House of the Week: Architectural masterpiece in a prestigious lakeside neighbourhood in Oakville, listed by Sam McDadi Real Estate

Prestigious living abounds in Oakville’s lakefront Bronte neighbourhood, and even more luxury awaits inside this home at 152 Third Line, built by custom homes builder Investbuild. This estate is a masterpiece of architecture inside and out, with design elements that are sophisticated, functional, and beautifully executed.

Walk Thru + Tour
This newly built custom home is one of the most impressive properties to grace Oakville so far, effortlessly blending modern sophistication with timeless craftsmanship across all 5,500+ sq. ft of living space.

Strikingly sophisticated interiors

The first impression is made with the home’s exterior, where the striking limestone stucco is combined with clean lines and expansive windows to create elegant curb appeal.

Step inside to the grand foyer with breathtaking Taj Mahal marble flooring and brass inlay, leading into light-filled living spaces with 9″ white oak floors and a dramatic book-matched marble fireplace.

Beautiful design in every room

Comfortable living spaces with expansive windows

This home confirms that two kitchens are better than one, and both are equally remarkable. The show kitchen boasts elegant Sub-Zero and Wolf appliances and a large kitchen island, while the secondary chef’s kitchen features bespoke cabinetry, Taj Mahal marble counters, and matching backsplash.

Both kitchens are aesthetically pleasing and highly functional

A gorgeous solid oak staircase with glass railings and step lighting will take you to the upper and lower floors, as well as a private elevator for added convenience.
