What Is an Integrated Development
An integrated development is a large-scale mixed-use project that combines multiple uses — typically residential apartments, retail podium, office space, and sometimes a hotel — within a single development on one or adjoining land parcels. The different uses are held as separate strata lots, each with its own certificate of title, within a shared structure and sometimes a shared MCST.
Prominent examples in Singapore include Duo Residences and Duo Tower, Marina One Residences, OUE Downtown, Midtown Modern at Bugis, and Guoco Midtown. These developments are typically located near MRT interchanges and positioned as live-work-play destinations.
For property agents, the key complexity is that different strata lot types within the same development are subject to different rules — for stamp duty, CPF usage, financing, and strata management. Treating all units in an integrated development the same way will lead to errors in client advisory.
Strata Lot Types and Their Land Use
Each strata lot in an integrated development has a designated land use approved by URA. The main types are:
- Residential strata lots — apartments (condominium units). These are treated as residential property for all regulatory purposes.
- Commercial strata lots — retail units, office space. These are treated as commercial property.
- Hotel strata lots — serviced apartments or hotel rooms held under a hotel licence. These are generally not available for individual purchase by retail buyers and are typically owned by institutional investors or a single owner-operator.
The land use designation governs which rules apply. It is not the physical use or the buyer's intention that determines the classification — it is the approved use on the strata lot's title.
ABSD Treatment by Strata Lot Type
Additional Buyer's Stamp Duty (ABSD) applies only to residential strata lots. Commercial strata lots (retail units, office space) are not subject to ABSD, regardless of the buyer's citizenship, residency status, or existing property count.
This creates a significant ABSD difference between buying a residential unit and a commercial unit in the same integrated development:
- A Singapore Citizen buying a residential unit as their second property pays 20% ABSD on the residential unit's purchase price. If they instead buy a commercial retail unit in the same development, no ABSD applies.
- A foreigner buying a residential unit pays 60% ABSD. The same foreigner buying a commercial unit pays no ABSD.
- An entity (company) buying a residential unit pays 65% ABSD. Buying a commercial unit: no ABSD.
When counting a buyer's total property count for ABSD purposes, only residential properties are counted. Owning a commercial strata lot does not affect the ABSD tier for a subsequent residential purchase.
Buyer's Stamp Duty
Buyer's Stamp Duty (BSD) applies to all property acquisitions — residential and commercial alike. The BSD rates differ by property type:
- Residential BSD: Progressive rates from 1% to 6% depending on the purchase price or market value (whichever is higher).
- Non-residential BSD: Progressive rates from 1% to 5% on the purchase price or market value for commercial and industrial property (rates are slightly different from residential BSD).
Agents should calculate BSD separately for residential and commercial units using the correct rate schedule for each type.
CPF Usage
CPF Ordinary Account (OA) savings can only be used to purchase residential property. This means:
- Buyers of residential strata lots in an integrated development can use CPF OA savings for the down payment and to service monthly mortgage instalments, subject to CPF housing withdrawal limits.
- Buyers of commercial strata lots (retail or office) cannot use CPF OA savings. The full purchase price must be funded with cash and commercial financing.
This CPF restriction is a significant practical consideration for buyers comparing a commercial unit purchase against a residential unit purchase in the same development.
Financing and LTV Rules
Financing rules also differ between residential and commercial strata lots:
- Residential units — subject to MAS residential loan rules: LTV limits (75% for first property, lower for subsequent properties), TDSR (55%), MSR (30% for HDB purchases — not applicable here as these are private residential units). Loan tenure up to 35 years (or 30 years for HDB, not applicable). These rules apply to loans from licensed financial institutions.
- Commercial units — subject to commercial property financing rules. LTV for commercial property is typically 70% to 80% depending on the lender and the development. There is no regulatory LTV cap mandated by MAS for commercial property in the same way as residential — each bank sets its own LTV based on credit assessment. Loan tenures are typically shorter (15 to 25 years) and interest rates are usually higher than residential home loans. TDSR applies to commercial property loans for individuals (MAS extended TDSR to commercial property loans in 2013), but MSR does not.
MCST and Management Structure
Integrated developments with multiple strata lot types typically have a more complex MCST structure than a purely residential condominium:
- There may be a main MCST covering shared common property across the whole development (podium, basement, structural elements, shared facilities), and subsidiary MCSTs (also called sub-MCSTs) for each distinct use component — one for the residential tower, one for the retail podium, and so on.
- Maintenance fees (S&CC) are typically charged separately at each level — main MCST fees shared by all strata lot owners according to share value, plus component-specific fees for the relevant sub-MCST.
- Residents of the residential component generally cannot attend or vote at general meetings of the commercial sub-MCST, and vice versa. Disputes about the allocation of costs between components can be complex and may require STB intervention.
Guidance for Property Agents
- Verify the strata lot type before advising on ABSD: Always confirm whether the unit being purchased is classified as residential or commercial on the title before advising a buyer on ABSD liability. Do not assume all units in an integrated development have the same classification.
- CPF and financing vary by unit type: Advise buyers clearly that CPF cannot be used for commercial units and that commercial financing terms differ materially from residential home loan terms.
- Property count and ABSD planning: A buyer holding a commercial unit in an integrated development is not holding a "second property" for ABSD purposes when they subsequently buy a residential property — confirm this when a buyer discloses existing holdings.
- Understand the MCST structure before advising on maintenance fees: Buyers in integrated developments should understand that they may owe both main MCST and sub-MCST fees, and that the total ongoing cost may be higher than a comparable single-use residential condominium.
- Refer to a lawyer for complex structures: Some integrated developments have bespoke legal structures (e.g., unitised retail trusts, hotel management agreements). Buyers in commercial components should engage a lawyer familiar with commercial property before committing.
Summary
Integrated developments combine residential, retail, office, and sometimes hotel uses under a single development, with each component held as separately titled strata lots. ABSD applies only to residential strata lots — commercial lots are ABSD-free regardless of buyer profile. CPF can only be used for residential units. Commercial units are financed at commercial LTV ratios (typically 70–80%) with shorter loan tenures and higher rates. MCST management is more complex, often involving a main MCST and component sub-MCSTs with separate maintenance fees. Agents must confirm the strata lot classification before advising on ABSD, CPF usage, and financing — and should refer buyers in commercial components to a lawyer for due diligence on management structures.
