The Initiative for Public Art Reston formally dedicated sculptor Patrick Dougherty’s public art installation at Reston Town Center’s Town Square Park on Saturday.

North Carolina-based Dougherty and a crew spent two weeks constructing the building-sized artwork out of saplings.

The work is already a kid favorite. On Sunday, groups of youngsters played hide-and-seek and chased each other through the adjoining structures. They peered from the “windows,” which give the structure an overall fairy tale cottage in the woods feeling.

The art work will remain on site for at least a year, IPAR says.
