Completed Project

Northbridge Project

Architect: John Bradley

Builder: Bellevarde Constructions

Location: Northbridge, Sydney NSW

System: Geothermal Exchange with Vertical Ground Heat Exchanger

Capacity: 80kW


Project Brief/Scope: 

  • High-end residential project
  • Pool, spa, and domestic water heating
  • Wine cellar temperature and humidity control system
  • Closed-loop hydronic vertical ground heat exchanger
  • Narrow work-site
  • Quiet operation

CWL Group has been asked to design and install a premium heating and cooling system for a high-end residential client, successfully navigating such project challenges as:

  • An extremely narrow driveway which made it difficult to maneuver large drilling machinery in, around, and out of the property.
  • Residential noise restrictions imposed by the local council
  • An architectural design that provided limited space for heating and cooling fan-coil units, necessitating the use of Building Information Modeling (Revit) to determine how best to incorporate the required equipment whilst avoiding clashes with other services.

CWL Group is well-versed in navigating difficult building sites, and they used their decades of experience to plan the installation of the geothermal exchange system’s vertical ground heat exchanger at the Northbridge residence. This project was one of the most difficult to date, with an extremely narrow driveway yielding complexities in mobilsing the drilling equipment into place.

After careful planning and multiple site visits to strategise the best approach, the bores have been successfully drilled and the project is well underway. The Northbridge project will show future clients how a ground-source heating and cooling system is achievable on tight residential lots, no matter how difficult the site may seem.

We engaged CWL for the geothermal exchange and HVAC works on our unique project in Bellevue Hill and were selected based on pricing and their previous experience. It turned out to be the best choice in subcontractors we made for the whole project. Their professionalism, work ethic, expertise and willing to help wherever needed made a highly complex services installation that much easier, and more efficient than expected. I’d like to personally thank James and the site team who put the extra effort in at all times to get our project over the line with remarkable results. Highly recommended Subcontractors and mechanical consultants.
