1339 Main St, Columbia, SC 29201

The City of Columbia and Trinity Partners are pleased to present Washington Square, a landmark development opportunity in the heart of downtown. Built in 1973 and encompassing 90,402 square feet, this iconic brutalist-style office building is poised for transformation as part of Project Catalyst—the City’s initiative to leverage public assets and private investment to drive growth, strengthen the local economy, and enhance quality of life.

Strategically located within walking distance of the State House and the University of South Carolina, Washington Square offers unmatched access to Columbia’s civic, cultural, and commercial core. The property sits at the center of a thriving district, surrounded by retail, dining, and office activity, and adjacent to the City of Columbia’s $50 million Municipal Complex and Core Spaces’ $250 million mixed-use development.

Ideal redevelopment scenarios include a full-service/boutique hotel, a mixed-use residential and retail project, or creative office and hospitality combinations. Columbia seeks a development partner who shares its vision for long-term growth and will work collaboratively to maximize the return on investment for all stakeholders.

Washington Square represents a rare opportunity to reimagine a historic property in Columbia’s center of commerce and culture—creating a dynamic, high-impact project that both honors the city’s past and advances its future.
