Overview· 81 Mackenzie King Avenue St. Catharines

MLS® #X13867180

Sophistication and modern engineering converge at 81 Mackenzie King, an architectural masterpiece where uncompromising custom luxury meets a brilliant contemporary design. Passing the sleek front porch, you are greeted by a grand foyer that sets an immediate impression of style and scale. Grounded by beautiful premium flooring, the open-concept main floor delivers an incredibly airy feel, seamlessly uniting the expansive living and dining with a high-end chef's kitchen centered around a massive island, premium integrated panelled appliances, and two custom walk-in pantries. This level features a main-floor laundry room and a sophisticated powder room. A striking staircase with sleek glass railing guides you upstairs to a very spacious loft area. This level hosts a large primary retreat defining opulence with his-and-hers closets and a spa-like ensuite with a separate bathtub and a standalone shower. The wide, sun-drenched hallway leads you to an exclusive private balcony, alongside two other generous bedrooms equipped with built-in closets and a second full bath. True luxury extends below to the impressive walk-out basement with an open-concept living/dining area, a full-size kitchenette, a second laundry, and two large bedrooms joined by a full Jack-and-Jill bathroom. The lower level showcases polished concrete floors equipped with energy-efficient radiant in-floor heating-a hidden mechanical comfort that also extends into the insulated garage. Two oversized glass patio doors off the dining areas on both levels create flawless transitions to the exterior living spaces, leading from the main deck and lower patio out to a pristine, fully fenced backyard oasis bordered by mature privacy greens. Complete with premium German tilt-and-turn windows featured throughout, a 6-car concrete driveway, a fully owned tankless hot water system, and a separate side entrance into the grade-level walk-out, this home provides an unmatched, turnkey lifestyle.
