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.

By Invest Cambodia Editorial · Updated June 28, 2026 · 11 min read

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.

Invest Cambodia Editorial reviews individual projects so foreign buyers can separate the sales story from the underwriting. This page is an independent review of Diamond Bay Garden through the lens of its Koh Pich location: what the OCIC island address adds, what premium stock costs, how rental demand and seasonality behave, and the diligence a higher-capital purchase still requires on invest-cambodia.com.

The 2026 backdrop is roughly 76,000 to 80,000 Phnom Penh condo units, 3% to 4% annual absorption, an 8.9% banking NPL ratio, and foreign buyer share led by Poland, Russia and France per realestate.com.kh.

How does Diamond Bay Garden fit the Koh Pich district?

Diamond Bay Garden is a residential project positioned on Koh Pich, the reclaimed central district that OCIC master-planned at the confluence of the Tonle Bassac and Mekong rivers. It belongs to the premium tier of the foreign-buyer market, where the location carries the investment case as much as the building itself.

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, not in isolation. The full district profile and the OCIC model behind it are in koh-pich and ocic-developer-guide.

What makes Koh Pich a premium OCIC address?

Koh Pich is a premium address because it pairs a central island position with a full amenity set and brand recognition, the three ingredients that support durable end-user demand. OCIC’s master-planned model concentrates schools, retail, event space and residential towers in one walkable district, which sustains both tenant and resale interest.

Banking NPL8.9% ratioFavour completed over off-plan
Stamp dutyThrough 31 Dec 2026Incentive window active
Foreign quota70% per buildingVerify 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, not just 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?

A Diamond Bay Garden unit costs the headline price plus transfer fees, legal review, furnishing and ongoing management, and because OCIC premium entry commonly starts from about $106,000, the total acquisition cost sits materially above an entry-tier purchase. Budget every line separately rather than anchoring on the brochure figure.

Cost lineIndicative rangeBuyer action
Unit price (premium entry)From about $106,000Confirm exact stack and floor
Legal review$800 to $2,500Use a Cambodia property lawyer
Transfer and stamp dutyLower through 31 Dec 2026Model under the incentive window
Furnishing$5,000 to $15,000Budget for rental readiness
Management fee$40 to $80 per monthConfirm the sinking fund
Vacancy allowance1 to 2 months per yearStress-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?

Premium Koh Pich stock usually delivers lower gross yields than cheaper units because entry prices are high, so any 12% to 15% gross yield claim should be treated as marketing only with no guarantees. Underwrite net yield after vacancy, management and maintenance, and model to the steady long-term tenant base rather than event-day peaks.

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?

Diamond Bay Garden and Megakim entry towers sit at opposite ends of the Phnom Penh ladder. Diamond Bay Garden on Koh Pich competes on a premium island address and end-user demand from about $106,000, while Megakim entry stock competes on the lowest ticket and payment-plan access from about $40,000. They serve different buyers, not the same buyer at two prices.

FactorDiamond Bay Garden (OCIC, Koh Pich)Megakim entry tier
Indicative entryFrom about $106,000From about $40,000
PositioningPremium island districtSingle affordable towers
Demand driverEnd-user, brand-ledPrice-led, yield-led
Gross yield profileTypically lowerPotentially higher
Resale demandDeeper, brand-ledThinner, price-led
Best forCapital quality, end usersLowest 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.

What 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.

AdvantagesDisadvantages
Central Koh Pich island addressHigh premium entry from about $106,000
Full master-planned district amenitiesGross yields lower than entry tier
Brand-led end-user resale demandPremium price not matched by premium yield
Walkable, self-contained locationEvent-day seasonality skews short-stay demand
Capital-quality story for longer holds70% quota can fill fast in popular towers
Deeper re-letting demand during vacancyThin resale market still applies citywide

The pattern is consistent: every strength carries a matching cost. 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?

The main risks are paying the island premium without verifying the specific unit, over-relying on the Koh Pich brand, quota pressure in popular towers, event-driven demand assumptions, and assuming a premium price guarantees a premium yield. A strong district reduces some risk but does not remove project-level diligence.

  1. Brand-premium overpay: Verify the exact stack, floor, view and finish; a famous island does not justify every individual unit’s price.
  2. Quota pressure: Request the written foreign quota ledger before deposit, because near-full Koh Pich towers narrow your future resale pool.
  3. Seasonality over-reliance: Underwrite to the steady long-term tenant base, not the convention-centre event-day peak.
  4. Off-plan timing: On any unfinished phase, tie instalments to verified construction milestones and use escrow where available, given the 8.9% NPL backdrop.
  5. 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.

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?

Run disciplined diligence scaled to the higher capital at risk: verify the licence and land title with a Cambodia lawyer, confirm the foreign quota in writing, inspect a completed building on Koh Pich, model net yield to the long-term base, and for any off-plan phase tie payments to construction milestones with escrow where available.

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 to judge how OCIC stock actually ages and maintains, not only the showroom, 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.
