BUILT INTO A HILLSIDE on the grounds of a country cottage in New Canaan, this lovely potting shed is as functional as it is aesthetically pleasing. In addition to a potting room, the stone structure has two large greenhouses—a hothouse for over wintering tropical plants and a warmhouse for propagating annuals and perennials— both of which overlook a generously proportioned courtyard. The potting shed is accessed through an enclosed sunken entry garden which leads to an open air loggia. A stone staircase featuring a finely crafted wrought iron balustrade offers a dramatic ascent from the loggia to a second story apartment. Occupying the entire second floor, the apartment serves as the living quarters for the estate’s resident horticulturist, who oversees the maintenance of the property’s extensive gardens. The first story of the potting shed is constructed from Minnesota Kasota stone with carved limestone surrounds framing the doors and windows. The walls of the upper story are sheathed in the same English clay tiles that have been used for the steeply pitched roof. This mixture of exterior surface materials, combined with the use of oak wooden beams and posts for the interior, and rustic paneled doors throughout—so highly reminiscent of the English Arts and Crafts style—are but a few of the extraordinary details that infuse the potting shed with its distinctive flair.
