Frequently Asked Questions (FAQs) When Renting a Grade A Office
1. What is a Grade A Office, and What Standards Define It?
A Grade A office represents the highest tier within the commercial real estate market. These offices are defined by several key standards:
- Location: Situated in a Central Business District (CBD) or major, well-planned urban area.
- Quality & Design: Modern architectural design, premium materials, and adaptable layouts.
- Technical Systems: High-speed elevators, central air conditioning, 100% backup power, and international standard fire protection systems.
- Management & Operations: Professional management by a renowned firm, 24/7 security.
- Amenities: Spacious lobby, smart parking, and extensive support facilities.
Example from Oriental Square by OSI: Oriental Square by OSI, located in Starlake, meets Grade A standards in terms of location, design, infrastructure, management (by Savills Vietnam), and amenities.

2. What Additional Costs Are Involved Besides Base Rent?
Besides the rental fee, tenants should budget for other expenses, such as:
- Management fee (Service charge): For general operations (security, cleaning, maintenance, etc.).
- Parking fee: Charged monthly or per-use.
- Overtime air conditioning fee: Incurred outside of standard hours.
- Interior fit-out costs: Design and construction of the office space.
- Electricity costs within the office: Based on actual consumption.
- Value Added Tax (VAT).
Example from Oriental Square by OSI: All associated costs are clearly outlined in the lease agreement.
3. How Is Grade A Office Rent Calculated?
Rent is typically calculated based on the actual usable area (Net), quoted in VND or USD/m²/month. Factors influencing price include floor height, view, size, and timing of lease. This Net-based pricing method is common in the premium segment and differs from the Gross area-based rental calculation used in some other office spaces in Hanoi.
Example from Oriental Square by OSI: Rent is calculated using the Net/m²/month method, ensuring tenants pay only for the actual used space.
4. What Is the Typical Minimum Lease Term for Grade A Office Space?
The typical lease term is 3 to 5 years, as businesses need stability and often invest significantly in interior fit-outs. This differs from shorter-term lease agreements commonly found in lower-grade office segments in Hanoi.
Example from Oriental Square by OSI: Standard lease agreements range from 3 to 5 years, ensuring long-term commitment and stability for tenants.
5. What Are the Regulations Regarding Deposit and Payment?
The standard deposit is typically equivalent to 3 months’ rent (including rent and service charges). Rent and service charges are paid quarterly in advance. This is a common practice in Grade A office lease agreements.
Example from Oriental Square by OSI: Follows market-standard practices for deposit and payment, offering favorable conditions for businesses.
6. What Outstanding Amenities and Services Do Grade A Offices Offer?
- Building Management System (BMS)
- Spacious lobby, multi-layered security
- Smart parking
- On-site amenities (F&B area, fitness center,...)
Example from Oriental Square by OSI: Featuring high ceilings, high-speed elevators, F&B zone, meeting/multi-purpose rooms, smart parking, and EV charging stations — all integrated within the Starlake ecosystem.
7. Can Tenants Customize Their Office Space?
Yes. Grade A office spaces are typically handed over in bare-shell condition, enabling tenants to creatively design their workspaces to their brand identity during the rent-free period, while adhering to the building’s regulations. This process differs from leasing a residential unit that is furnished.
Example from Oriental Square by OSI: The column-free design gives tenants the flexibility to arrange their office layout in line with their unique style. The leasing advisory team from OSI Holdings and Savills Vietnam provides tenants with comprehensive consultation and technical support throughout the leasing and fit-out process.
