The attention to detail is incredible. The Andare team has just finished building my home and I'm absolutely blown away. I've been living in here for just under a month now and I still haven't found a single flaw, you can really see their experience and craftsmanship in every part of the home.

Local Context
Home Additions in Thornhill
What a home addition includes
An addition can involve foundation and footing work, framing, structural openings, exterior envelope, roofline integration, window placement, masonry or siding match, electrical, plumbing, HVAC extension, insulation, drywall, flooring, trim, and final finishing.
Andare coordinates those pieces as one build, not a series of disconnected trades. The new footprint has to support the way the family lives while still respecting the original house.
Design before the footprint is fixed
The in-house design team studies how the addition changes circulation, light, storage, furniture placement, views to the yard, and the relationship between old and new rooms. That work keeps the addition from becoming oversized, under-lit, or awkwardly connected.
For older Toronto homes, the design stage often has to account for narrow lots, neighbouring walls, mature trees, existing brick, older foundations, and service routes that were never planned for modern open living.
Structure, permits, and consultant coordination
Additions usually need permit drawings and structural input. Andare brings the required architects, engineers, and permit professionals into the planning so beam locations, wall openings, footings, drainage, rooflines, and exterior details are resolved before site work begins.
Process
- Site review and addition goals
- Layout and design direction
- Structural review and permit planning
- Construction scope and schedule
- Foundation, framing, envelope, services, and finishes
- Final walkthrough and handover

Home Additions in Thornhill: what shapes the work
Thornhill spans established Vaughan and Markham residential areas with older village character, mature subdivisions, ravine influence, larger family homes, townhouses, and infill or renovation demand. This layer should be used with the correct municipal slug and approval path. Common work includes kitchens, bathrooms, basements, additions, custom-home planning, exterior upgrades, in-law layouts, structural changes, and family-space improvements.
Thornhill is not a Toronto page. Depending on the property, local review may sit with Vaughan or Markham. Toronto suite, laneway, garden-suite, and multiplex assumptions should not be used unless the project is actually in Toronto.
Thornhill projects often involve mature lots, older house conditions, ravine influence, and larger family needs. Design-build helps compare renovation, addition, basement, and custom-home paths before the scope is fixed.
For Thornhill homeowners, Andare's design team can connect layout, family-space goals, finishes, storage, exterior changes, and consultant input before the project moves toward municipal review.
Andare supports Thornhill homeowners across Vaughan-side and Markham-side residential areas, including mature-lot streets, family subdivisions, ravine-influenced properties, and townhouse pockets. Andare keeps home additions tied to the home in front of us, not a generic city-wide template.
