About 1 Marlborough
1 Marlborough is an upcoming collection of luxury condominium residences by Devron Developments, together with Dorsay Developments, at 1 Marlborough Avenue in Toronto’s Rosedale neighbourhood, at Yonge Street and Marlborough Avenue. Pricing, the suite mix and occupancy have not been published yet, so contact us for current pricing. The project is coming soon, and you can register with us for first access.
Location and neighbourhood
1 Marlborough sits on Yonge Street at Marlborough Avenue, in Rosedale, one of Toronto’s oldest and most established residential neighbourhoods. The site address is 1 Marlborough Ave, Toronto, ON M4W 2L5.
This stretch of Yonge Street is a walkable midtown corridor with shops, cafes, restaurants and everyday services. The TTC Line 1 subway runs under Yonge Street, so buyers can reach downtown Toronto and North York without a car. Drivers have access to the main midtown roads, and the Don Valley Parkway connects the east side of the city to the highway network.
Rosedale is known for its tree-lined streets, ravines and parks, and the area is close to Yorkville and the Bloor Street shopping district to the south. Ask us about the schools that serve the address; school boundaries can change and should be confirmed with the school board before you buy.
Compare 1 Marlborough with other pre-construction homes in Toronto.
Home types and features
1 Marlborough is planned as a boutique condominium of luxury residences rather than a large tower with hundreds of small units. The builder has not yet published floor plans, suite sizes, the number of suites, the height of the building or the amenity list.
Register with us and we will send you the floor plans, the features and finishes list and the amenity details as soon as they are released. Viewings are by appointment only, and we can help you arrange one.
Pricing and deposit structure
Prices and the deposit structure for 1 Marlborough have not been published. Contact us for current pricing before you plan your budget. Call Tall Property at 416-878-0749 and we will share pricing, the deposit schedule and availability as soon as the builder releases them.
Why buy here
- An established address: Rosedale is a mature, mostly low-rise neighbourhood where new condominium sites are rare.
- Transit on Yonge Street: the TTC Line 1 subway runs under Yonge, giving a car-free option for getting downtown or north.
- Boutique scale: the project is planned as a smaller collection of luxury residences, which suits buyers who are downsizing from a house or want a quieter building.
- Experienced developers: Devron Developments is also behind 101 Spadina Condos and South Station Condos in Toronto, and is partnering with Dorsay Developments on this project.
As with any pre-construction purchase, read the agreement of purchase and sale carefully, ask about closing costs and the occupancy timeline, and have a real estate lawyer review the contract during the cooling-off period.
