Diamond Bay Garden is a 39-storey, 591-unit waterfront condominium on Koh Pich — Diamond Island — the master-planned district built as an extension of Phnom Penh’s central business core. Listed as completed in 2025, it belongs to the island’s finished premium stock rather than its render pipeline: buyers can walk actual units, test the common areas and verify the river views before committing, removing the construction risk attached to most investment product in the capital.

The scheme pairs scale with unusually complete hardware: a rooftop sky bridge connects the towers, two basement levels hold 1,378 cars and 216 motorbikes, and residents keep a swimming pool overlooking the Bassac River, a gym and yoga room, a sky garden and sky bar, a children’s playground and housekeeping services, with 24/7 reception and video surveillance behind them. Units run from studios to three-bedroom apartments, plus select shophouse configurations, across 60–217 m².

Koh Pich concentrates more than 700 businesses alongside riverwalks and landscaped public space — one of the few Phnom Penh districts where tenants can live, work and spend their leisure time without crossing the city. With pricing from US$226,000 and listing estimates of 6% gross and 4% net yield, Diamond Bay Garden suits investors who prefer income-ready, inspectable stock with three-river views over off-plan promises.
