Decking and Sleepers


The use of Decking enables you to make a unique garden area, which can create a perfect outside living space and can be utilized as an extension of your home.

A decking area may be used as a spot to get people closer together while sipping cocktails and drinks, giving you all a chance to appreciate the long summer evenings. 

Decking can also be used to create raised areas, offering an attractive alternative to paved areas, or to create access ramps to allow your garden area to be enjoyed by everyone.

Available in softwood and hardwood, Sydenhams use superior quality timber, machined from 38mm boards (32mm Finished Size) thus improving the structure of the decked area and reducing the quantity of joists required.

Don't forget, any deck structure will provide years of trouble free life providing it's carefully planned, designed and maintained.
