Below is a list of architects and designers (in alphabetical order) who have experience designing at least one completed SDU in Hamilton on elsewhere. You can also design the SDU yourself, as several of the earliest SDUs currently under construction. As a property owner, you can submit the plans to the building department yourself without a stamp or BCIN number but you do need to ensure that the design meets the Ontario Building Code.

Harrison Architect – Chris Harrison, OAA (Dundas)

harrisonarchitecture is a smaller, client focussed architecture and landscape design studio located in the town of Dundas, near Hamilton Ontario Canada.  While not all of our projects include a landscape component, most of our work is intimately connected to the site and grounded in its location; urban, rural or often somewhere in between.  It may be an expansive rural setting or a postage stamp sized garden or rooftop, a storefront or a former industrial building; we believe there are opportunities to explore in every situation and set of needs. Our design tools range from basic hand made models to photo realistic 3-D imagery using Revit software.  And many, many hand drawn sketches.  But surely one of our most effective tools is communication. When coupled with thoughtful, stimulating conversations with our clients about their needs and their vision, drawings and models become very insightful and effective design tools at every stage of the project.  With a collective experience of over 50 years, we are skilled, knowledgeable, dedicated and above all passionate about design and the possibilities it offers for your project.  We would love to sit down and find out more about your project vision.

Emma wrote her thesis on laneway housing in Hamilton in 2008 which, after a decade of promoting the idea, has become the new SDU bylaw in Hamilton. They designed the first new SDU to receive a permit under the new bylaw and have designed other SDUs for Hamilton, which are awaiting approvals. She is also the organizer for the active facebook group Hamilton Laneway Suites & Secondary Dwelling Units.

Invizij have developed a feasibility study package for those interested in looking at building an SDU on their lot in Hamilton. For a fee of $1,500 you will receive a site visit, analysis of your lot, existing buildings, and neighbouring lots, a potential massing of an SDU following the bylaw, and costing/ timing info. Due to the demand for feasibility studies and SDU designs, we are narrowing our focus to homeowners seeking affordable housing solutions with their SDU.

We offer BCIN-accredited architectural drawings, ready for permit and/or construction, interior design, interior decorating city planning, and construction consultation services.
