Examples of Cosy Garden Rooms exterior finishes

Cosy Garden Rooms offer a range of exterior cladding options so you can choose a finish that fits with your intended aesthetic style and the amount of maintenance you want to commit to.

They offer a range of durable timbers including Western Red Cedar, Redwood and Siberian Larch. Each of these timbers is chosen for its aesthetic appeal and long-term durability. Western Red Cedar is prized for its rich reddish-brown colour and knot-free texture. Redwood features comes in reddish-brown to lighter pink tones with a straight, uniform grain. Siberian Larch has a golden to amber hue and has a tight grain with occasional small knots. All these finishes can be left to weather to a silvery grey tone, without affecting the durability of the wood.

For those looking to maintain the new appearance of their garden room or are looking for a finish that requires a minimal maintenance commitment, Cosy Garden Rooms offer composite options. They offer both a cement fibre board called Hardie Plank and composite wood options. Both options are coloured during the manufacturing process and will maintain their colour without the need to repaint. These composite finishes are available in a variety of colours and have an attractive woodgrain texture.

Cosy Garden Rooms offer both uPVC windows and doors and high-spec Aluminium framed options. Doors & windows are available in a range of frame colours so you can pair them with your choice of cladding to create the look you envision.
