Beyond a discreet tree-lined street in the heart of prestigious Old Glenridge lies one of Niagara's most extraordinary private estates - a rare offering where timeless elegance, architectural character, and breathtaking natural surroundings exist in perfect harmony. Set on 2 acres overlooking the serene 12 Mile Creek ravine, this landmark residence presents an exceptional lifestyle defined by privacy, sophistication, and understated luxury. Moments from Ridley College, downtown St. Catharines, fine dining, golf, vineyards, and the Niagara Escarpment, the estate offers the rare privilege of secluded resort-style living within the city. The home masterfully balances historic charm with refined contemporary design and an uncompromising attention to detail - from rich white oak flooring and bespoke millwork to designer lighting, elegant fireplaces, and expansive windows framing tranquil ravine vistas. Principal rooms are both grand and intimate, designed for entertaining as well as relaxed everyday living. Chef's kitchen at the heart of the home, seamlessly connects to elegant gathering spaces and outdoor terraces, creating a natural flow between indoor and outdoor living. The grounds are nothing short of spectacular - an enchanting private sanctuary featuring mature canopy trees, manicured gardens, winding pathways, and panoramic views over protected natural landscape. A heated inground pool and multiple outdoor entertaining areas evoke the atmosphere of an exclusive countryside retreat. Adding to the estate's remarkable versatility is a beautifully appointed carriage house suite above the heated four-car garage, ideal for guests, multigenerational living, executive office space, wellness studio, or private retreat. Rarely does a property of this calibre become available in Niagara - where architectural significance, substantial land, luxury amenities, and an irreplaceable ravine setting converge so effortlessly. More than a residence, this is a legacy estate.
Written by the listing brokerage to sell the house. Nothing in it is verified, so take its claims about condition to an inspection, not from it.
The pills are copied from the listing and sorted for reading, with nothing added to them, and a group the listing did not fill in is absent rather than empty. Where a group is written as sentences instead, those are ours: what the listing named, and what it means.
On the record, and not one of the groups above.

None of this is PropTx data. Each figure is our own and carries its source: the true cost to own, the mortgage studio, the inspection plan, and the rest.
20% is the legal minimum on this price.
20% down · 4.68% indicative 5-yr fixed · The number of years the whole balance is paid off over. A longer amortization lowers the monthly payment and raises the total interest.. $11,180 for 2025, from the tax figure stated on the listing, divided by twelve. That is what the current owner pays, as the listing states it. That twelfth is the annual amount levelled across the year and not a payment you will make on any date. How a municipality actually collects it is set out in documents nobody here has read.; heat and utilities estimated. Figures illustrative.
Compare lenders and private optionsIt asks one question first: whether someone is already acting for you. That answer changes who books the visit and who is on your side inside the house.

The listing does not say whether there is a second dwelling unit here. Other records in this set state it either way, so this is a silence rather than a no.

Two figures stand against this house for two different purposes, the asking price and the assessment, so they do not agree and were never meant to. The gap is worked out here rather than left for you to hold in your head.
Nothing of this kind on the record, and nothing here fills it in from an average of other houses.
The figure property tax is apportioned from, valued as of a date that is not today. It is not a market value and no lender treats it as one.

None of these is an appraisal. Your lender orders one of those once an offer is accepted, and it is the figure that decides how much they will actually lend.
At 20% down and 4.68% fixed, the all-in monthly cost works out to $14,836. Every line, the pool and the well included, plus the first-year total, is on the full breakdown.
