Home Additions in Toronto & Grey County
When you love your location but need more space, a home addition is often the perfect solution. Odin Agnuk specializes in seamless home additions that expand your living space while maintaining your home's architectural integrity. Our additions blend so naturally they look like they were always part of the original structure.
With over 20 years experience in Toronto and Grey County, we design and build additions that maximize space, natural light, and functionality while complementing your home's existing design. From second-story additions to rear extensions, we handle every aspect from permits through completion.
Types of Home Additions
Second-Story Additions: Add bedrooms, bathrooms, or family rooms above existing space. Ideal for maximizing small urban lots. Requires structural engineering, roof removal and rebuild, stair integration, and foundation verification.
Rear Extensions: Expand kitchens, dining rooms, or living spaces. Most common addition type. Often includes new windows/doors, foundation work, roof integration, and interior finishing.
Side Additions: Add space laterally when lot width permits. Consider setback requirements, neighbour proximity, and window placement.
Sunrooms & Four-Season Rooms: Glass-heavy additions maximizing light. Options include three-season (unheated), four-season (heated/cooled), or conservatory-style designs.
Garage Additions: Single or double garages with optional living space above. Popular for creating rental suites, in-law apartments, or home offices.
Mudroom & Entryway Additions: Small but impactful additions improving functionality. Perfect for adding storage, organization, and transition space.

Heritage Considerations: Some Toronto neighbourhoods have heritage guidelines. We design additions respecting character while meeting modern needs.
Zoning Navigation: Toronto's zoning is complex. We research requirements, apply for variances when needed, and guide you through Committee of Adjustment if required.
Investment & Timeline
Cost Factors: Size, complexity, foundation requirements, matching existing finishes, systems integration (HVAC, electrical, plumbing).
Timeline: 6-12 months total (2-3 months design/permits, 4-9 months construction)
Frequently Asked Questions
Will I need to move out during construction?
Rarely. Most additions can be built with you in residence. We seal off work areas, maintain access to your home, and minimize disruption.
How do you match existing finishes?
We carefully match brick, siding, and roofing materials. Some aged materials are impossible to match perfectly—we discuss options for complementary or accent treatments.
What about property line setbacks?
We research all setback requirements before design. If variances are needed, we help prepare applications and represent you at hearings.
Can additions be built in winter?
Yes, with proper precautions. Winter construction has different challenges but is absolutely feasible with experienced builders.
