Overview
Nia by Sansiri is a fresh, vibrant high-rise that injects a bold "Mid-Century Modern" aesthetic into the Sukhumvit 71 corridor. Completed in September 2023, the 19-storey building is part of Sansiri’s vision to offer "One Step Closer" living—positioning residents at the junction of the trendy Phra Khanong area and major transit routes. The building stands out with its 1960s-inspired color palette of blue and yellow, creating a nostalgic yet modern silhouette.
The project is famous for its strategic connectivity, specifically its proximity to the Chalong Rat Expressway. In 2026, it is a primary target for young urbanites who want the Sansiri brand's prestige and T77 community vibes at a more accessible price point. Every unit features a 2.6m ceiling height and comes fully fitted with high-spec kitchen worktops and smart living integrations.
Developer
Sansiri Public Company Limited developed Nia to capture the mid-range luxury market. The project reflects Sansiri's "Siri Life" philosophy, focusing on aesthetic design and long-term service. Maintenance is managed by Plus Property, with a common area maintenance (CAM) fee of ฿59 per sqm, which covers the rooftop gardens, jogging track, and the 24-hour residents' lounge.
