Conventional Office Space in Singapore: The Complete Enterprise Guide

Quick answer

A conventional Grade A office involves a direct lease, with layout and branding options subject to the premises and landlord approvals. Confirm the offered term, deposit, fit-out scope and handback obligations. Conventional space may suit a committed multi-year requirement. Flex may suit uncertain headcount or reduced upfront works, but compare actual terms, capacity and total costs.

Conventional Grade A, in plain terms

Grade A offices are Singapore’s premium commercial tier: CBD locations (Raffles Place, Marina Bay, Tanjong Pagar being the three core districts), large floor plates (typically 15,000–30,000 sq ft), high ceilings, and modern building systems, often with BCA Green Mark certification. See our Grade A office pillar page for the full building directory across all three districts.

What that pillar page doesn’t cover — and what this guide adds — is what actually happens commercially once you sign: the deposit, the lease term, the reinstatement obligation at the end, and how all of that compares to simply taking flexible workspace instead.

This guide focuses on conventional Grade A leasing specifically — the commercial framework, technical due diligence, and process. If you’re still deciding between flexible workspace and a direct lease, see our Enterprise Guide to Serviced Offices in Singapore for that comparison, or use our TCO calculator for a direct cost comparison between the two paths.

Singapore’s Grade A office market — Q2 2026

As of Q2 2026, per CBRE, JLL, and Cushman & Wakefield:

Core CBD Grade A rents are in their sixth consecutive quarter of growth — CBRE puts Core CBD Grade A gross effective rent at approximately S$12.50 per sq ft/month (+0.8% quarter-on-quarter), while JLL’s broader CBD Grade A basket shows S$12.19 per sq ft/month (+1.1% quarter-on-quarter). Vacancy is tight: CBRE reports Core CBD Grade A vacancy at a record-low 3.3%; JLL’s vacancy excluding new supply sits at 5.6%, a nine-quarter low. Supply is genuinely constrained — Shaw Tower was the only major Grade A completion in 2026, and JLL identifies Newport Tower as the sole non-strata Grade A completion expected in 2027; the next meaningful wave isn’t expected until 2028. Cushman & Wakefield forecasts a further 4–5% rent growth across 2026.

What a conventional lease actually costs beyond headline rent

• Security deposit: obtain the amount, accepted security form, permitted deductions and refund timing in writing. Landlord requirements depend on the tenant and proposed agreement; paid-up capital is not a universal deposit formula.
• Fit-out costs: confirm whether the conventional unit is bare, fitted or furnished and budget for the works your team requires. A fitted flex suite may reduce the initial works required; confirm customisation, activation charges and handover conditions in the operator’s proposal.
• Reinstatement costs: confirm the agreed handback condition, retained works and removal obligations. Budget from a current contractor or quantity-surveyor estimate for the actual fit-out and lease scope.
• Lease term: conventional Grade A leases in Singapore are commonly 3–5 years or longer, while serviced/flex commitments vary by operator, product and negotiated agreement; an enterprise suite can also carry a multi-year term.
• Rent-free fit-out period: landlords commonly offer 1–2 months rent-free to cover your fit-out works before rent commences, though service charges typically still apply during that period. This can extend up to 6 months for a large-scale commitment — a multi-floor take-up of 100,000+ sq ft on a 5-year-plus lease — reflecting the larger fit-out scope and longer lease term, not a fixed rule.
• After-hours air-conditioning: confirm the building’s included hours, zones, minimum booking duration and current extra-hours tariff before budgeting.
• Stamp duty and legal costs: where Average Annual Rent (AAR) exceeds S$1,000, IRAS lease duty is 0.4% of total rent for leases of four years or less, or 0.4% of four times AAR for longer or indefinite leases. AAR of S$1,000 or less is exempt. Use IRAS’s own Renting a Property guidance and e-Stamping calculator to confirm the current method and calculate the exact figure for your lease, since AAR is based on the higher of contractual or market rent and the rate is set by IRAS. Separately, obtain legal and documentation fee quotations and confirm which party pays them. Confirm the applicable duty, legal-fee responsibility and any documentation charges for each proposed agreement, including flexible workspace.

These figures are general market benchmarks, not quotes for any specific building — confirm current terms directly for any building you shortlist, since they vary by landlord and by your specific negotiated terms.

What to negotiate before you sign

A conventional Grade A lease has more room to negotiate than the headline rent alone suggests:

• Rent-free period length — often tied to lease commitment length and fit-out complexity; larger footprints can sometimes negotiate more.
• Service charge escalation caps — ask whether annual service charge increases are capped, rather than left open-ended.
• Reinstatement scope — clarify in writing exactly what “base-build condition” means for your specific unit before you fit it out, to avoid disputes at lease end.
• Renewal and expansion options — a right of first refusal on adjacent space, or a pre-agreed renewal rate, can matter more over a multi-year term than a small difference in the initial headline rent.

None of these are guaranteed — they are points worth raising during negotiation, and outcomes depend on the landlord, building, and market conditions at the time.

A CBD-wide view: where Grade A conventional space sits in Singapore

• Raffles Place — Singapore’s traditional financial-district core; see our district guide for building-level detail.
• Marina Bay — MBFC, Marina One, and Asia Square anchor this newer, purpose-built financial precinct.
• Tanjong Pagar — a strong concentration of Grade A towers including Guoco Tower, Capital Tower, CapitaSky, and Frasers Tower, increasingly popular with technology and multinational tenants.

Example buildings worth reviewing directly: Guoco Tower, Capital Tower, and CapitaSpring — each building hub carries current tenant mix, specifications, and asking-rent detail.

Sustainability certification and ESG reporting

For an MNC or regional HQ with its own sustainability commitments or investor ESG reporting requirements, the building’s certification tier is a genuine operational input, not just a marketing point.

BCA environmental sustainability requirements and Green Mark certification should be checked separately. For the new buildings, qualifying additions/extensions and major retrofits covered by BCA’s guidance, the relevant gross floor area (GFA) threshold was 2,000 sq m for first planning-permission submissions from 15 April 2008 to 30 November 2021, and 5,000 sq m from 1 December 2021. For additions/extensions, the threshold concerns the increase in GFA. Alterations without major retrofitting are outside this stated requirement. Check the project scope and applicable submission date rather than applying a single threshold to every commercial building.

For certification, request the actual Green Mark scheme and version, award level, any energy designation, validity and certificate scope. Distinguish the base building from a tenant fit-out. Do not treat older award tiers and newer energy designations as one universal ladder; confirm the certification applicable to the shortlisted property.

LEED (the US Green Building Council’s international scheme) uses a comparable Certified / Silver / Gold / Platinum structure and is sometimes held alongside Green Mark by buildings targeting international investors or MNC tenants who report against global rather than Singapore-specific frameworks.

What to ask before shortlisting: the actual scheme/version, award level, energy designation and validity, whether the certification covers the base building, the tenant’s own fit-out, or both, and whether the building publishes energy/water consumption data your sustainability team can cite directly in its own reporting.

Technical due diligence for enterprise occupiers

Beyond floor plate size and location, a technical evaluation for an enterprise-scale fit-out typically covers:

• Floor loading capacity — matters for server rooms, dense filing/archive areas, or specialised equipment
• Power supply and redundancy — available power density per floor, whether dual/backup power feeds exist, and headroom for future load growth
• Connectivity — fibre providers already terminating in the building, and lead time to bring in a new provider if needed
• HVAC zoning and after-hours capability — whether individual floors or zones can run after-hours air-conditioning independently, relevant for trading floors or teams with extended hours
• Floor plate efficiency — the ratio of usable to gross floor area, and how column placement affects your intended layout
• Security and access control — building-level access systems, and how they integrate with your own floor-level security requirements

These are exactly the questions worth raising during a building viewing, alongside the commercial terms already covered above — confirm current specifications directly with the building’s management, since they vary by building and can change with base-building upgrades.

How we manage the process for you

A conventional Grade A lease involves more moving parts than a flexible-workspace agreement — technical specifications, certification tiers, and landlord negotiation all need coordinating alongside the commercial terms. Here’s how we manage that on your behalf:

1. Requirements definition — headcount (current and projected), budget, timeline, technical needs (power, connectivity, floor loading), and sustainability/certification requirements, captured upfront so the shortlist is right the first time.
2. First shortlist within 24 hours, drawn from live availability across Raffles Place, Marina Bay, and Tanjong Pagar.
3. Comprehensive shortlist within 48–96 hours, including technical specifications and certification tier for each building where available.
4. Viewings, arranged directly with the landlord or agent — we coordinate technical due-diligence questions directly with building management alongside the viewing.
5. Negotiation and lease execution — we negotiate commercial terms (rent, rent-free period, escalation caps, renewal/expansion options) on your behalf; no fees are payable by your company in most transactions. Your own legal counsel reviews and finalises the lease document itself.

Throughout, we act as a single point of coordination across landlords, buildings, and technical questions — so your team isn’t managing multiple parallel conversations to get to a shortlist you can actually act on.

Frequently asked questions

How much deposit should we budget for a Grade A lease in Singapore?
Obtain the proposed deposit amount, accepted security form, permitted deductions and refund timing from the landlord in writing; there is no universal paid-up-capital formula.

What is reinstatement, and how much should we budget?
Reinstatement concerns the handback condition required by your lease. Confirm retained works and removal obligations, then obtain a current contractor or quantity-surveyor estimate for that scope.

Should we start with flexible workspace or go straight to a conventional lease?
Compare quotations over the same intended term, specification and headcount. Conventional space may suit a stable long-term requirement, while flex can offer different commitment options. Actual savings, availability, customisation, handover dates and minimum terms depend on the specific proposals; neither immediate occupation nor a short commitment is guaranteed.

Is your service really free for tenants?
Yes. Find Your Next Office’s fees are paid by landlords in most transactions, not by tenants, whether you choose conventional or flexible space.
