Cosy Garden Rooms designed a versatile 5m x 4m garden playroom in Greater Manchester, ideal for family needs. Finished with durable Hardie Plank cladding and easy-clean interiors, the space connects with the garden and offers room for play, toy storage, and even a small sauna, adapting as the family grows.
Garden Rooms with Composite Cladding
An increasing number of garden room projects now feature composite exterior cladding. It’s an excellent choice, especially if you’re looking for a low-maintenance outdoor building.
Composite cladding materials have significantly evolved in recent years. They are now available in subtle colour palettes and realistic wood-effect finishes. Some products have smooth surfaces, while others feature tactile wood grains. Certain options are even moulded from real wood, imprinting the natural grain into the cladding.
The composition of composite cladding varies. Some materials combine real wood fibres with polymers, while others mix synthetic fibres with cement. In both cases, the boards are coloured during the manufacturing process, meaning they don’t require painting to maintain their appearance.
Composite claddings such as Cedral & Hardie Plank have an A2-s1,d0 fire-resistance rating, making them ideal for Building Regulation-compliant garden rooms and annexes. They are particularly popular for garden rooms positioned within 1m of a boundary.
Some garden room designers combine composite cladding with timber finishes. This approach can be very effective, as demonstrated in several of the projects below.
Through years of working with composite cladding, we’ve observed that quality can vary significantly between ranges, with some options being noticeably more expensive than others. It’s important to keep this in mind when comparing your choices. During the design process, we recommend asking to see examples of completed projects using your chosen finish and colour, as this will give you a better sense of how it looks in real-world settings rather than relying solely on images.
The garden room projects below all showcase the use of composite exterior cladding. They are listed with the most recently published examples first, so use the pagination to explore all the projects.
