1 Marlborough is a refined boutique condominium located at 1140 Yonge Street, positioned between Toronto’s highly coveted Rosedale and Summerhill neighbourhoods. Thoughtfully developed by Devron Developments alongside Dorsay Development Corporation, this intimate residence rises approximately 10 storeys and features only 58 exclusive suites, emphasizing privacy, scale, and architectural integrity.

The project carefully blends heritage restoration with contemporary luxury, preserving the historic Pierce-Arrow showroom façade while introducing a modern residential form defined by elegant proportions and timeless materials. Residences are generously sized, primarily offering expansive two-, three-, and four-bedroom homes, along with a limited collection of multi-level penthouses designed for refined urban living.

At street level, the building enhances the public realm with a restored arcade along Yonge Street, a quiet patio on Marlborough Avenue, and a small collection of townhomes that create a seamless transition into the surrounding residential streetscape. With suite sizes starting at approximately 1,800 square feet, 1 Marlborough is tailored for discerning buyers seeking large-format living in a prestigious, transit-connected Toronto location.
