Space was not an issue on this quiet slice of a cul-de-sac in Amagansett, New York. The lot is completely private, and its perch on a 100-foot-high bluff means that its ocean views are also entirely unobstructed. So, what exactly was the problem? The original property, which stood rotting and moldy at the center of the lot, was wasting its opportunity of almost dreamlike seclusion. Robert Young and his namesake firm realized that these red flags wouldn't do for a couple and their three young children who planned to escape here from New York City. They decided to demolish the structure, and instead, they built an L-shaped house that was angled toward the shore. Inside, they separated the common areas from the bedrooms to heighten relaxation, and they chose durable and energy-efficient materials that would stand up to a trio of boys. The goal was to take full advantage of the site, where a family could make the most of their space for years to come. "If one of the grandkids or great grandkids were to preserve and renovate it in 100 years, that would be the highest achievement," Young said.
