The Collective at One Sophia首福
The defining mixed-use urban icon in Singapore's historic Civic and Cultural District (District 09). Rising on the former Peace Centre and Peace Mansion site, One Sophia synthesizes a 13-storey Grade A commercial office tower, 127 strata retail and dining spaces, and The Collective at One Sophia—two sculptural 19-storey residential towers comprising 367 luxury apartments. Designed by French architect Jean François Milou (studioMilou) and ADDP Architects, offering unprecedented Core Central Region (CCR) entry from $2,549 PSF.
1. The Transformation of Peace Centre & Peace Mansion
At the crossroads of Sophia Road, Selegie Road, and Middle Road, The Collective at One Sophia represents the comprehensive rejuvenation of the former Peace Centre and Peace Mansion en bloc site. Acquired by an elite consortium comprising CEL Development (Chip Eng Seng), SingHaiyi Group, and Ultra Infinity (KSH Holdings, SLB Development, and Ho Lee Group), the 7,118 sqm (approx. 76,618 sqft) land parcel is being reimagined into a premier 56,167 sqm mixed-use landmark.
The architecture by studioMilou Singapore (led by French master architect Jean François Milou, known for the Singapore National Gallery) and ADDP Architects introduces a dramatic "suspended green carpet"—two sweeping curvilinear garden planes that shelter a futuristic retail podium while elevating residents above the urban streetscape into a quiet, landscaped oasis along Mount Sophia.
