With interest in Downtown living sky high these days, those selling luxury homes at Summerset at Frick Park in Squirrel Hill don't want buyers to forget about them.

As the developer prepares to embark on a major expansion of the housing development, it is cranking up the marketing as well, distributing sleek brochures in regional editions of The New York Times, in the Pittsburgh Post-Gazette and in other newspapers, touting the benefits of Summerset living.

Craig A. Dunham, principal in the Rubinoff Co., managing general partner of the development team, said officials launched the new marketing campaign to counter suburban competition and to remind potential buyers that city living doesn't necessarily mean Downtown.

"We live in a challenging marketplace. It's not the influx that Scottsdale [Ariz.] and some other places are experiencing. So you have to make sure that all the opportunities are made available in the marketplace," he said.

The campaign comes as Rubinoff and its partners get ready to launch a major expansion of the development, built on top of an old slag dump overlooking Nine Mile Run.

Summerset Land Development Associates, the partnership formed to undertake Summerset, received approval last week from the city's Urban Redevelopment Authority, which owns the land, to begin the work.

The second phase will involve the construction of 287 units in all, including 50 townhouses, 20 condominiums, 34 "cottage" homes, 67 "village" homes, and eight estate homes. The cottage homes are the smallest, at roughly 1,800 to 2,400 square feet, and the estates the largest, at roughly 3,500 to 6,500 square feet.

Also planned are 108 to 110 rental apartments, a 100- to 150-room hotel, and a 50- to 75-room senior assisted living center. There also may be a small bank attached to the hotel.

The entire second phase is expected to take four years from start to completion. It will stretch from the Summerset community center to Browns Hill Road. Summerset Land Development hopes to begin building the first of the new units in late winter or spring.

Mr. Dunham said one of the reasons the developer decided to do the marketing campaign was to correct an impression that Summerset "was sold out." While phase one is close to selling out, with only 25 Crescent Court condominiums remaining, the developer wanted to remind people that additional houses would be built.

The new phase will be getting started just about the same time as the residential building Downtown moves into full gear. That's another reason Mr. Dunham wanted to get the word out about Summerset.

"I don't think that the person that decides to live in the Crescent Court condominium, a two-story building nestled and surrounded by trees, is the same person that's wanting to live in a high-rise Downtown. So you have to make sure you're getting as much messaging out there as possible," he said.

The first phase featured 125 houses, 40 apartments and about three dozen condos. About 75 percent of those living at Summerset relocated from other sections of the city. Another 10 percent came from the suburbs and 12 percent to 15 percent moved from outside the region. The housing, officials said, has become particularly attractive to those working in the hospitals and universities in Oakland.

Mr. Dunham said Summerset is planning additional advertising this summer to market the Crescent Court condos. That will be followed by a campaign announcing phase two of the development.
