TIMBER .(70).
TIMBER
When choosing timber for landscape furniture, cladding, and raised walkways in the United Kingdom, it's important to select a type of wood that is durable, resistant to the elements, and suitable for the environment. Here are some of the best types of timber to use, along with the reasons why they are well-suited for outdoor applications:

1. Western Red Cedar
Reasons:
- Durability: Naturally resistant to rot, decay, and insect damage.
- Weather Resistance: Performs excellently in wet conditions due to low moisture absorption.
- Aesthetic: Rich, reddish-brown colour that weathers to a silver-grey over time, offering a classic look.
- Lightweight: Easy to work with and less prone to warping or shrinking.
- Sustainability: Often sourced from responsibly managed forests.
Uses:
- Cladding, garden furniture, decking, raised walkways, fencing, and pergolas.
Regions Found in the UK:
- Western Red Cedar is primarily imported from North America, as it is not native to the UK. It can be found in timber merchants across the UK.
Important Considerations:
- Requires minimal maintenance due to its natural weather resistance, but periodic cleaning will help maintain its appearance.

Uses:
- Cladding, decking, garden furniture, external joinery, and outdoor structures.
Regions Found in the UK:
- Accoya is widely available from timber merchants across the UK, although the raw material (Radiata Pine) is sourced from New Zealand.
Important Considerations:
- It’s a high-end, long-lasting option, but it can be more expensive compared to traditional softwoods.

- Aesthetic: Choose a timber that complements your design vision (e.g., Oak, Sweet Chestnut).
- Sustainability: Opt for locally sourced or FSC-certified timber to reduce environmental impact (e.g., Larch, Sweet Chestnut).
- Work-ability: Consider how easy the timber is to work with, especially for DIY projects (e.g., Douglas Fir, Sweet Chestnut).
Each of these timber types has unique characteristics, and the best choice depends on specific requirements, such as durability, aesthetic, and cost
