Valley House, designed by acclaimed architecture studio Superkül and built by Derek Nicholson Construction, is a striking expression of minimalist contemporary design, where sculptural form, natural materials and the surrounding landscape are brought together in complete harmony. Situated on an extraordinary 75x164 ft (plus an additional 81x173 ft lot at rear) reverse ravine lot in Hogg's Hollow, the residence is enveloped by mature trees & expansive views. Defined by clean lines & a warm palette of walnut, teak, porcelain, glass & stone, the architecture creates a seamless dialogue between interior & exterior. The main level unfolds through a series of beautifully balanced spaces, from the sunken family room with custom teak cabinetry, grasscloth wallpaper & cherry-wood ceiling to the chef's kitchen with bespoke Bulthaup cabinetry, Gaggenau appliances, Caesarstone surfaces & seamless access to the rear terrace & gardens beyond. The principal living space is anchored by a dramatic double-sided wood-burning fireplace & framed by floor-to-ceiling glass overlooking the ravine. The primary suite offers panoramic views, custom dressing room cabinetry & a spa-inspired ensuite overlooking the open-air courtyard. Upstairs, 3 additional bedrooms feature generous proportions, custom closets with integrated organizers & warm walnut flooring. A private lounge & study create an intimate retreat above the main living spaces, featuring custom banquette seating, a dedicated workspace & access to a private terrace overlooking the ravine landscape. The lower-level extends the residence with expansive above-grade windows, flexible media & fitness spaces, guest accommodations & carefully considered utility spaces. Valley House is a sophisticated expression of modern architecture where simplicity becomes the ultimate ultimate luxury.

Listed at $7,298,000. Going by how homes in Bridle Path-Sunnybrook-York Mills and the wider GTA have actually closed against their asking prices (about 97%, 8 local closings in 90 days), the likely sale price is near $7.08M, if it sells. A realistic range is $6.63M to $7.98M.
Independent value check: no figure for this home. Going only by the sales record, our model lands more than 25% below the ask. At that distance an automated figure has rarely been close to the eventual sale price, so we are not printing one. The usual reason is something the record cannot show: a rebuild, a second unit, or a lot or setting unlike the homes around it.
Longer on the market than typical. 70 days on the market against about 44 for homes like it here, and asking 45% above where comparable closings put it.
Total price vs nearby homes. Likely closing about $7.08M, from 8 recent closings in this pocket.
The market behind the math:
About 13.1 months of inventory: 35 detached homes for sale in the area against 8 closings in the last 90 days. Under two months favours sellers, over four favours buyers.
Price per square foot: this home lists at $1,717/sqft against an area asking average of $1,821/sqft.
- Ravine / green setting. This home is described as backing onto a ravine or green setting. The ravine backing is priced into the comparison. How much it is really worth depends on whether the house sits on table land with the slope well behind it, or drops away right behind it, and that part is my in-person call.
How this estimate is builtthe short version
This figure comes from a model built on about 44,000 recent GTA sales. It weighs this home’s tax assessment, size, age, location and features against what homes like it actually sold for, including sales in this neighbourhood.
It never sees the asking price. The 8 most comparable recent sales on their own, adjusted for size, beds, baths and lot, point to about $5.59M. Condition and finishes remain an in-person call.
What the listing highlights2 points to weigh
Claims from the listing, worth confirming in person. I can book you a private showing.
- Ravine lot: privacy and premium value, but confirm the buildable area and any conservation limits. Worth verifying
- Upscale kitchen: a genuine value driver, verify the appliances, stone, and finishes in person. Value driver

Read this with carewhy it’s an estimate, not an appraisal
Priced above comparable homes overall, but the price per square foot ($1,717/sqft) is in line with the area, so you are paying for extra space rather than a premium.
The listing states size as a wide range, so the size adjustment is approximate and this estimate is a rough read. I can confirm exact square footage to tighten it.
There were not many closely comparable homes right in Bridle Path-Sunnybrook-York Mills, so I widened the search to the surrounding area.
