Decking, Pergolas & Timber Structures

PN Landscapes builds garden decking, pergolas, gazebos and other timber structures in Uckfield and East Sussex, using ground-contact treated frames on concrete foundations with softwood, hardwood or composite boards.

Timber brings warmth to a garden that stone alone cannot: a deck stepping out from the kitchen, a pergola over the dining table, or a raised platform that turns a slope into somewhere to sit. We have been building timber structures alongside our paving and walling since 1997.

This page covers what we build, the timber and composite options, and the construction details that decide whether a deck lasts five years or twenty-five.

Construction

How we build decking that lasts

Decks rarely fail at the boards. They fail at the frame and the ground underneath, usually because water has been left to sit against timber.

  • Ground preparation: vegetation removed, membrane laid and the ground shaped so water drains away.
  • Foundations: posts or pads set in concrete, or adjustable pedestals over paving, so the frame never sits on soil.
  • Frame: pressure-treated structural joists, Use Class 4 timber in ground contact, and cut ends re-treated.
  • Ventilation: gaps between boards and space beneath so the timber dries out.
  • Fixings: stainless or coated screws that will not rust or stain.

Timber or composite decking?

Board typeUpkeepGood to know
Treated softwoodClean yearly; re-treat every few yearsMost affordable and natural-looking. Can be slippery in shade.
HardwoodOil to keep colour, or leave to silverDense and long-lasting, at a higher price.
CompositeWash downDoes not splinter or need staining. Higher upfront cost; quality varies by brand.

Most garden decks do not need planning permission, but a deck or platform more than 30cm above the ground does, as can decking at listed buildings. We will tell you if your design needs checking.

Questions we are asked

Frequently asked questions

How long does decking last?

A well-built treated softwood deck typically lasts 15 years or more with care. Hardwood and good composite decks can last longer. The frame and the drainage beneath matter most.

Is decking slippery?

Timber can become slippery in shade and wet weather. Regular cleaning, grooved or anti-slip boards, or composite decking all help.

Can you build decking on a slope?

Yes. A raised deck on posts is often the simplest way to create level space on sloping ground, though planning rules apply above 30cm.

Do pergolas need planning permission?

Usually not in a back garden if they stay within the height limits for outbuildings: 2.5 metres within 2 metres of a boundary, and up to 3 metres or 4 metres with a dual-pitched roof elsewhere.
