Home office renovation is one of the most common project types in the GTA following the work-from-home shift. This thread covers all options for 2026.
Converting an Existing Room
Basic (paint, flooring, lighting, built-in desk): $5,000-$15,000. Full conversion with soundproofing, custom millwork, HVAC zoning, dedicated circuits: $20,000-$45,000. Mass-loaded vinyl + acoustic drywall for soundproofing: $8-$15/sq ft of wall.
Garage and Basement Conversions
Attached garage to home office: $40,000-$90,000 (insulation, heating, electrical, flooring, HVAC). Basement office conversion: $30,000-$60,000. Both require building and electrical permits.
Garden Suite as Office
Office-only detached garden suite (no full kitchen/bath): $80,000-$180,000. Separate hydro meter and fibre/cable internet are standard. Less than a full residential suite but still requires building permit.
What Buyers Look For in Home Offices (2026)
Dedicated separate entrance or isolated from main living space. Minimum 100 sq ft. Dedicated electrical circuits. Reliable high-speed internet infrastructure. Natural light.
