What this listing tells us
Some homes are ready to move into. This one is ready to be reimagined.Set on a rare half-acre lot in South Ajax, steps from the waterfront trail and Lake Ontario, 17 Ontoto is a custom 1980s build with the kind of bones that stop you mid-tour. Soaring cathedral ceilings. A floor-to-ceiling fireplace in the main living area that commands the room. A double sided wood-burning fireplace And an extraordinary glass solarium with wall-to-ceiling windows on three sides, overlooking a lush, private garden, the kind of space people spend years trying to add to a house.The primary suite has its own cedar-clad ceiling, a private walk-out to the upper deck, and a dressing area that tells you the person who designed this home was thinking carefully about how they wanted to live in it.The location is genuinely hard to find. South Ajax, waterfront community, mature trees, half an acre, double garage. The waterfront trail is a short walk. The lake is right there. And so is proximity to local amenities.What it needs: your vision. Updated kitchen, refreshed baths, and a new coat of imagination over forty years of good craftsmanship. This is not a home for someone who wants everything done. It's a home for someone who can see what it's going to be, and who understands that the best ones always ask something of you first.The lot alone is worth the conversation.Inside: Double-height foyer with custom tile Cathedral ceilings Double sided fireplace Glass solarium Primary with walk-out deck Double car garage Hardwood floors and an immense amount of love in these walls.Outside: acre Private rear yard Mature gardens Steps to the waterfront trail South Ajax lakeside community and close enough to Amenities that you won't be giving anything up.
