Diamond Bay Garden Review: Koh Pich OCIC Project 2026
Diamond Bay Garden on Koh Pich: how OCIC's island address shapes pricing, amenities, foreign quota, rental seasonality, pros, cons and buyer due diligence.
Quick answer: Diamond Bay Garden is a premium-tier residential project positioned on Koh Pich (Diamond Island), the reclaimed central district master-planned by OCIC in Phnom Penh. Its case rests on a recognisable island address, full district amenities and end-user demand, not the lowest ticket. Premium Koh Pich stock prices above the $1,800 per sqm city average, with OCIC premium entry commonly from about $106,000, far above the entry tier where Megakim starts near $40,000. Buy it for capital quality and demand depth, and verify quota, district fit and net yield before deposit.

How does Diamond Bay Garden fit the Koh Pich district?
The district is the defining variable for any Koh Pich purchase. OCIC turned a sandbar into a high-density, mixed-use island holding residential towers, the convention and exhibition centre, international schools, retail streets and event venues, all inside a walkable, self-contained masterplan. For a foreign buyer, that concentration of amenities is what supports both resale and rental demand from end users, because a recognisable, complete district holds interest better than an isolated tower elsewhere in the city. A Diamond Bay Garden unit inherits that district premium, so the building should be judged on how well it sits within Koh Pich, its position, view, frontage and proximity to the island’s anchors. The full district profile and the OCIC model behind it are in Koh Pich and OCIC Developer Guide.
| 2026 metric | Indicative value | Buyer use |
|---|---|---|
| Phnom Penh avg price | $1,800 per sqm | Baseline vs district premium |
| Foreign quota cap | 70% per building | Above ground floor only |
| Banking NPL ratio | 8.9% | Developer completion risk |
| Stamp duty window | Through 31 December 2026 | Registration timing |
What makes Koh Pich a premium OCIC address?
| Factor | Phnom Penh 2026 | Koh Pich premium read |
|---|---|---|
| City condo stock | 76,000 to 80,000 units | District demand more resilient |
| City average price | $1,800 per sqm | Koh Pich trades above average |
| OCIC premium entry | From about $106,000 | Premium-band, not entry-band |
| Banking NPL | 8.9% ratio | Favour completed over off-plan |
| Stamp duty | Through 31 Dec 2026 | Incentive window active |
| Foreign quota | 70% per building | Verify remaining allocation |
The premium is the trade-off, not a free lunch. Towers on Koh Pich typically price above the $1,800 per sqm city average and rarely appear in entry budget bands, so the buyer pays for the address and the demand depth it buys. That depth matters most on exit and during vacancy: a recognisable district tends to re-let and resell faster than an isolated building, which is the real value of capital quality in a market with thin citywide liquidity. The discipline is to confirm the premium is reflected in genuine end-user demand for your specific stack as well as in the island’s reputation. The price-tier comparison against affordable stock sits in Megakim VS OCIC Entry Price.
How much does a Diamond Bay Garden unit cost?
| Cost line | Indicative range | Buyer action |
|---|---|---|
| Unit price (premium entry) | From about $106,000 | Confirm exact stack and floor |
| Legal review | $800 to $2,500 | Use a Cambodia property lawyer |
| Transfer and stamp duty | Lower through 31 Dec 2026 | Model under the incentive window |
| Furnishing | $5,000 to $15,000 | Budget for rental readiness |
| Management fee | $40 to $80 per month | Confirm the sinking fund |
| Vacancy allowance | 1 to 2 months per year | Stress-test net yield |
The premium positioning changes the maths. On a unit from about $106,000 the soft costs are a smaller percentage than on a $40,000 entry purchase, but the absolute capital at risk is higher, so the quality of the district and the developer has to justify it. Account for the stamp duty incentive through 31 December 2026 and the capital gains tax deferred to 1 January 2027 in your model, both explained in Cambodia Property Taxes Fees 2026. A premium price only makes sense when the demand depth behind it is real and verifiable.
What rental yield and seasonality should you expect?
The yield logic is plain arithmetic: a premium unit costs more per square metre while achievable rent does not rise in the same proportion, so gross yield compresses relative to entry stock. Koh Pich adds a seasonality nuance because the island hosts the convention and exhibition centre, which can lift short-stay demand on event days while quieter weeks lean on end-user and long-term tenants. The safe approach is to underwrite the long-term base and treat event-day uplift as upside, not the core assumption. Model occupancy near 85%, verified management fees and one to two months of annual vacancy. Foreign tenant demand still concentrates in central and well-amenitised areas, supported by a buyer mix of 9% Polish, 9.6% Russian and 7.4% French shares per realestate.com.kh, with the underwriting method in Phnom Penh Rental Yield Guide.
How does Diamond Bay Garden compare to Megakim entry stock?
| Factor | Diamond Bay Garden (OCIC, Koh Pich) | Megakim entry tier |
|---|---|---|
| Indicative entry | From about $106,000 | From about $40,000 |
| Positioning | Premium island district | Single affordable towers |
| Demand driver | End-user, brand-led | Price-led, yield-led |
| Gross yield profile | Typically lower | Potentially higher |
| Resale demand | Deeper, brand-led | Thinner, price-led |
| Best for | Capital quality, end users | Lowest ticket, yield hunters |
The honest framing is that capital quality and affordability pull in opposite directions. Diamond Bay Garden wins on address, demand depth and resale resilience; the entry tier wins on absolute price and gross-yield potential. A buyer choosing between them is really choosing between a higher-cost, capital-quality position and a lower-cost, higher-risk one. A buyer with under $50,000 cannot realistically enter Koh Pich stock and should read the entry-tier route in Megakim World Corp, while the full tier trade-off is broken down in Megakim VS OCIC Entry Price.

Request the stack detailWhat are the advantages and disadvantages of Diamond Bay Garden?
Diamond Bay Garden’s advantages are the Koh Pich island address, full district amenities, brand-led end-user demand and resale resilience; its disadvantages are high entry prices, compressed gross yields, event-driven seasonality and the citywide thin-liquidity backdrop. The premium positioning is the source of both.
| Advantages | Disadvantages |
|---|---|
| Central Koh Pich island address | High premium entry from about $106,000 |
| Full master-planned district amenities | Gross yields lower than entry tier |
| Brand-led end-user resale demand | Premium price not matched by premium yield |
| Walkable, self-contained location | Event-day seasonality skews short-stay demand |
| Capital-quality story for longer holds | 70% quota can fill fast in popular towers |
| Deeper re-letting demand during vacancy | Thin resale market still applies citywide |
The island address that supports the rent is the same thing that prices the unit above the city average on entry. The address and amenities that protect demand also push the price above the reach of entry buyers and below the gross yield those buyers can chase. A disciplined buyer treats Diamond Bay Garden as a capital-quality, longer-hold decision and weighs it against the affordability and yield case for the entry tier in Megakim World Corp, rather than expecting a premium unit to out-yield a cheap one.
What are the risks and red flags before you deposit?
- Brand-premium overpay: Verify the exact stack, floor, view and finish; a famous island does not justify every individual unit’s price.
- Quota pressure: Request the written foreign quota ledger before deposit, because near-full Koh Pich towers narrow your future resale pool.
- Seasonality over-reliance: Underwrite to the steady long-term tenant base and keep the convention-centre event-day peak out of the base case.
- Off-plan timing: On any unfinished phase, tie instalments to verified construction milestones and use escrow where available, given the 8.9% NPL backdrop.
- Yield inflation: Any gross yield above the high single digits on premium stock needs line-item proof of rent comps, fees, vacancy and furnishing.
Insider tip: Visit Koh Pich on a quiet Tuesday morning and again on a major exhibition day at the convention centre. The same unit can feel calm and congested within the same week, and that swing directly affects the short-stay demand and lifestyle appeal you are underwriting at Diamond Bay Garden.
Which buyer scenarios fit Diamond Bay Garden?
Diamond Bay Garden fits buyers prioritising capital quality, a central island address and end-user demand with budgets above roughly $100,000, while accepting compressed yields. It is the wrong fit for buyers prioritising the lowest ticket, the highest gross yield or a short, certain exit.
| Profile | Goal | Fit | Starting point |
|---|---|---|---|
| Premium end-user | Central island address | Strong | Koh Pich |
| Capital-quality buyer | Resale resilience | Strong | OCIC Developer Guide |
| Entry investor under $50k | Lowest ticket | Weak, prefer Megakim | Megakim VS OCIC Entry Price |
| Yield hunter | Highest gross yield | Weak, yields compress | Phnom Penh Rental Yield Guide |
| Diversifier | Compare island stock | Either | Koh Pich Overview |
Scenario A: A buyer with $130,000 seeking a recognisable central address for end-user resale focuses on a completed, well-positioned Diamond Bay Garden stack, accepting a lower gross yield for brand resilience and demand depth.
Scenario B: A buyer comparing island options weighs Diamond Bay Garden against the wider Koh Pich landscape in Koh Pich Overview and the newer riverfront alternative in OCIC Koh Norea before committing.
Scenario C: A buyer with $45,000 recognises Koh Pich is out of reach and instead evaluates the Megakim entry tier, accepting higher completion and liquidity risk for a far lower ticket.
How should you run due diligence on Diamond Bay Garden?
Premium and brand do not replace verification; they raise the stakes of skipping it, because a Koh Pich unit ties up materially more capital than an entry purchase. Visit a finished tower on the island as well as the showroom to judge how OCIC stock actually ages and maintains, and apply the same red-flag screen used for any developer in Developer Due Diligence Red Flags Cambodia. Confirm ownership mechanics in Foreign Ownership Strata Title Cambodia, follow the transfer-day workflow in Due Diligence Process Cambodia Step By Step, and keep the wider strategy in Cambodia Property Investment Guide 2026 in view.
Closing verification checklist
Before you transfer funds for a Diamond Bay Garden unit: confirm the construction licence and land title with a Cambodia lawyer, request the building’s remaining foreign quota ledger in writing, inspect a completed Koh Pich tower rather than only the showroom, model net yield with realistic occupancy and verified fees, account for the stamp duty incentive through 31 December 2026, and for any off-plan phase tie instalments to verified construction milestones with escrow where available. Compare the premium island case against the entry tier in Megakim VS OCIC Entry Price before committing.
Frequently Asked Questions
Diamond Bay Garden is a residential condominium positioned on Koh Pich (Diamond Island), the reclaimed central district master-planned by OCIC in Phnom Penh. It sits in the premium tier, where the case rests on a recognisable island address and end-user demand rather than the lowest ticket size.
Koh Pich premium stock typically prices above the $1,800 per sqm Phnom Penh average, with OCIC premium entry commonly from about $106,000. That sits far above the entry tier where Megakim launches start near $40,000, so Diamond Bay Garden is a premium-band decision.
Premium island stock does not produce double-digit gross. Ask which rent the figure is built on and whether it is a short-let rate. Premium Koh Pich units usually deliver lower gross yields than cheaper stock because of high entry prices, so underwrite net yield after vacancy, management and maintenance.
Yes. The route is the standard one: strata co-ownership above the ground floor, within a foreign allocation capped at 70% of the building's total private-unit area. Popular Koh Pich towers can fill their foreign allocation faster, so verify the remaining quota in writing before any deposit.
Neither is universally better. Diamond Bay Garden on Koh Pich offers a premium address and end-user demand at a higher entry price, while Megakim entry towers offer the lowest ticket from about $40,000 with payment plans. The choice depends on budget, hold period and whether you prioritise capital quality or affordability.
Yes. Koh Pich hosts the convention and exhibition centre, so event days can lift short-stay demand while quieter weeks rely on end-user and long-term tenants. Underwrite to the steady long-term base, not the event-day peak, and model occupancy near 85% with one to two months of annual vacancy.
