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.

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.
