Long-Stalled 15-Story High-Rise at Fourth and Harrison Advances In SF’s SoMa

BXP, formerly Boston Properties, received an 18-month extension for its $1B office development at 725 Harrison Street in San Francisco. The project, initially announced in 2015, includes 770,000 sq ft of office space and 36,000 sq ft of retail. BXP needs a major tenant to secure financing, citing high construction costs and interest rates. The company points to a surge in office leasing, particularly from AI companies, as a positive sign.
