Garden Suite + Main House Renovation

Completed a comprehensive main house refresh and constructed a new 800 sq ft garden suite in Markham, providing modern living for in-laws while updating the existing home.

Challenge

Navigating the complex Markham zoning for an accessory dwelling unit (ADU) proved challenging, especially with specific setback requirements and utility connections. Coordinating two distinct renovation phases—main house refresh and new build—on an active family property also demanded meticulous scheduling and site management to minimize disruption.

Solution

To meet Markham's stringent energy efficiency standards, we utilized spray foam insulation (Roxul Comfortbatt R22 in walls) and installed high-performance Andersen windows in the garden suite. The main house refresh involved durable, low-VOC Benjamin Moore paints and engineered hardwood flooring for longevity, ensuring a cohesive aesthetic across both structures.

Result

The project was delivered on schedule within 16 weeks, enabling the in-laws to move into their new suite promptly. The addition of the garden suite significantly increased the property's market value by an estimated 25%, while enhancing multi-generational living comfort and privacy for the entire family.

“The garden suite turned out lovely, and our in-laws are very happy with the space, especially the large Andersen windows. There were a few minor delays with city inspections near the end, which pushed our move-in date back by about a week, but RenoHouse communicated openly throughout the process. The main house updates were handled efficiently.”
