NIA by Sansiri
About
Project overview
NIA by Sansiri occupies a strategic position in Sukhumvit 71, offering urban professionals convenient access to Bangkok's vibrant Ekkamai-Thonglor corridor while maintaining a slightly removed setting from the busiest thoroughfares. This positioning balances accessibility with relative tranquility, a rare combination in central Sukhumvit.
The development's Mid-Century inspired design creates a distinctive aesthetic among Phra Khanong's residential options, with the striking blue and yellow color scheme standing out against the neighborhood's typically neutral palette. Common areas are thoughtfully designed to foster community interaction, particularly the ground floor co-working space and the rooftop Sansiri Backyard garden that provides panoramic Thonglor views.
Unit configurations prioritize functional living spaces despite compact footprints, with even the smaller 22.75 sq.m. layouts featuring practical divided areas and glass partitions to maintain natural light flow. The larger 1 Bedroom Plus and 2 Bedroom units (34-54 sq.m.) offer particularly good value for small families seeking proximity to international schools like Bangkok Prep.
The project's location connects residents to both BTS Phra Khanong and On Nut stations, with shuttle service enhancing accessibility to T77 community amenities. While parking ratio (37%) remains lower than ideal for car-dependent residents, the nearby Chalerm Ratch Expressway entrance compensates by providing quick vehicle access to central business districts.
For buyers seeking a well-managed, completed property with strong Sukhumvit connectivity at moderate price points, NIA represents a practical investment in an area continuing to see consistent rental demand from young professionals and small families.
Highlights
- The Chalong Rat expressway entrance is 150m away, putting fast driving access across the city at the doorstep.
- Habito Mall is 450m away, with BTS Phra Khanong further down Sukhumvit 71.
- A rooftop community garden gives residents shared green space high above the street.
- The digital door lock opens five ways, by fingerprint, passcode, key card, key or phone app.
- Passenger lifts travel only to each resident's own floor, keeping access tight and hallways quiet.
- Floors use 8mm laminate, twice the usual 4mm thickness, for a more solid feel underfoot.
