Custom Home Design Services

We specialize in designing custom homes and realizing ambitious renovations

Experienced Residential Designers in Oakville

We craft exceptional homes that merge modern architecture with timeless elegance. As a top Oakville design firm, we specialize in custom designs that reflect individuality, blending design styles from minimalism to eclectic sophistication.

Recognized among leading Canadian architecture firms, DSD School of Design is inspired by originality. Our approach seamlessly fuses architectural design elements—from transitional to contemporary—ensuring every space is a true reflection of your unique vision.

Renovations, Additions, Facade Upgrades

Part of the joy of residential design is in reimagining existing homes, redefining their presence in a community with contemporary styling or adding new flare with dramatic enhancements. Whether it’s renovation, addition, or façade upgrade, we reimagine spaces with modern aesthetics and functionality.

Our passion lies in redefining a home’s presence within its community, blending design and architectures that enhance both form and function. From contemporary styling to bold enhancements, we take pride in creating distinctive, refreshed spaces.

3D Renderings

The only way to bring a dynamic vision to life is to render a concept on screen or paper and let the idea breathe. A delicate process of revision and refinement is next, but it’s those original drawings that set the foundation for creative achievement. Our detailed 3D rendering process is comprehensive and executed with precision to lay the foundation for the completed custom home designs to follow.

We hired David Small Designs (DSD) for a new custom home design. We were very pleased with the well-thought-out design process and, of course, the beautiful design. However, what really left a special impression was dealing with a unique Variance complication at the Municipality. The DSD planner, David Brown, who worked with us took a calm but methodical approach to first convince the town planner and eventually the Committee that the Variance was simply a Zoning interpretation issue and should be approved (despite local opposition and very unfavourable precedence). Alas, we won, when I was convinced we would not – and it was, in no small part due to the dedicated work of the DSD planner.

We are almost finished with our custom home design and couldn’t be happier about the experience working with David and his talented team. Consistently they have delivered exactly what they said they would, when they said they would. They committed to 6-8 weeks from the start and we are right on target. We live in Colorado and the process working remotely has been seamless. David flew in for our initial meeting which was great to have that personal interaction. For us, like many people however, we are a busy working couple with small children and truly appreciate the speed of having Skype calls. While meeting in person is nice – it takes time out of our busy days to drive to and from. We have the personal interaction “seeing” each other via Skype but do it all much more efficiently. We are thrilled with David and his team, our home design and can’t wait to build and move into our David Small custom home!

We had the pleasure of hiring David Small Designs on three occasions– about ten years ago for a custom home build in Lorne Park; a second time for a sunroom addition; and just recently for a custom cottage design. All three experiences were wildly positive. Each time the designers demonstrated an impressive level of creativity and ingenuity when incorporating our wish list items. Their passion and enthusiasm for our projects were equally matched by their talent and skill. The project managers were responsive, attentive and compassionate. The home in Lorne Park fit like an old pair of blue jeans from the day we moved in. We look forward to building our David Small Design dream cottage soon.
