About this Property
Architecturally relevant and thoughtfully reimagined, 105 Marsdale Drive is an inspiring mid-century modern "Butterfly Roof" bungalow, offering nearly 3,000 sq ft of main-level living in one of South St. Catharines' most highly sought-after neighbourhoods. Originally designed in 1958 by Massey Award-winning architect James E. Secord, with a later addition influenced by renowned architect Ron Thom, this home blends preserved architectural character with modern updates. Features include floor-to-ceiling glass, clean horizontal lines, custom rosewood built-ins, and four fireplaces (3 wood-burning, 1 gas). The open-concept layout flows seamlessly through the living, dining, and kitchen areas, creating an ideal space for both everyday living and entertaining. The private backyard oasis is a standout feature, professionally landscaped and designed for resort-style living. Highlights include a Swenker concrete pool, hot tub, outdoor BBQ kitchen, pool change room, low-voltage landscape lighting, and a programmable in-ground sprinkler system. The fully finished lower level offers a self-contained suite with a separate entrance, two bedrooms, a full kitchen, spacious living areas, and a full bathroom - ideal for multigenerational living, growing teenagers, guests, or a nanny/in-law setup. Additional features include an original indoor cedar-lined sauna with shower, extensive storage, cedar-lined closets, and mature award-winning landscaped gardens providing exceptional privacy. This year, the home was recognized by the Niagara Architectural Society, celebrating its architectural history and significance. Located just steps from the Niagara Escarpment, Bruce Trail, Ridley College, the Pen Centre, and some of Niagara's top wineries and Michelin star restaurants. A rare opportunity to own an architecturally significant mid-century modern home with exceptional lifestyle flexibility in a prime location.
