Case Study: Building a Garden Suite in Scarborough, Ontario | Vanguard Build Limited
Introduction
At Vanguard Build Limited, we specialize in high-quality custom home builds and renovations across Scarborough, Ontario. This case study explores the process and considerations involved in constructing a garden suite—also known as a backyard suite or granny flat—for a homeowner looking to create additional living space for aging parents while staying within the City of Toronto’s zoning and building regulations.
1. Project Overview
Objective: Build a 700-square-foot garden suite to provide independent living space for aging parents while enhancing the property’s value.
Location: Scarborough, Ontario—a primarily residential area with varying lot sizes.
Budget: Estimated at $150,000, covering construction, permits, and utility connections.
Timeline: 12 months (from conceptualization to completion).
2. Research and Planning
Understanding Local Zoning & Permit Requirements
As a licensed general contractor and home builder in Scarborough, we conducted extensive research to ensure compliance with Toronto’s garden suite bylaws. Key zoning considerations included:
Minimum Lot Size: The property met the minimum 3,000-square-foot requirement for a garden suite.
Setbacks: The suite had to be placed at a designated distance from property lines and existing structures.
Height Restrictions: The suite was designed to stay within the 4-meter (13-foot) height limit to maintain neighborhood aesthetics.
Building Permit Process: We obtained a building permit by submitting architectural drawings, site plans, and a detailed construction scope for city approval.
3. Design Considerations
The design phase focused on functionality, sustainability, and accessibility while ensuring seamless integration with the existing property.
Key Design Elements
Space Efficiency: The 700-square-foot layout included:
1 bedroom
1 living area
Kitchenette
Bathroom
Sustainability: Energy-efficient insulation, LED lighting, and water-saving fixtures reduced long-term costs.
Privacy: Landscaping and fencing created a buffer between the main home and the garden suite.
Accessibility: Wider doorways, zero-step entry, and an accessible bathroom accommodated the homeowner’s elderly parents.
4. Construction Phase
With permits secured and plans finalized, we moved forward with the construction process.
Site Preparation
Lot Clearing: Removed debris, trees, and obstacles.
Excavation & Foundation: Laid a concrete slab foundation and completed utility connections (electricity, water, and sewage).
Building Process
Framing & Roofing: Constructed a wood-framed structure with a pitched roof that matched the main house.
Utilities & Plumbing: Installed energy-efficient electrical, HVAC, and plumbing systems.
Interior Finishing: Completed drywall, flooring, cabinetry, and countertops to create a modern, inviting space.
Landscaping & Outdoor Space: Integrated the suite into the backyard with walkways, a patio, and privacy fencing.
5. Challenges and Solutions
Building a garden suite presented several obstacles, which we successfully navigated.
Zoning Restrictions: The original zoning bylaws did not permit garden suites in the neighborhood.
✅ Solution: We worked with a local urban planner and the City of Toronto to apply for a zoning bylaw amendment.
Space Constraints: Fitting a garden suite on a smaller lot while maintaining outdoor space was a challenge.
✅ Solution: We optimized the layout for vertical storage and used landscaping techniques to maintain an open feel.
Budget Overruns: Unexpected costs arose for utility connections and landscaping.
✅ Solution: We adjusted the budget with cost-effective landscaping solutions and negotiated with subcontractors.
6. Final Outcome
The garden suite was completed successfully, providing a comfortable, independent living space while increasing property value.
Key Results:
✔️ Property Value Increase: Estimated 15-20% boost in home value.
✔️ Family Comfort: Aging parents now enjoy privacy and independence while remaining close to family.
✔️ Sustainability Benefits: The suite’s eco-friendly features reduce energy costs and carbon footprint.
