01 / The site

A slope you feel in your knees.

The lot falls 22 feet from the road to the bluff crest, then another 60 to the water. The village keeps houses well back from the crest, which left a building envelope shaped like a wedge. We spent two mornings on it with the surveyor's grades in hand before we drew a line.

Contours every 2 ft. High point 120 ft, low point 44 ft. Ground generalized from the survey, which stays with the owners.

02 / The brief

A piano that needed a door.

Two people, grown children who visit in August, and a piano that needed a room with a door. They wanted to see the Sound from bed, not from the driveway, and they did not want a house that announced itself to the road.

The living level of Bluff House, a long table and two armchairs in front of tall black windows on the Sound.
PL. 01 / The living level. The Sound fills the north windows from the long table.
03 / The answer

Three levels that follow the ground.

A garage, a study and the mudroom at the road. The living floor eight feet down, with the piano room off the dining room behind a pair of oak doors. The bedrooms another eight feet down, at the crest. From the drive you see a one-story house. From the water you see three.

Light

21 June, from first light to last.

Drag through the longest day of the year. The photograph is the same frame at dawn, noon and dusk; the plate shows where the sun stands and the shadow the house throws at that minute.

06 / The build

A boulder the size of a car.

The stair hall at Bluff House: white oak treads climbing between lime plaster walls toward a skylight.
PL. 04 / The stair hall. Lime plaster troweled twice, white oak treads, the skylight at the top.

The lower footing found a glacial boulder the size of a car. We split it, used half for the terrace steps, and lost three days. The stair hall is lime plaster over block, troweled twice, so the light from the skylight slides down it all afternoon.

A house like Bluff House, on your ground.

The planner starts from this project's size and scope and gives you a fresh band for your town. A site visit is an hour on the lot with an architect and our estimator.
