The Collective at One Sophia in Brief
The Collective at One Sophia is the residential address of One Sophia, the integrated development that replaces Peace Centre and Peace Mansion at the meeting of Sophia Road, Selegie Road and Middle Road. Two residential blocks of 19 storeys stand along Sophia Road above a shared podium, and the rest of the development, with its shops and a separate office address at 1 Sophia Road, faces the busier Selegie Road side.
ADDP Architects designed the development with the French practice studioMilou. The developer’s brochure presents One Sophia as an iconic landmark at the heart of the Civic District, and Tinderbox Landscape Studio designed the gardens of the residents’ deck and the sky gardens.
The Collective at One Sophia Homes and Unit Mix
Block 1A has ten stacks, numbered 21 to 30, and Block 1B has twelve, numbered 31 to 42. Homes begin on the 3rd storey, where the units beside the facility deck carry a private enclosed space and the suffix “-P”, and run up to the 19th storey. Studios and one-bedroom suites account for 134 of the 367 homes, the two-bedroom premium types for 91, and the three-bedroom types for 34. The floor plan page shows every layout, and the unit distribution chart places each home by stack and level.
Why the setting matters at The Collective at One Sophia
The developer places the residences at the forefront of the rejuvenation of the Civic District, a precinct URA has long developed as a heritage, arts and learning quarter. In practical terms, the site sits within walking distance of four MRT lines, the arts schools of Bras Basah, the National Museum and the start of Orchard Road, while Sophia Road itself is a quiet, tree-lined street on the slope towards Mount Emily.
