Many companies do not want to leave their familiar building, yet need a space they can “present to headquarters” or one strong enough to attract talent. The question: can you upgrade the current office from a Grade B feel toward a Grade A standard, and where do you invest? The short answer: part of it can be done through fit-out, part is limited by the building itself. This article analyses the real upgrade scope — from MEP technical systems, HVAC air-conditioning and PCCC fire safety to finishes — and what lies out of reach.

How Grade A differs from Grade B — and what you can change

The difference between a Grade A and a Grade B office lies in both building-level factors and factors within your own floor. We analysed the grading criteria in detail in Grade A offices in HCMC; here we focus on the part you can change through renovation.

Building-level (hard to change): location, entrance lobby, high-speed lifts, the building’s backup power, management-and-operations standard. These are fixed — if your building is Grade B, the address and shared lobby remain Grade B.

Within your floor (you can upgrade): the quality of interior finishes, the lighting system, the local air-conditioning within the floor, acoustics, the quality of meeting rooms and reception areas, the overall spatial experience. This is exactly the fit-out scope that can lift the perception of an office floor close to a Grade A standard, even if the building is only Grade B.

So “upgrading from B to A” is really about raising the quality inside the floor to the best possible level, within the infrastructure limits the building allows.

MEP technical systems upgrade scope

MEP (Mechanical, Electrical, Plumbing) is the backbone of a high-standard office. The items usually needing an upgrade toward Grade A:

  • Electrical: increase capacity and re-arrange the floor distribution board, add sockets and stub points for a higher device density, and run cabling neatly in trunking and raised access floors.
  • Lighting: switch entirely to LED with office-standard illuminance and colour temperature (typically around 400 lux in work areas, 500 lux in common spaces), and add scene lighting for reception areas.
  • Network infrastructure and stub points: re-run the network cabling and lay out an equipment room (server/rack) meeting cooling and security standards.

The limiting factor: the total electrical capacity the building supplies to the floor is a fixed number. If new demand exceeds capacity, you must work with building management on whether it can be upgraded — and not every building can accommodate it.

Air-conditioning and ventilation (HVAC)

HVAC is the clearest differentiator between a Grade B and a Grade A feel. A high-standard office needs a stable 20–24°C, 40–60% humidity and adequate fresh-air supply (a reference minimum of about 30 m³/h per person). Upgrade directions:

  • Add or replace local air-conditioning within the floor: install a VRV/VRF system zoned for per-area temperature control, replacing an old system with uneven heating and cooling.
  • Increase fresh-air supply: add fresh-air supply fans with heat recovery, improving air quality — a factor staff and international clients increasingly care about.
  • Balancing and commissioning: adjust airflow after installation to ensure no “dead-air” or over-cold zones.

Key limitation: the building’s central air-conditioning system (if any) and the placement of condenser units depend on the building design. Adding a local system must be approved by building management and comply with the fit-out guideline.

Fire safety (PCCC)

When you change the floor layout — adding rooms, erecting partitions, changing the ceiling — the fire alarm and firefighting system almost always has to be modified: repositioning sprinkler heads and smoke detectors to the new layout, ensuring escape routes. This is a legally bound item: every change must be appraised and accepted by a licensed firm, and cannot be self-performed. So an office upgrade must always account for the PCCC step from the design stage, avoiding rework after finishing.

Finishes and spatial experience

This is the most visible part and creates the strongest “Grade A” impression:

  • Lobby and reception: invest in the reception counter, premium finish materials and clear brand identity — the company’s face to international clients.
  • Meeting rooms: good acoustics, standard audio-visual equipment, high-quality glass and partitions.
  • Materials and detailing: upgrade the floor, ceiling and walls from a basic level to a refined finish; clean detailing is the difference between Grade B and Grade A.
  • Acoustics and comfort: use sound-absorbing materials in open spaces, keeping common-area noise at a comfortable level.

Upgrade cost — reference ranges

Cost depends on the starting point and the target level. Broadly, an upgrade project usually sits in the upper half of the VND 4–12 million/m² fit-out range, because the technical items (MEP/HVAC/PCCC) and finish materials carry a higher weighting than a basic fit-out. Add the demolition cost if it is a renovation over existing conditions.

This is a reference range for budgeting, not final pricing. The exact figure only comes after surveying the existing conditions and producing a detailed BOQ — at AIC, from a floor plan, we produce a BOQ estimate within about 4 working hours so you can lock the budget early. To understand the estimate structure, see our fit-out cost guide.

Upgrade in place, or move to a Grade A tower?

The decision depends on whether the “building-level” part matters to you. If the address and shared lobby are not decisive factors for your clients and staff, upgrading in place is usually far cheaper than moving to lease a Grade A floor (30–60% higher rent). If the brand needs the Grade A address and building itself, then moving is the right call — and then you will face the obligation to reinstate the old premises.

Whichever route you choose, upgrading MEP/HVAC/PCCC and finishes in a coordinated way demands a main contractor able to coordinate many interfaces. AIC works to a single-point design-build model, holding the General Contractor plus quality control (GC+QC) role, coordinating licensed partners for the MEP/HVAC/PCCC scope but pulling all schedule and quality responsibility into one place. With over 10 years in the trade (predecessor Nhan Viet from 2016, AIC established in 2019), 60–100 projects a year, two in-house workshops (1,200 m² and 600 m²) and a client base including 9 FDI companies, we have fitted out many office floors in premium towers across HCMC.

Frequently asked questions

Can you fully upgrade a Grade B office to Grade A?

Not fully. Building-level factors (location, shared lobby, lifts, management standard) are fixed. Through fit-out, you can raise the quality inside the floor — finishes, lighting, local air-conditioning, acoustics, meeting rooms — close to a Grade A standard, within the infrastructure limits the building allows.

Which systems does an office upgrade need to invest in?

Mainly MEP (increased electrical capacity, LED lighting to standard lux, network infrastructure), HVAC (zoned air-conditioning and increased fresh air), PCCC (fire alarm and firefighting modified to the new layout, requiring appraisal) and finishes (lobby, meeting rooms, materials, acoustics).

Roughly how much does an upgrade cost?

It usually sits in the upper half of the VND 4–12 million/m² fit-out range because of the higher weighting of technical and finish items, plus demolition cost if renovating over existing conditions. This is a reference range; the exact figure only comes after a survey and detailed BOQ.

Is it better to upgrade in place or move to a Grade A tower?

If the building’s address and lobby are not decisive factors, upgrading in place is usually far cheaper than leasing a Grade A floor (30–60% higher rent). If the brand needs the Grade A building itself, then moving is the right call — but remember to factor in the cost of reinstating the old premises.
