At CSM Design Build Inc., we create exceptional living spaces that bring together quality, efficiency, and contemporary design. Backed by more than 75 years of combined expertise, our team transforms vision into reality with a disciplined, end-to-end approach that prioritizes both performance and precision. As an integrated residential development company, we unite planning, design, and construction under one cohesive structure, ensuring every project is executed with clarity, accountability, and consistency from concept through completion.
Our work is grounded in a clear purpose: to respond to the growing demand for well-designed, attainable housing across London and the surrounding region. Drawing on decades of experience in property management, development planning, and construction execution, we deliver projects that are not only thoughtfully conceived but strategically positioned for long-term success. Supported by trusted local partners and a strong reputation in the marketplace, we are committed to creating opportunities that generate meaningful returns while contributing to the fabric of the communities we serve.
We are dedicated to building more than residences, we build vibrant, connected communities. This commitment is exemplified through developments like Southdale Crossing, where intentional design, livability, and location come together to enhance everyday life. Each project is approached with a focus on enduring value, balancing market demand with design integrity to create spaces that resonate with both residents and investors alike.
Driven by meticulous planning, strategic partnerships, and an in-house team of skilled professionals, CSM Design Build delivers with confidence and purpose. Our mission is to plan, design, and build high-quality residential townhomes and high-rise apartment units that meet real market needs, deliver strong investment potential, and create places where people can truly live and thrive.
With over 30 years in the industry, my journey has been shaped by one consistent belief: meaningful development is never built alone. It is built through collaboration, trust, and a relentless commitment to doing what you say you will do.
At CSM Design Build Inc., that philosophy is at the core of everything we undertake. We are intentional about who we partner with, bringing together proven experts across design, construction, planning, and community development to ensure every project is grounded in both vision and execution. Our strength lies not only in what we build, but in how we build it, with integrity, accountability, and a shared standard of excellence.
South London represents an exciting opportunity, and one we approach with both responsibility and ambition. Our upcoming residential towers are more than new developments, they are a reflection of our commitment to the community. We see these projects as a chance to contribute thoughtfully to the city’s growth by delivering high-quality, attainable housing that responds to real needs while elevating the standard of living.
We are proud to play a role in shaping spaces where people can live, connect, and thrive. And as we look ahead, our focus remains clear: to continue building with purpose, surrounding ourselves with the right people, and creating developments that London can be proud of for years to come.

15 Stacked Townhomes (30 Units)
Expected completion in Fall 2027
Southdale Meadows introduces a refined approach to modern low-rise living, offering an exclusive collection of 15 thoughtfully designed stacked townhomes in London, Ontario. This boutique development addresses the “missing middle” in today’s housing market, blending the privacy and functionality of traditional townhome living with the efficiency of a stacked configuration. The result is a highly livable, design-forward community that delivers both comfort and long-term value in a sought-after location.
Featuring a strategic mix of accessible two-bedroom lower units and expansive four-bedroom upper residences, Southdale Meadows is purpose-built to meet the needs of today’s buyers and investors. The larger layouts present a distinct competitive advantage, appealing to growing families as well as those seeking strong rental performance in the student and multi-tenant market. Positioned on a prominent arterial route at 1236 Southdale Avenue, the development offers seamless connectivity to retail amenities, transit, and major highways, making it an ideal opportunity for those looking to invest in a well-located, high-demand asset without the maintenance of a detached home.
