James Hardie is at the forefront of this trend, offering a complete exterior solution by bringing together its innovative new Autoclaved Aerated Concrete (AAC) panels, called Hardie™ Gravis™ Panel, and its trusted Hardie™ fibre cement cladding.

This powerful combination allows you to design for the whole of your home, creating a cohesive, mixed-material exterior that is both impressive and resilient.

How can I blend these materials to match my home style?

The James Hardie Modern Homes Forecast Report 2026 reveals that contemporary Australian homes are increasingly favouring materials, which allow for incredible versatility in design, from sweeping curves to clean lines and soft textures.

Here’s how to mix and match Hardie™ Gravis™ Panel and Hardie™ fibre cement products to get the look in three key home styles, as identified in the report:

Box Modern

• About the look: The Box Modern style is characterised by clean lines, geometric forms and a sophisticated, minimalist aesthetic.

• How to use Hardie™ Gravis™ Panel: Hardie™ Gravis™ Panels create a smooth, uniform surface that is ideal for rendering. You can render in various textures and colours to help define the signature Box Modern shape and flat roofline. It works perfectly on lower levels as an ideal rendered base. Tip: Consider a thick texture to make your Box Modern facade pop.

• Hardie™ Fibre Cement pairing: Use Axon™ Cladding for sharp vertical lines that contrast with the rendered sections, or Stria™ Cladding Fine Texture for strong horizontal definition, enhancing the architectural rhythm. The clean edges of Hardie™ Axent™ Trim can further accentuate the distinct box forms.

Japandi

• About the look: Japandi style fuses minimalist structures with a nature-led design; think crafted simplicity for tranquil homes.

• How to use Hardie™ Gravis™ Panel: Lightweight yet robust, Hardie™ Gravis™ Panels simplify installation and support multiple aesthetic options. It’s the ideal product to add texture to your Japandi home.

• Hardie™ fibre cement pairing: When paired with Hardie™ Gravis™ Panel, Axon™ Cladding’s clean, vertical lines easily emphasise a refined sense of geometry and flow, which the Japandi house style loves. You can also use Hardie™ Fine Texture Cladding to achieve a matte, rendered finish that complements Japandi’s minimalist aesthetic.

Modern Coastal

• About the look: Modern Coastal design evokes a relaxed, airy feel with natural textures and a connection to the outdoors.

• How to use Hardie™ Gravis™ Panel: Ideal for solid, rendered sections that ground the home, offering a base for a cool, calm backdrop. Its thermal properties also contribute to a comfortable indoor environment, ideal for coastal living.

• Hardie™ fibre cement pairing: Combine with Linea™ Weatherboard for classic horizontal lines reminiscent of traditional beach houses, or Hardie™ Brushed Concrete Cladding for an organic, flowing texture that adds depth and character, mimicking natural coastal elements.

Modern Classical

• About the look: Modern Classical blends timeless elegance with contemporary functionality, often featuring softer curves, subtle textures and refined proportions.

• How to use Hardie™ Gravis™ Panel: A substrate for a sophisticated, rendered finish that provides a contemporary twist on traditional masonry. Tip: Use on intertenancy walls and blade walls to highlight the classical proportions of the Modern Classical style.

• Hardie™ fibre cement pairing: Integrate Hardie™ Fine Texture Cladding for a subtle, fine-render finish that adds understated elegance, or Stria™ Cladding Fine Texture for robust, versatile lines that can be installed horizontally or vertically to complement the sleek and timeless design elements of this look.
