David Small Designs

Designing custom homes for 30 years

As a leading Oakville home exterior and interior design firm, we understand that a home is more than just a structure—it’s where lives unfold, relationships grow, and legacies begin.
A home allows us to plant roots in our communities. It’s the literal and figurative foundation of our strongest relationships. The very best designed homes are unique. They stand out just as they seamlessly fit into the surrounding landscape.

The Dusk Home

The Last House

There are those who say a home is merely an asset, a commodity to be bought and sold. But we beg to differ. To us, a home is a platform for our dreams and ambitions.

David Small Designs was built on the idea that a home can be equal parts artistic statement, residence and love letter to the environment that surrounds it. As trusted designers in Ontario, our goal is to create homes that are thoughtfully integrated into the landscape and deeply reflective of their owners.

Designing Inspired Custom Homes Across Ontario — From Urban Lots to Rural Estates

At David Small Designs, we create homes that challenge convention and celebrate individuality. Influenced by everything from 18th-century French châteaux to Frank Lloyd Wright, our designers blend timeless design principles with bold modern architecture.

As a leading name in custom home design in Oakville, Burlington, Mississauga, Toronto, and beyond, we endeavour to explore radical geometry and craft residences using traditional materials like glass, wood, stone, and steel—designed to both stand out and belong.

Modern Home Designs

Those passionate about modern design are on a never-ending search for different. They don’t follow trends, they set them. Their embrace of purity in design—be it the minimalist simplicity of concrete forms or the whimsical use of glass and steel for modern style house. The evolution of what we’ve deemed Natural Modern design is a reflection of their demand for progress, as well as the need for a constant dialogue between buildings and their surroundings—capturing the essence of modern exterior and interior design.

After scouring numerous house plan books and the internet for my dream home plan, I came up empty-handed. One fortuitous day while browsing through Houzz I saw David’s house and I immediately knew this was what I was looking for! I contacted David and after one meeting he was able to capture my vision and I had my house plans a short time later. It was a pleasure to work with David and his team of professionals.

Christina D’Angelo

I decided to start the process with an architect to design my dream home. After lengthy discussions, multiple drafts my project was going nowhere. I found David Small Designs on Houzz and fell in love with his designs. I can’t express enough how happy I am to be working with David and his team. When speaking to David, it felt like he knew exactly what I wanted in house – after only one meeting! David’s team is always there when I need help or have questions. I highly recommend David Small Designs to anyone looking to build a home.

Nancy Kim

An absolute pleasure to deal with DSD. The project is complex with a lot that has unique requirements and zoning. David and his team are excellent listeners and have delivered a design that is exactly us and fits the way we live perfectly. They continue to assist with dealing with the various authorities that need to provide approvals. An exceptional team, across the board!!

You guys are the best!! We loved every interaction we had with every single person in your office. You made our family’s dream and vision a reality.
