A Sag Harbor property on a narrow peninsula is designed to adapt to environmental conditions, creating unique experiences that change with the seasons.
Inspired by the great landscape tradition of his native Ireland, Declan Blackmore established Summerhill Landscapes in 1993. Built on a philosophy of applying the lessons of high level horticultural education to the execution of work in the field, the Summerhill team is a true collective, with over 350 years of field experience and 100 years of college level education directly related to the study of horticulture. The firm’s passion is to build and maintain extraordinary gardens, and it does so with an ardent sensibility, deep experience, and a love of the land. The foundation that Summerhill is built on is one of a never ending pursuit of knowing, understanding, and practicing fine horticulture. It is a mission that carries through our whole team, from the interns who arrive seeking to apply the lessons they have learned in the classroom, to the management group that constantly evaluates and refines our processes.
