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
Duplex Conversions in Richmond Hill
What a duplex conversion involves
A duplex conversion may include separate entrances, a second kitchen, bathroom planning, fire and sound separation, egress, electrical and plumbing upgrades, HVAC strategy, suite layouts, storage, waterproofing review, and permit coordination.
The project has to work for both households, not only pass as extra square footage.
Design for two real homes
The design team plans privacy, circulation, storage, natural light, kitchen function, bathroom placement, and durable finishes. Each unit needs a clear identity and a layout that does not feel compromised.
Many Toronto houses can support two-unit living, but feasibility depends on structure, access, ceiling height, windows, services, and municipal review.
Consultant and permit coordination
Duplex conversions often require drawings, code review, and permit coordination. Andare keeps that technical review close to the suite layout so the plan can be built with fewer surprises.
What Andare clients say
We needed more space, so Andare helped us expand while renovating the entire home.
Our home renovation exceeded all expectations. Andare added space, improved the layout, and modernized every detail.

Duplex Conversions in Richmond Hill: what shapes the work
Richmond Hill includes older village-core streets, established family subdivisions, large detached homes, townhouses, condos, ravine and moraine-influenced areas, and communities such as Mill Pond, Bayview Hill, Oak Ridges, Langstaff, Rouge Woods, and Observatory. Common work includes custom homes, additions, basements, kitchens, bathrooms, family-room changes, accessibility upgrades, drainage-aware work, outdoor living, and storage improvements.
Richmond Hill is outside Toronto. Projects need local zoning, permit, grading, tree, conservation, servicing, parking, fire separation, and building-code review. Toronto-specific additional-unit or multiplex wording should not be copied here.
Richmond Hill projects often involve larger family homes, moraine or ravine context, mature streets, and growth-area planning. Drainage, grading, trees, access, and layout can all shape the project before finishes are chosen.
For Richmond Hill homes, Andare's design team can connect room planning, lower-level use, accessibility, kitchen capacity, materials, exterior fit, and consultant input before permits and trades move ahead.
Andare supports Richmond Hill homeowners in Mill Pond, Bayview Hill, Oak Ridges, Crosby, Langstaff, Observatory, Rouge Woods, Jefferson, and nearby family neighbourhoods. Andare keeps duplex conversions tied to the home in front of us, not a generic city-wide template.
