More about this product

18 at Chatswood is a newly developed boutique residential building designed to harmoniously blend into the natural landscape around it and make use of the views over the treetop canopies. The façade was constructed with a cladding of ExoTec Vero and James Hardie’s RAB™ Board for a complete system that complies with Building Code Australia (BCA) for non-combustible façade elements and provides excellent weather resistance

Project Name 18 at Chatswood
Architect Mayoh Architects
Location Chatswood, NSW
Builder Novati Constructions and Goal Interiors

The contemporary 7-story building has a selection of one and two-bedroom apartments and three-bedroom penthouses. The design was driven by the site’s specific conditions, orientation and existing neighbors. Situated in a gully, the building and landscape needed to fulfill several key elements:

  • Fit into the neighborhood’s bushland environment
  • Maintain privacy and amenity to neighboring properties
  • Incorporate solar access
  • Accommodate for the stormwater and overland flow prevalent on the site


Novati Constructions gave the building a warm, modern vibe using a variety of finishes in a predominantly neutral palette:

  • White render
  • Charcoal grey render
  • Metal
  • Concrete look ExoTec Vero cladding
  • Natural timber elements

This mixture of materials complement each other to create a building that feels like a natural extension of the surrounding bushland. RAB Board is lightweight and easy for sub-contractors to work with giving time savings since before the installation of the Exotec Vero, there is no need to go back to patch torn sarking. Once the ExoTec board has been installed, the job is complete.

Façade Design

The eastern façade’s large surfaces required a design that would reduce the bulk scale of the building while providing contrast against other building elements. James Hardie’s ExoTec Vero was used due to its easy and quick installation, low maintenance requirements and its aesthetically-pleasing attributes that resembled in-situ concrete.


The project manager commented on the cost-saving results of using a concrete color to lower maintenance requirements and the visually appealing results after the build was complete. In February 2020, Australia experienced a storm period when the complete façade system of ExoTec Vero and James Hardie’s RAB™ Board proved its worth under difficult conditions with no leakage.
