Sold: 41 Chapel Street.

Built in the 1840s and thoughtfully updated over the years, this classic Charleston Single sits in the heart of downtown, walkable to King Street, the design district, and some of the city’s best restaurants.

Inside, original heart pine floors, four restored fireplaces, and a full-length piazza (to name just a few favorite details) combined rich Charleston history with cozy livability.

Proud to have represented the sellers on this one.

Grateful to have represented my clients in the successful sale of 3 King Street, South of Broad.

Perfectly positioned across from White Point Garden on the iconic Battery, this beautifully restored circa 1904 home embodies so much of what makes South of Broad special. Thoughtfully renovated, it offers timeless charm, welcoming interiors, and an incredible location just steps from Charleston Harbor, world-class dining, and some of the city’s most treasured landmarks.

22 Rutledge Ave is one of those rare Charleston properties that offers both the walkability of the peninsula and the privacy of your own backyard retreat. Hard to find this close to downtown, the location off of Colonial Lake boasts space to spread out, plus plenty of room for hosting.

106 South Battery sits on a corner lot along one of Charleston’s most picturesque streets, a historic residence the current owners have called home for thirty years, meticulously preserved and renovated by Artis Construction.

Original beveled glass, a gas fireplace, and a screened porch overlooking the gardens give the home its warmth, while a renovated kitchen with a Sub-Zero and Wolf range and re-pointed brick exterior bring it fully up to date. Four bedrooms, each with an en suite bath, and a three-car garage round it out.

You’re steps from the Battery and the harbor, with the streetscape and mature landscaping that make this stretch of South Battery one of the city’s most iconic. It’s hard to beat that setting.

Breathtaking views of the water, a private garden courtyard, and a house steeped in history—2 Water Street is the home people dream of when they envision a life in Charleston. A rare opportunity to own a distinguished residence along the city’s iconic High Battery, The Nathaniel Ingraham House, circa 1810, offers the best of both worlds: rich architectural significance, thoughtfully restored for modern living, hosting, and entertaining.
