom homes, substantial renovations, and sophisticated commercial developments. We operate at the definitive intersection of design and construction, offering a turnkey experience driven by elite architectural partnerships and a disciplined project management framework. This ensures a seamless journey from the first blueprint to the final structural inspection.
Our history is personal, and that sense of responsibility continues to guide how we build, collaborate, and support the families who place their trust in our work. We approach every project with a singular goal: to deliver a residence that is as technically sound as it is aesthetically inspired—creating a home that is built to surpass the expectations of the present and stand 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.
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.
WHAT OUR CLIENTS SAY
Custom Home in The Kingsway
Building my custom modern home in The Kingsway was a milestone project, and Claudio was my first and only call. His craftsmanship is outstanding, every finish, line, and design detail reflects pride and skill. But beyond that, it’s his reliability and trustworthiness that truly separates him. He was there from blueprint to final walkthrough, treating the build like it was his own home. Claudio is a rare combination of builder, craftsman, and partner, someone you can trust completely to bring your vision to life and deliver excellence every time. Thanks again, Claudio, appreciate everything you and your team continue to deliver
Co-Branded Franchise – Second Cup & Noodle Box
Claudio and the team at Moderna Design Build are the definition of reliability and craftsmanship. Building two national franchises under one roof required precision, coordination, and creativity, and they delivered flawlessly. Claudio earned my complete trust throughout the process. When challenges surfaced, he was proactive, transparent, and focused on solutions. The final product wasn’t just on time; it was better than imagined. He’s the kind of builder who makes you feel confident the job will get done and done right.
Home Renovation
A major renovation project can easily become overwhelming, but not with Claudio. His team’s workmanship and dependability were second to none. Every step was communicated clearly, deadlines were met, and the quality of work was exceptional. What stood out most was Claudio’s integrity, if he says it will get done, it gets done. You can count on him not just as a contractor, but as someone who genuinely takes pride in the work and stands behind it.
Custom Home in Davisville
In 2020, we engaged Moderna to build a custom home in midtown Toronto. The project presented a number of unique challenges: pandemic-era supply chain disruptions, a narrow urban lot with limited parking, a major construction project underway next door, and a particularly difficult neighbouring property owner. Despite these complexities, Claudio navigated the build with professionalism, diplomacy, and skill. Claudio maintained strong working relationships with adjacent property owners and the neighbouring construction team, helping to minimize friction and keep the project on track. He managed pandemic-related timeline and budget pressures with transparency and flexibility, offering us clear options when adjustments were needed. He successfully incorporated all our must-have design features and provided thoughtful guidance on cost-effective alternatives for other elements. When supply chain issues led to cost increases in certain areas, Claudio proactively identified savings elsewhere to keep the overall budget in check. Claudio assembled and coordinated a talented team of professionals, including an architect, interior designers, and specialized contractors—most notably an expert in whole-home radiant heating. He held all trades to a high standard of workmanship, ensuring that any deficiencies were promptly addressed and that performance issues were resolved through his strong industry relationships. Throughout the build, Claudio remained accessible and responsive to any concerns from neighbours, which helped preserve positive relationships even after construction was complete. He ensured that all inspections were passed, permits were closed in a timely manner, and that supply chain delays did not jeopardize our occupancy timeline— ultimately helping us avoid unnecessary insurance costs.
After we moved in, Claudio continued to support us by addressing outstanding items on our punch list and providing warranty service as needed. He even initiated a one-year post-occupancy review to proactively address any settling-related issues.
We are thrilled with the final result and regularly receive compliments on our home, which is often cited as one of the most beautifully built on our street. Much of that credit belongs to Claudio and the thoughtful, high-quality work he delivered from start to finish.
A Trusted Builder and Partner
I’ve had the pleasure of working with Claudio on multiple projects, and he’s consistently been a reliable and collaborative builder. He’s always available to meet on-site to resolve any issues that arise, and his clear, open communication makes the design and construction process seamless. Claudio’s attention to detail and commitment to quality show in the finished product every time. He’s truly great to work with.
Cure Salon Spa
The Cure Salon Spa build was a demanding project, blending high-end design with technical complexity. Claudio’s craftsmanship, attention to detail, and reliability made all the difference. He approaches each space like it’s his own, ensuring quality from start to finish. His calm professionalism and commitment to partnership turned what could have been stressful into a seamless experience. Moderna Design Build is the kind of team you trust with your vision, and they deliver it beautifully.
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.
