Once described as one of the top 100 houses in the world by architecture experts, a unique home in Springbank is for sale for the first time.

The nearly 5,000-square-foot luxury home, designed and owned by architect Marian Liptak, is listed for $2,668,880 and being sold through realtor Robbie O'Leary of MaxWell Westview Realty.

"It's only a few minutes from town but this is a peaceful, Zen environment -- very private," said O'Leary.

"It's all about the natural environment. Living with nature. Bringing nature into the house."

The energy-efficient, eco-friendly home, nestled between towering aspens, includes five bedrooms, 4 1/2 baths, a gym, a winemaking room, a huge entertaining atrium, a large rear patio with six-person hot tub, a home office with a separate entrance, a three-car garage, an elevator to all three floors, in-floor heating, steel tile roof, lots of natural light and high ceilings.

Nearly two years ago, World Architecture News highlighted the home, at Spring Willow Place S.W., for its unique style.

"The house is comprised of three architectural components: an A-frame glass structure in front, a "cube" in the middle, and an open, A-frame structure over the rear patio," said World Architecture News in 2008.

"The nature of Calgary's climate challenged the architect to design 'real living' space that can be enjoyed throughout the year. The front of the house was designed to create a pleasant, invitational living-entertainment area with views of existing natural beauty while creating a sense of connection with neighbours.
