Building a garden suite in Toronto? Konstruction Group provides the framing, insulation, and drywall services that form the structural backbone of your backyard dwelling. Whether you're a general contractor building garden suites for clients or a homeowner acting as your own GC with permits in hand, we deliver the trade work that gets your project from foundation to paint-ready walls. We've completed dozens of garden suites and laneway houses across Toronto - from tight Leslieville lots to spacious North York properties.


A garden suite is a self-contained residential unit built in the backyard of an existing home. Toronto legalized garden suites city-wide in February 2022, allowing homeowners to add rental income, house family members, or create flexible living space. Garden suites differ from laneway suites in that they don't require laneway access - they can be built on any qualifying residential lot. Typical sizes range from 400-1,000 square feet, and they must meet Ontario Building Code requirements for full dwelling units including bedrooms, bathrooms, kitchens, and separate entrances.
If you're a GC building garden suites for clients, we can be your reliable framing subcontractor. We understand the coordination required on tight residential sites - showing up when promised, working efficiently, and communicating proactively about scheduling. Many builders use us for their projects, bundling framing with soundproofing and fireproofing to keep one crew on site and simplify coordination. We carry $10M liability insurance and full WSIB coverage, so your projects are protected.
Many Toronto homeowners manage their own garden suite projects to save on general contractor fees. If you've got your permits and foundation in place, we can handle the framing, insulation, and drywall - three major trades under one contract. For insulation, we offer spray foam for maximum energy efficiency or traditional batt options. For structural support, we install steel beams where open floor plans require them. You'll still need to coordinate other trades, but we make the structural phase straightforward.
Laneway suites face unique challenges: limited access for material delivery, tight spaces for crews to work, and coordination with existing structures. We've framed laneway houses throughout Toronto's older neighbourhoods - Leslieville, The Beaches, Riverdale, High Park - where crane access is impossible and lumber is hand-carried through narrow side yards. Our experience with constrained sites keeps your project on schedule.

You provide architectural and structural drawings. We review framing requirements, identify steel beam/column needs, and assess site access challenges.
Typical timeline: 1-2 daysWe visit the property to assess access routes, staging areas, and any site-specific challenges. For laneway suites, we plan material delivery logistics.
Typical timeline: 1-2 hoursYou receive itemized pricing for framing, insulation, and drywall with timeline and scope clearly defined. No hidden fees.
Typical timeline: 3-5 business daysOnce foundation is ready and passed inspection, we frame floors, walls, and roof. Blocking installed for electrical, plumbing, and fixtures. Structure ready for mechanical rough-in.
Typical timeline: 2-4 weeksAfter mechanical/electrical rough-in and inspection, we install specified insulation - spray foam, batt, or combination per your drawings and energy requirements.
Typical timeline: 3-7 daysDrywall hung, taped, and finished to Level 4 (or Level 5 if specified). Walls ready for primer and paint. Final cleanup of our work areas.
Typical timeline: 1-2 weeksComplete garden suite construction in Toronto typically costs $250,000-$450,000+ depending on size, finishes, and site conditions. For our scope specifically: framing labor runs $15-$20 per square foot ($9,000-$12,000 for a typical suite), insulation adds $3-$8 per square foot, and drywall adds $4-$8 per square foot. So our complete framing-insulation-drywall package for a 600 sq ft garden suite typically runs $15,000-$25,000. The remaining costs cover design, permits, foundation, mechanical/electrical/plumbing, roofing, siding, and finishing.
Yes, Toronto legalized garden suites city-wide in February 2022. They're permitted on most residential properties that aren't on a public laneway (those would be laneway suites). Key requirements include maximum height of 6m (one storey) or 7.5m (two storey), setbacks from property lines, and maximum floor area based on lot size. You'll need building permits and must meet Ontario Building Code requirements for dwelling units. Check the City of Toronto's garden suite page for current rules.
We specialize in the structural trades: framing, insulation, and drywall. We don't handle design, permits, foundation, roofing, siding, windows, mechanical, electrical, plumbing, or finishing. You'll need a general contractor or separate trades for those scopes. Many GCs hire us specifically for the framing-insulation-drywall package, and homeowner-builders hire us directly when managing their own projects.
Garden suites and laneway suites are both detached backyard dwellings, but they're governed by different Toronto bylaws. Laneway suites face a public laneway and have been permitted since 2018. Garden suites don't require laneway access and were legalized in 2022 - they can be built on any qualifying residential lot. Structurally, framing requirements are similar and depend on the specific design, not the name.
Framing a typical garden suite takes 2-4 weeks depending on size and complexity. Two-storey designs and complex roof lines take longer. After framing, add 1-2 weeks for insulation (after mechanical/electrical rough-in) and 1-2 weeks for drywall. Our complete scope typically takes 4-8 weeks from foundation to paint-ready walls. Overall garden suite construction usually takes 6-12 months including design, permits, and all trades.
Yes, many Toronto homeowners act as their own GC to save 15-25% on overall costs. You'll need to manage permits, hire individual trades, coordinate scheduling, and handle inspections. We work directly with homeowner-builders regularly - you hire us for framing, insulation, and drywall, then coordinate your other trades around our schedule. It requires more of your time but can significantly reduce costs.
Yes, we specialize in constrained sites. We've framed laneway houses throughout Toronto's older neighbourhoods where there's no crane access and materials must be hand-carried through narrow side yards. Our crews are experienced with the logistics of tight spaces - staging materials efficiently, working in confined areas, and keeping projects on schedule despite access challenges.
