377 New South Head Rd, Double Bay - HVAC Redevelopment

Value: $1.4 million

Builder/Client: Shape / Fortis

Business Segment / Industry: Commercial fit outs

Location: Double Bay, Sydney

Project Overview

PSB Air delivered a full HVAC redevelopment for a high-end 4-storey, 2,500sqm commercial building in Double Bay. The project required a complete replacement of mechanical systems to support a premium commercial environment while meeting modern energy and sustainability expectations.

The Challenge

This project presented significant engineering constraints:

  • Extremely limited ceiling space across all levels.

  • Integration of multiple complex systems within tight spatial conditions.

  • Coordination with high-end architectural finishes and dense services layouts.

  • Delivering performance, efficiency and constructability without compromising design intent.

The Solution

PSB Air engineered a fully integrated mechanical solution:

  • Installation of a 350kWr VRF heat-recovery air conditioning system.

  • Delivery of commercial kitchen exhaust with fire-rated ductwork.

  • Integration of dedicated outside air systems to improve ventilation performance.

  • Development of a bespoke control system tailored to client expectations.

Approach

A highly coordinated design and delivery strategy was critical:

  • Intensive services coordination to maximise use of limited ceiling space.

  • Collaboration with builder and consultants to align structure, architecture and services.

  • Detailed design refinement and prefabrication where possible to reduce site constraints.

Problem-Solving Expertise

PSB Air applied creative engineering to overcome spatial limitations, rethinking routing and system layouts to fit all services within restricted ceiling voids. A unique, first-of-its-kind control solution was developed to integrate system performance and user requirements, delivering both flexibility and efficiency.

The Results

The completed project delivered a high-performance commercial building that:

  • Maximised usable space despite extreme ceiling constraints.

  • Achieved energy-efficient operation aligned with BCA and Green Star objectives.

  • Provided reliable, flexible climate control across all tenancies.

  • Demonstrates PSB Air’s ability to deliver complex, design-driven HVAC solutions in premium environments.

Frequently Asked Questions

What were the main HVAC challenges at 377 New South Head Rd, Double Bay?

This project involved extremely limited ceiling space, dense services coordination, and the need to integrate multiple systems without compromising high-end architectural finishes. It is a strong example of how commercial air conditioning installation can require careful engineering and coordination in premium fit-out environments.

The 350kWr VRF air conditioning system was selected to provide flexible, energy-efficient climate control across the building while working within tight spatial constraints. VRF air conditioning systems are well suited to premium commercial buildings where performance, control, and efficiency all matter.

Yes. In addition to the core HVAC redevelopment, PSB Air delivered commercial kitchen exhaust with fire-rated ductwork and integrated dedicated outside air systems to improve ventilation performance. This helped create a more complete and reliable mechanical solution for the building.

When selecting an air conditioning company Sydney project teams should look for experience in services coordination, constructability, and high-performance system design. Projects like 377 New South Head Rd show why it is important to work with a team that can solve spatial challenges while still delivering reliable, efficient outcomes.
