Despite the toxic mould, peeling ceilings, and animal excrement, a large mansion sitting on an expansive piece of property on Toronto鈥檚 waterfront has sold for a whopping $3.45 million.

The dilapidated 13,000 square-foot home at 4 Birchmount Rd. in Scarborough made headlines last spring when it was put on the market with an asking price of $3.8 million.

Normand Gautreau, a Royal LePage realtor who wasn鈥檛 involved in the final sale but showed potential buyers the property at the time, said he and his partner toured the house during an agents鈥 open house in early June.

鈥淲e had to put masks on our faces because of the mould,鈥 he recalled to CTVNews.ca during a telephone interview on Tuesday. 鈥淭here were no handrails. It was really, really scary.鈥

The real estate agent said he even had to sign a disclaimer before entering the crumbling mansion because it was so dangerous.

shows the inside of the main floor of the home with broken cabinetry, water damage on the ceilings, and scattered debris everywhere.

In spite of its unsightly appearance, the five-bedroom, seven-bathroom house was sold under a receivership shortly after it was put up for sale.

Gautreau said the speedy sale can be credited to the property鈥檚 impressive 135 feet by 548 feet lot, which boasts a 鈥180-degree view鈥 overlooking Lake Ontario, according to the listing.

鈥淚t鈥檚 basically land value,鈥 he said.

The realtor predicts the new buyer will either tear down the structure and build an entirely new house in its place or strip it down so just the skeletal steel beams remain and renovate from there.

鈥淚t鈥檚 a massive undertaking,鈥 he said. 鈥淚t鈥檚 13,000 square feet. If you just calculate the plumbing, and drywall, and hardwood floors and times that by the square footage鈥 just the materials is massive and then you have the labour.鈥

By Gautreau鈥檚 estimation, however, the costly construction will be worth it in the long run. He said the new owner should be able to fetch $8 million to $10 million for the property after it鈥檚 been fixed up 鈥 depending on the market at the time, of course.

鈥淎t $3.45 million, it really is pretty good,鈥 he said. 鈥淚t鈥檚 land value. I think it鈥檚 a good deal.鈥

A 鈥榙ream home鈥

Before the sprawling mansion on Birchmount Road fell into disrepair, Gautreau said it was actually a 鈥渄ream home鈥 for former owners Lauren and Christine Drotos.

The couple purchased the original century-old farmhouse on the property for $1.9 million in 2006 and set about renovating the structure from top to bottom. The couple redid the interior and even started putting in a basement basketball court complete with 20-foot high ceilings.

Even though local zoning laws prohibited anything larger than a two-car garage, Gautreau said the Drotos were able to side-step that rule by installing a garage with only two doors, but that could fit up to 16 vehicles.

鈥淚t鈥檚 such a unique property,鈥 he said. 鈥淚t鈥檚 really a crazy spot.鈥

When the cost of renovations became too much, the couple attempted to sell the partially constructed home for nearly $6 million in 2012, but it never sold.

Eventually, the Drotos gave up the property and it was seized by creditors.

Now, after nearly 10 years of sitting abandoned 鈥 save for the occasional rodent or trespasser 鈥 the incomplete home at 4 Birchmount Road finally has a new owner.

Gautreau said the sale has been tangled up in the courts since the offer was accepted in June because the receiver has had to sort out payments to all of the various lenders on the property over the years.

Although it鈥檚 not known what the new owner will do to the property, Gautreau said some of his clients who live in the area are pleased to know that something will happen to it.

鈥淭hey鈥檙e thrilled,鈥 he said. 鈥淭hey鈥檙e saying it鈥檚 been such an eyesore for such a long time and they鈥檙e really, really happy there鈥檚 a new owner. Hopefully this person has deep enough pockets to do a decent job with it.鈥
