The home

Four bedrooms, renovated in 2013.

Built in 1809 by Lot Hinckley, 29 Union Street pairs the charm of a historic Nantucket home with thoughtful modern updates throughout.

The home has three full floors of living space and sits in the heart of the historic district, just a few short blocks from Main Street. At the rear of the house, a sun-drenched bluestone patio and private side yard make outdoor living easy. Atop this spacious home is a widow’s walk that overlooks Nantucket Harbor.

The home also has three private off-street parking spaces, a rare find in town.

Floor by floor

A walk through the rooms.

First floor

Friendship stairs lead to a formal entry with a powder room. To the right is a sunny living room, and beyond the entry is the formal dining room with a fireplace. Off the living room is a cozy den with its own fireplace. At the back of the house is the spacious, renovated kitchen. It has windows on several sides, Carrara marble counters, stainless steel appliances, a butler’s pantry, and an informal dining area. The kitchen opens directly onto a large outdoor patio with southern exposure. A laundry room is off the kitchen.

Second floor

The second-floor landing opens to a spacious front bedroom with a full bath off the landing. A cozy den with a fireplace is found at the center of the home. A bedroom with a full bathroom is located off of the den. The spacious primary, also served by private stairs off the kitchen, spans the rear of the home and has a bathroom with a tub and a separate shower.

Third floor

A fourth bedroom with a private bathroom is located on the third floor and provides access to the widows walk, with sweeping views of Nantucket Harbor and Downtown Nantucket.
