Overview
Circle Sukhumvit 31 is the third major development in Fragrant Property's "Circle" series, completed in 2017. This 30-storey tower occupies a prime mid-soi position on Sukhumvit 31, widely regarded as one of the most desirable residential streets in Bangkok due to its tree-lined ambiance and proximity to both Asoke and Phrom Phong.
Like its sister projects, Circle Sukhumvit 31 incorporates Moveable Wall Technology, allowing residents to reconfigure their living space on demand. It caters primarily to the large Japanese community in the Phrom Phong area, as well as eco-conscious professionals.
Developer
Fragrant Property Co., Ltd. is known for pioneering "reinvented living" concepts in Bangkok. Circle Sukhumvit 31 carries forward their signature innovations like heat-recovery water systems and vertical gardens, adapted to a tree-lined, family-oriented neighborhood.
Location & Transit
