Garden Rooms & Annexes with Hardie® Plank Cladding
These projects all feature Hardie® Plank external cladding, a fibre cement weatherboard that offers the look of painted timber without the upkeep. Available in a wide palette of colours and two profile types, Hardie® Plank is valued for its durability, low maintenance finish, and Building Regulation compliance when positioning close to a boundary.
The examples below highlight how different designers have implemented Hardie® Plank to create varied looks – from bold monochrome schemes to mixed colours for a contemporary twist. Some have paired it with contrasting window frames, while others have opted for a unified palette.
