140 Wireless Road — A Premium, Quiet-Luxury Office in the Heart of Bangkok

140 Wireless Road is one of the most distinctive modern office buildings along Wireless Road, developed by Kian Gwan, the pioneer who introduced Thailand’s first modern office building in the 1970s. Today, they return with a new landmark — a contemporary, functionalist-style office tower designed with simplicity, openness, and understated elegance.

From our visit, the first impression is clear: 140 Wireless feels like a private urban sanctuary. Surrounded by greenery and offering wide-open views of Lumphini Park, the atmosphere is calm, refined, and highly suitable for companies seeking a premium office with privacy in a central location.
