Model houses have been started in the [WORDS ILLEGIBLE] Harbor community went of Annapolis, where the D.C. [WORD ILLEGIBLE] of U.S. Home Corp. plans to [WORD ILLEGIBLE] promotions for an adult community this autumn.

Richard A. Sullivan, division president of the building firm, which is [WORD ILLEGIBLE] in Clearwater, Fla., said that the [WORD ILLEGIBLE] development site, which is [WORD ILLEGIBLE] by the South River, Broad [WORD ILLEGIBLE] and Rte. 59, will be developed over a 10-year period with 1,600 [WORD ILLEGIBLE] . Initial prices will range from [WORD ILLEGIBLE] to $75,000.

The age minimum for buyers, he said, will be 45. Six models, designed by Bucher & Meyers, will be shown.

Heritage Harbor, which was originally started in 1974 by Croyder-Irvin firm (then a division of Ervin-Atlantic and a subsidiary of American Cyanamid), is being promoted as an adult community because U.S. Home is convinced that there is a market for dwellings for mature persons and couples nearing retirement who plan to remain in this area.

The fewer than 50 families already living in the community will be allowed to join in community amenities, the firm said.

"We will build a $1.5-million clubhouse, a nine-hole golf course, tennis courts, nature trails and other recreation facilities that will be turned over to the homeowner association," said the 32-year-old Sullivan.A Washington native, he studied accounting at the University of Maryland and was the comptroller of the U.S. Home division here before succeeding founder Harness Perton as president last year. Perton founded Page Construction in 1962, said it to U.S. Home in 1971 and remained as president until last spring.

Some 63 semi-detached traditional houses were built and sold in Heritage Harbor by the original developer. Croyder-Irvin had hoped to get an access to Rte. 50 for the property that touches it, but failed.

Since 1962 the Page and U.S. Home firms have built nearly 2,000 dwellings in this area. Last year's total delivery of 240 houses for a total volume of $13 million is expected to increase to 350 houses and $20 million this year. With the opening of Heritage Harbor and several smaller subdivisions in the later part of this year the firm has a goal of 450 houses in 1979.

Currently, the D.C. division of U.S. Home is building traditional single-family houses in the $125,00O-up range in Wolf Trap Woods on Rte. 7, west of Tysons Corner and town houses and "four-plexes" priced around $50,000 range at Cinnamon Woods and North Creek near Germantown. It is also building "triplexes" in the mid-$40,000s at St. Charles in CharlesCounty, Md.
