CHEVY CHASE is where young professional people in Dupont Circle and Capitol Hill rowhouses move when they have their second child.

The charm of Chevy Chase Village comes from those huge, 1900s houses that seem to wrap families in warm, expansive comfort. They're the sort of house that everyone with children dreams of having, because there's enough room, and enough land for everyone to have his own peace and quiet, no matter what war and noise are being waged by the other members of the family.

You know when you drive down those streets with the huge trees, the neat lawns and the fresh paint that the people inside have a floppy dog (maybe two) and at least the customary 2.5 children.

Washington is only a street away, but its problems seem as small as if seen through the wrong end of a telescope.

Chevy Chase doesn't feel like a suburb, because there's no long, dismal, bumper-to-bumper drive. The village atmosphere is very strong -- people take an intense interest in the community's betterment. The people are all prosperous, in good and usually interesting jobs. You can also guess they are probably lawyers, doctors or psychiatrists, because these houses are not now and never have been cheap.

Six of the more interesting houses in the area will be on view during the annual tour to benefit the Citizens Coordinating Committee on Friendship Heights. The houses include an 1896 frame Victorian with an Americana collection, a Tudor cottage, a late 19th-century farmhouse, a 1900 Georgian revival with art by Washington women artists and the Henry and Marjorie Zapruder house (see story above).

Tickets are $7 in advance, $8 the tour day, and include tea and a historical exhibit. Hours are noon to 5 p.m. Saturday, April 11. Reservations are available by calling 652-6910. Only on the day of the tour, tickets will be sold at the first house, 5906 Connecticut Ave. NW. Please expect to buy tickets there only on the day of the tour.
