Andare did an amazing job renovating my house, they turned an old and boring basement into a modern and exciting place. Their attention to detail was astounding and I couldn't be happier with the results.

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 Oshawa
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 Oshawa: what shapes the work
Oshawa includes older central homes, post-war houses, bungalows, newer north-end subdivisions, townhouses, lake-area properties, and family neighbourhoods tied to the city's industrial and commuter history. Common work includes kitchens, bathrooms, basements, additions, legal-suite review, structural updates, garages, and outdoor living.
Oshawa projects need City of Oshawa and Durham Region review. Toronto rules do not apply. Zoning, parking, grading, servicing, conservation, fire separation, ceiling height, tree impacts, and building permits can affect suites, additions, and major renovations.
Oshawa work often focuses on getting durable value from existing homes: better lower levels, stronger layouts, updated kitchens, added space, and repairs or structural changes that make older houses work for current households.
Andare can help Oshawa homeowners decide what to improve first, how rooms should connect, what finishes make sense, and where structure or permits need consultant review.
Andare supports homeowners in Central Oshawa, O'Neill, McLaughlin, Eastdale, Taunton, Northglen, Lakeview, Kedron, Windfields, and surrounding family neighbourhoods. Andare keeps home additions tied to the home in front of us, not a generic city-wide template.
