Expert home addition framing services in Toronto. Structural framing for new builds and additions.
Planning a home addition in Toronto? Konstruction Group provides the framing, insulation, and drywall services that form the structural core of your expansion project. Whether you're a general contractor building additions for clients or a homeowner managing your own renovation with permits in hand, we deliver the trade work that transforms plans into reality. From second-storey pop-tops to rear kitchen extensions, our crews have framed hundreds of additions across the GTA - handling the complex tie-ins that make new construction blend seamlessly with existing homes.


If you're a GC taking on home addition projects, we can be your reliable framing subcontractor. Addition work is more complex than new construction - proper tie-ins, matching existing floor heights, temporary weather protection during roof removal. Our crews have the experience to handle these challenges without slowing down your project. We carry $10M liability insurance and full WSIB coverage, coordinate well with other trades, and show up when promised.
Many Toronto homeowners manage their own addition projects to control costs and quality. If you have your architectural drawings, engineering, and permits in place, we can handle the framing, insulation, and drywall - three major trades under one contract. You'll coordinate foundation, roofing, mechanical, electrical, and finishing trades. We're experienced working directly with homeowner-builders and can help coordinate the handoffs between our work and other trades.
The connection between your addition and existing home is the most critical part of the project. Poor tie-ins cause settling, cracks in drywall, and water infiltration problems. Our crews properly connect new floor systems to existing structure, match wall heights and roof lines, and ensure load paths transfer correctly. We follow your structural engineer's specifications for all connection details - this isn't the place to cut corners.
Adding a second storey is the most complex addition type. It involves removing your existing roof, building new floor and wall systems on top of existing walls, and constructing a new roof - all while protecting your home from weather. Your structural engineer must verify existing walls and foundation can support additional loads - often requiring steel beam or moment frame installation to handle increased loads. We coordinate temporary weather protection, execute the framing per engineered drawings, and work efficiently to minimize the time your home is exposed to elements.

You provide architectural and structural drawings. We review framing scope, tie-in details, steel requirements, and any complex connection points.
Typical timeline: 1-2 daysWe visit to assess the existing structure, access for material delivery, staging areas, and coordination requirements for occupied homes.
Typical timeline: 1-2 hoursItemized pricing for framing, insulation, and drywall with timeline and scope clearly defined. We identify any potential challenges upfront.
Typical timeline: 3-5 business daysWe coordinate start date with foundation completion and your project timeline. For second storeys, we plan weather protection logistics.
Typical timeline: 1-2 weeksComplete framing including tie-ins to existing structure, floor systems, walls, and roof. Steel beams/columns installed if specified. Blocking for all trades.
Typical timeline: 2-8 weeksAfter mechanical/electrical rough-in and inspection, we install insulation and complete drywall to Level 4 finish. Walls ready for painting.
Typical timeline: 2-4 weeksComplete home additions in Toronto typically cost $300-$600+ per square foot including all trades and finishes. For our scope specifically: framing labor costs $15-$20 per square foot ($7,500-$20,000 for a typical 500-1,000 sq ft addition), insulation adds $3-$8 per square foot, and drywall adds $4-$8 per square foot. Our complete framing-insulation-drywall package typically represents 15-25% of total addition cost.
Second storey additions in Toronto typically cost $350-$700+ per square foot for complete construction - higher than main-floor additions due to structural requirements and roof work. For our framing labor scope, expect $15-$20 per square foot. The complexity of removing the existing roof, building new floor and wall systems, and protecting the home from weather requires experienced crews.
A structural engineer must evaluate your existing foundation, walls, and overall structure. Many Toronto homes - especially those built with proper construction methods - can support second storeys. Some may need foundation reinforcement or wall upgrades. We execute the framing per your engineer's specifications but don't evaluate structural capacity ourselves. Your architect or GC typically coordinates the engineering.
Complete home additions typically take 4-8 months from permit to occupancy, depending on size and complexity. For our scope: main-floor additions take 2-4 weeks to frame plus 2-3 weeks for insulation and drywall. Second storey additions take 4-8 weeks to frame due to roof removal and reconstruction. Weather and coordination with other trades affects overall timeline.
No - we specialize in the structural trades: framing, insulation, and drywall. For a complete addition, you'll also need architects, engineers, permits, foundation work, roofing, siding, windows, mechanical (HVAC), electrical, plumbing, and finishing trades. Many GCs hire us specifically for the framing-insulation-drywall package. Homeowner-builders hire us directly and coordinate other trades themselves.
Usually yes for main-floor additions - the existing home remains intact during construction. Second storey additions require temporary roof removal, so you'll need to plan for weather protection and possibly temporary relocation during the most disruptive phase. We work efficiently to minimize exposure time, typically 1-2 weeks for the roof-off period.
Yes - all home additions in Toronto require building permits. You'll also likely need zoning approval depending on your lot coverage, setbacks, and the size of addition. Permit timelines vary but typically take 2-4 months. We frame to permitted drawings - permit acquisition is typically handled by your architect or GC.
