Building Scale and Office Space for Lease at Cornerstone Building

Building Scale and Office Space for Lease at Cornerstone Building offer flexible workspace options in a professional office environment, suitable for businesses of different sizes and operational requirements in Cua Nam, Hanoi.

Cornerstone Building has a substantial development scale that is relatively uncommon in central Hoan Kiem, where land supply and large contiguous office floors are limited.

Main building specifications

• Upper floors: 14
• Basement levels: Three
• Total floor area: Approximately 48,494 sq.m
• Typical floor plate: Approximately 2,030 sq.m
• Indicative unit sizes: From approximately 115 sq.m to more than 1,800 sq.m

The floor plates can be subdivided according to current availability and the landlord’s technical requirements. This enables the building to accommodate different tenant profiles.

Suitable leasing configurations

• Approximately 115 sq.m for smaller professional teams
• Medium-sized offices for established domestic or international companies
• Large units for businesses with several departments
• Near-full-floor offices for corporate headquarters
• Multiple adjoining areas where available

Floor-plan advantages

The office floors offer several practical benefits:

• Regular and efficient configurations
• Flexible workplace planning
• Suitability for open-plan offices
• Space for hybrid-working arrangements
• Capacity for meeting rooms and executive suites
• Dedicated reception and client areas
• Potential to accommodate several departments on one floor

When evaluating Hanoi office space, occupiers should consider more than the headline area. Floor shape, structural columns, circulation zones and core placement determine how many workstations and functional areas can actually be accommodated.

Cornerstone Building’s large floor plate is especially valuable to companies that want to keep multiple teams together rather than splitting operations across several floors or buildings.

Parking capacity

Three basement levels support the parking requirements of tenants, employees and visitors. Parking remains an important selection criterion in central Hanoi, particularly for companies whose directors, clients and business partners travel by car.

Businesses should confirm their allocated car and motorbike spaces during lease negotiations because parking rights, availability and fees may be separate from the base rent.

Architecture and Office Standards at Cornerstone Building

Architecture and Office Standards at Cornerstone Building combine modern architectural design with professional workspace standards, creating a practical and well-organized environment for businesses in Cua Nam, Hanoi.

Cornerstone Building features a semi-classical architectural style combined with contemporary design. Its distinguished appearance complements the established architecture of central Hanoi while presenting the professional image expected from a Grade A business property.

Notable design features

• Spacious main lobby
• Escalators connecting the first three levels
• Premium exterior materials
• Large, open interior spaces
• Regular office floor plates
• Professional arrival and reception areas
• Landscaped areas and greenery

The main lobby and escalator system create a polished first impression for visitors. This is particularly valuable to companies that regularly welcome corporate clients, investors or international partners.

High-quality exterior materials also contribute to sound insulation and workplace comfort. In a central urban location, controlling traffic noise and external heat can materially improve the employee experience.

Sustainable operations

A particularly important feature is the building’s LEED Platinum certification for operations and maintenance.

For modern organizations, particularly multinational companies with environmental, social and governance objectives, this standard can provide several benefits:

• Demonstrates a commitment to sustainable operations
• Supports more efficient energy use
• Contributes to a healthier working environment
• Strengthens the tenant’s environmental positioning
• Aligns the office with international corporate requirements
• May support internal sustainability reporting

The building’s greenery and landscaping also soften the conventional corporate environment and contribute to a more comfortable workplace.

Office Rental Price and Availability at Cornerstone Building

The indicative rental rate at Cornerstone Building is approximately USD 35–38 per sq.m per month.

This rate should be treated as a market reference rather than a fixed quotation. The final commercial proposal may vary according to:

• Leased area
• Floor and orientation
• Office condition
• Contract duration
• Lease commencement date
• Current vacancy
• Landlord incentives
• Market conditions
• Tenant requirements

When reviewing the office rental price in Hanoi, businesses should calculate total occupancy cost rather than comparing base rent alone.

Costs and commercial terms to confirm

• Base rental rate
• Service charge
• Value-added tax
• Electricity consumption
• Air-conditioning charges
• Overtime air-conditioning fees
• Car and motorbike parking fees
• Security deposit
• Payment schedule
• Fit-out costs
• Rent-free fit-out period
• Handover condition
• Lease-renewal terms
• Reinstatement obligations
• Early-termination provisions
• Signage rights
• Expansion options

The measurement basis should also be verified. Tenants need to establish whether rent is calculated according to net usable, gross or chargeable area. A lower quoted rent does not necessarily produce a lower total cost if the space has an inefficient measurement ratio.

Current office availability

Vacant office units at Cornerstone Building change according to lease expiries, tenant expansion and new transactions. Larger, well-positioned spaces may receive interest quickly because comparable Grade A supply in central Hoan Kiem is limited.

Before making a decision, companies should request:

• The latest vacancy schedule
• Exact floor and unit information
• Net usable and chargeable areas
• Updated rent and service charges
• Current handover specifications
• Parking allocation
• Lease incentives
• Sample commercial terms
• Expected fit-out timeline

A physical inspection is also important. It allows the tenant to assess natural light, floor efficiency, views, lift access, visitor circulation and the practicality of the proposed workplace layout.
