Within the historic district of Windle Park in Tarrytown, an area distinguished by its Victorian structures, developers are constructing a condominium community that will blend in with the prevailing architectural style. The community, called Whisper Hill on the Hudson, is a 43-unit, two-family-house development set on a bluff north of the Tappan Zee Bridge.

THE Harts and Spoonhours share a tragedy. Each family had a teen-age son who took his own life. Now the two families are speaking out about their experiences with suicide, in the hope that the knowledge could prevent other teen-age deaths. Each year there are 5,000 to 6,000 suicides reported nationwide. The National Center for Health Statistics reports that in the 15- to 24-year-old group there were 4,700 suicides during 1983, the latest year for which it has figures. In the Westchester-Rockland-Putnam County area there has been a cluster of teen-age suicides, with 19 reported in the last 18 months. Last week an 18-year-old Mount Vernon girl, Christina Taylor, apparently committed suicide by jumping in front of a train, according to the police. ''There are a lot of people who don't have any awareness that the problem even exists, let alone at this magnitude,'' Anne Spoonhour said. To make parents aware of the warning signs of suicidal teen-agers, Representative Joseph J. DioGuardi introduced a bill that was approved in the House - similar legislation passed in the Senate - and President Reagan proclaimed June as Youth Suicide Prevention Month. Mary and Patrick Hart and Mrs. Spoonhour are scheduled to discuss their sons' deaths as part of a weeklong morning talk program on WVIP radio in Mount Kisco beginning Monday.

Returning anywhere after 46 years is hazardous. Even the most ordinary past sets psychological land mines for the present. Returning to Oz - that Technicolor world of dancing Munchkins over the rainbow, of ruby slippers and winged monkeys and the Wicked Witch of the West - is a booby trap of immense proportions. ''Return to Oz,'' the Walt Disney movie which opens June 21 in 1,300 theaters, including Radio City Music Hall in New York, must do more than compete with an old movie starring Judy Garland that is shown on television once a year. Since it was first shown on television in 1956, M-G-M's 1939 ''The Wizard of Oz'' has become an American artifact, a piece of pop culture as tangible as a pottery shard. Over the last 29 years, ''The Wizard of Oz'' has been seen in 436 million homes. ''Return to Oz'' is neither a remake of M-G-M's ''The Wizard of Oz'' nor - in Hollywood terms - a sequel to that movie. The Dorothy in ''Return to Oz'' is seven years younger than the Dorothy played by 16-year-old Judy Garland. The Scarecrow, the Tin Woodman, and the Cowardly Lion are, at best, peripheral characters. The Wizard does not appear at all. There are no Munchkins. Nor does Dorothy's dog Toto return to Oz. Most importantly, ''Return to Oz'' is not a musical.

The United States has reportedly sent a commando unit to the Mediterranean to be ready to storm the hijacked Trans World Airlines plane if deemed necessary. But American officials said today that they were counting on Algeria and the Red Cross to bring about a nonviolent resolution of the crisis. The officials, who would not confirm the dispatch of the so-called Delta commando unit from Fort Bragg, N.C., said all prudent measures were being taken, including military. Information on the movement of the unit came from other than American sources, but the whereabouts of the team was not disclosed. No Request from Algeria A similar move was made in December, when members from the Delta unit were dispatched to the Mediterranean in case an opportunity arose during the hijacking of a Kuwaiti airliner to Iran.

Tze-Chung Chen continued setting records with heroic shots and deadly putting today despite a steady, cold rain as the 26-year-old from Taiwan increased his lead to two strokes in the 85th United States Open. Andy North, the winner of the 1978 Open who has not won a tournament since, was in second place, with David Barr of Canada three shots farther back in third place. Chen, who led both the first and second rounds by a single shot, had his third straight sub-par round over the Oakland Hills Country Club course with one-under 69 for 7-under 203 for 54 holes, tying the 54-hole Open record set by George Burns in 1981 at Merion. David Graham won that Open as Burns tied for second.
