In 1656 Leonard Weeks, the immigrant, received a grant of land in the part of Portsmouth NH known as Greenland. Near a tidal stream on this property his son, Samuel, built in about 1710 a handsome house from bricks made upon the place and laid in the then fashionable Flemish bond. Over thirty-six feet long and twenty-two feet wide, it has ground story walls over eighteen inches thick. The lower story is eight and a half feet high, the upper story is eight feet. The front windows are over-arched in brick. Timbers are oaken beams twelve by fourteen inches and the sleepers with bark left on are ten inches in diameter.

The genealogy Leonard Weeks of Greenland, N.H. by Reverend Jacob Chapman, 1888, describes the house as follows: "It stands on the Weeks place, a little West of the parade, in Greenland. It is over 36 feet long, 22 feet wide, and the walls of the lower story are 18 inches thick. The bricks in the front wall are of different colors laid in order so as to appear something like the spots on a checkerboard. There was a rent in the walls, at each end of the house, supposed to have been made by the great earthquake in 1755."

"The lower story is 8 feet and 6 inches high. The second story is 8 feet, and the steep pitch of the roof affords ample room for the attic. The windows were originally of small, diamond-shaped glass, set in lead, but have been changed to a later style. The timbers are hard wood – oaken beams, hewn 12 X 14 inches, and the sleepers of red oak, with bark still on, about 10 inches in diameter." This lovely 2-1/2 story Colonial home was sturdily built circa 1710 to resist Indian attacks.

It is generally known as the oldest brick house in New England made of bricks fired on the place. Most other buildings used brick which were carried as ship ballast.

Historical and minor archaeological research has been undertaken on an ancient burying ground on the property. On the property and along the Winnicut River, which borders the property, were saw mills, grist mills, and cider mills, some ruins still being in evidence.
