Love them or hate them, decks are still very much
part of the garden design scene. It may have seemed like decks were done to
death in every garden installed by the BBC Ground Force team in the ‘80s
and ‘90s. Each week had Tommy Walsh the builder sawing up lengths of timber to
put together a deck at lightning speed, to the strains of an annoying brass band
soundtrack. But they remain popular in the ‘00s (naughties) too, and are often
seen in the show gardens at the many flower shows over the summer.
Decks can be created in a variety of styles to suit all types of garden from
roof terraces to modern courtyards. As they are a natural material, they help to
blend the garden into the surroundings. They have several advantages over
traditional paving choices too. Decking is warm and comfortable underfoot and
great for children to play on, better than stone or concrete in coping with
tumbles. They are ideal for constructing over uneven ground, or taking account
of a large drop from the floor of a new extension to the existing garden. You
can hide all manner of cables, pipes and transformers in the substructure.
When choosing the timber, you will need to decide between softwood and
hardwood.
Softwood decking usually means pine, which is the cheapest option too. It is
air dried and then treated with a preservative chemical, which binds to the
lignin in the timber, and stays in the timber. Boards are either smooth or
grooved. Grooved boards are often marketed as an anti-slip choice. However, if
the grooves are running along the direction in which you are walking, there is
little slip resistance.
Another softwood option is Western Red Cedar, which comes from North America
and Canada, where it grows in mixed forests. These are managed under sustainable
forest management principles, audited by third party inspection. Virtually 100%
of the timber harvested is used, either as timber , wood pulp or energy to run
the mills. It is a lovely choice for decking. The wood contains natural oils,
which make it naturally resistant to decay and insect attack. It contains no
pitch and doesn’t need the application of a preservative. It is a warm amber
brown colour, which fades to silver-grey and it is resistant to warping and
twisting.
Hardwood decking comes from South America. Ipe is 3 times harder than oak and
a rich dark brown colour, which ages to a lighter brown. Yellow Balau from
Malaysia is a yellowish brown.
Green oak is sometimes suggested as a decking material, but it tends to warp,
so is not the best choice.
Take advice from the supplier as to the best type of screws to use for
decking boards, as the wrong screw will react with the timber and cause
staining.
When deciding on the size of the deck, put out your table and chairs, so you
get an idea of how much space you need to leave for them and around them. You
might also want space for pots or spaces to plant in the ground between the deck
and the house walls. An integral sandpit is nice for children and it’s easy to
sweep the sand back in afterwards.
So think again about decking as a choice for your garden. After all, at this
time of year, what better place to put the ‘deck’ chairs for a spot of summer
relaxation.The author Linda Regel runs a garden design and
