Multi-Tenant HVAC & Services Refurbishment – CBX, Milton Keynes

0 comments

The Challenge

The project at CBXII West Wing, located on Midsummer Boulevard in Milton Keynes, required a full refurbishment of mechanical systems across all floors — from the ground floor reception to the fourth-floor offices. The client needed:

  • A flexible HVAC system suitable for multi-tenant occupancy
  • Replacement of outdated R22 air conditioning systems
  • Modernisation of the ground floor reception, including both finishes and services
  • Disruption-free installation across multiple floors
  • Upgraded public health services in all core areas

The Solution

BMS Ltd carried out a complete CAT A mechanical fit-out across all levels of the building, delivering:

  • Installation of Mitsubishi heat recovery VRF systems, allowing simultaneous heating and cooling with individual zone control
  • Each floor was designed to accommodate two tenants, giving each independent control of their climate via centralised controllers and void-mounted chassis units
  • Replacement of outdated R22 systems with new roof-level condensers
  • Full secondary ductwork installation and integration of tile replacement diffusers
  • Modernised reception area with a complete upgrade of services and finishes
  • New public health services in core areas, including hot, cold, and waste water systems, and full sanitary appliance replacement

The Results

The project delivered a modern, energy-efficient and flexible working environment, with:

  • Improved tenant comfort through individual HVAC control per zone
  • Modern air conditioning systems that meet current efficiency and environmental standards
  • Simultaneous heating and cooling capabilities across all floors
  • A transformed and welcoming reception space
  • Fully upgraded public health systems for reliability and compliance
