“For all its daring modernism, Grant Duncan’s home is built on a solid relationship with its surroundings. Glass-walled bedrooms rub shoulders with fruit trees and an ocean of grass dotted with the garden lights. The sense of uniqueness is enhanced by the fact it sits within the walled gardens of an 18th-century mansion. Old and new collide, stone walls contrasting with huge glass windows, structured perimeters with lightness and transparency.”
