Gwynn's on King officially opened its doors at 154 King St. in Charleston, marking the expansion of the luxury retailer. The new three-story site follows the business's acquisition of the building in December 2024.
Why it matters
The opening represents a significant downtown expansion for a heritage brand, adding a multi-story retail footprint alongside potential secondary income from upper-floor apartment rentals.
The firm purchased the three-story building for $3.1 million, a scale shift from the 600-square-foot store opened in 1967. The project was completed roughly two years after the initial site investment.

The details
The owners, Marshall and Madison Simon, renovated the historic structure and discovered an antique shoe in the ceiling, which they now display in a custom glass wall nook to honor traditional building protections. The property is designed to support retail across the lower levels, with the third floor slated for month-to-month residential rentals to maximize building utility.

Market Landscape
This opening reflects the wider industry trend of luxury retailers leveraging historic downtown assets for mixed-use operations. The transition echoes the strategic growth patterns of long-tenured regional brands seeking to diversify revenue through residential space.
Operators looking to expand should evaluate the financial viability of mixed-use property acquisitions, specifically how residential rental income can offset high-cost urban retail leases. Ensure that building renovations include due diligence on historical elements to manage compliance costs and preserve site character.
The takeaway
The move demonstrates how retailers are utilizing vertical space to improve ROI in expensive real estate markets. Business owners should monitor local zoning codes regarding mixed-use conversion when evaluating commercial real estate acquisitions.
