Overview
Kawa Haus is the premium flagship of Sansiri's "Haus" series, located at the quietest edge of the T77 master-planned community. Completed in 2020, this low-rise development (3 buildings, 7 floors) is designed under the concept of "Living as a part of Nature." It distinguishes itself from its predecessors, Hasu and Mori, by offering a more luxurious, organic aesthetic and a significant 150-meter frontage along the Phra Khanong Canal.
The project is famous for its resort-style amenities, including a bamboo-inspired bridge and a unique hot/cold Jacuzzi designed to mimic natural hot springs. In 2026, it remains a top-tier choice for those who want a "hideaway" feel within the city, combining Japanese-inspired tranquility with the convenience of the T77 ecosystem, which includes on-site dining, a dental clinic, and an international school.
Developer
Sansiri Public Company Limited developed Kawa Haus to be the "premium" iteration of their low-rise collection. The project utilizes high-quality materials such as porcelain tiles and premium laminate. Management is handled by Plus Property, with a common area fee (CAM) of 67 THB/sqm. This fee maintains the expansive 8-rai landscape and the specialized "Farm-to-Table" features like the Freshshelf organic produce bins.
Location & Transit
| Station | Line | Distance | Mode |
|---|---|---|---|
| BTS On Nut | Sukhumvit | 1.0km | Shuttle (5 min) |
| Habito Mall | Retail | 450m | Walk (5 min) |
| Pridi 2 Bridge | Road Link | 500m | Drive (2 min) |
Commute Logistics:
- T77 Ecosystem: Residents enjoy a private, safe environment with 24-hour security patrols throughout the entire T77 estate, not just the building.
- Shuttle & Logistics: While it is a 15–20 minute walk to the BTS station, the T77 Shuttle Bus runs every 20-30 minutes, providing a smooth link to On Nut station and the Century Movie Plaza mall.
- Road Shortcuts: The private bridge within the estate allows residents to enter Sukhumvit 71 (Pridi Banomyong) directly, which is a major time-saver for those heading toward Thonglor or the Ram Intra Expressway.
