In the heart of Summerhill, surrounded by quiet residential streets and two of Toronto's most scenic ravines, is 21 Shaftesbury Avenue.

It's a mid-rise building with a warm facade of red brick and stucco, surrounded by small trees and landscaped shrubbery. 

It's pretty modest for the absolute splendor that lies inside. 

The four-storey condo building foyer. 

The foyer of the building sets the tone with a four-storey ceiling, blue and white tiled floors, and a grand piano to boot.

The lap pool. 

The building also features some stellar amenities as well, including a gym and exercise room, a pool, a large party room and separate conference room and library, as well as parking for visitors and residents.

The foyer of the condo. 

But none of that compares to the exceptional penthouse apartment that overlooks the Rosedale treetops. 

The hallway.

"[The condo] was completely rebuilt two years ago under the careful watch of architect Paul Roth," said realtor Paul Maranger. 

The family room with built-in bookcases and a fireplace. 

Roth was the same architect who renovated and restored 10 Toronto Street, which was the Old Toronto Post Office that is now home to Morgan Meighen & Associates.

The kitchen with tons of storage and a large centre island. 

The penthouse was also decorated and designed by Murray Oliver, who was involved in the restoration of the Old Mill Inn, and Anne Swain.

The study. 

The result is an exceptional 4,212-square-foot residence, with classic architectural elements, elegant designs and completely luxurious living. 

The living room with a fireplace and hardwood floors. 

The foyer opens up directly into a large living room with floor-to-ceiling windows, a cozy fireplace and columns that add to the opulence of the space. 

The dining room with hardwood floors, crown moulding and a walk-out to the terrace. 

The dining room flows into the breakfast room and family room.

The kitchen is open concept with the family room area, which is ideal for everyday living. 

One of the bedrooms. 

The bedrooms are separated from the common principal rooms in the condo, adding an extra sence of privacy.

The condo boasts three bedrooms and four bathrooms.

The connecting terraces with sweeping views. 

As for outdoor space there's 80 feet of indoor and outdoor connecting terraces. 

One of two terraces overlooking the trees. 

"The outdoor space is sensational: each of the two terraces is approximately 120 square feet each," notes Maranger. 

Gardens nearby. 

And if the terraces aren't to your liking there's plenty of green space nearby with five parks within one kilometer of condo, including the enormous David. A Balfour Park, Ramsden Park and Rosedale Valley.

A common outdoor area. 

The condo is listed for $7,800,000.
