Premium Decking in Woolwich

Decking in Woolwich: Terraces, Riverside Flats and Estate Gardens

Woolwich is where we are based, and its gardens vary more than most: Victorian terraces around the town centre, red-brick family houses, postwar estates, and newer riverside apartments near the Royal Arsenal, Woolwich Common and the Thames Path. A deck for a long terrace garden is a different job from a courtyard terrace behind a new-build block.

The ground changes too. Woolwich sits mainly on Lambeth Group clays and sands over thick London Clay, softening to wetter river alluvium the closer a garden is to the Thames, so footing depth and subframe ventilation are decided plot by plot rather than assumed.

Woolwich is our home base — our headquarters is located right here at Woolwich, South East London. We offer immediate consultation availability and seamless project logistics across all Woolwich neighborhoods.

Which Decking Suits Woolwich Gardens?

On clay and alluvium near the river, composite boards on a ventilated subframe are the usual low-maintenance choice, because the boards themselves will not rot where the ground stays damp. Hardwood suits the larger terrace gardens around Woolwich Common where owners want natural timber and are happy to oil it, and softwood is still a sensible option for a smaller deck that will be kept treated and well ventilated.

For courtyards behind modern riverside blocks, the first question is usually permission rather than material, because the planning rules for decking apply to houses, not flats. Our composite vs timber decking comparison sets out how the materials compare, and the decking installation overview covers how we build.

What Our Woolwich Site Survey Looks At

Every Woolwich garden is different, so the free survey checks the things that decide how the deck should be built:

• Ground and drainage: whether your plot is on clay or closer to the wetter river alluvium, which sets footing depth.
• Flood zone: whether your address sits in Flood Zone 3 behind the Thames defences, checked against the Environment Agency flood map.
• Access: whether materials can reach the garden through a side passage or have to come through the house, which is common on terraces.
• Levels: the fall across the garden and your back-door threshold, which decide whether the deck stays under the 30cm planning limit.
• Flats and shared gardens: whether a freeholder or management company must consent before anything is built.

Whatever the board, every deck is built on a C24 strength-graded timber subframe over a breathable membrane, with joists at 400mm centres (300mm for diagonal layouts) and airflow underneath.

Planning, Flooding and Flats: What to Check Before Building a Deck in Woolwich

Woolwich is in the Royal Borough of Greenwich. Under the Planning Portal rules, garden decking is normally permitted development if it is no more than 30cm above the ground, covers no more than 50% of the garden together with any extensions and outbuildings, and is not forward of the front wall of the house. A raised deck above 30cm, or any decking within the grounds of a listed building, needs planning permission. On designated land such as conservation areas, decking at the side of the house is not permitted development either. The Royal Borough has 23 conservation areas, including Woolwich, Woolwich Common and Royal Arsenal Woolwich, so check with the council if your home is in or beside one.

Much of the land beside the Thames in Woolwich, along with Charlton Riverside and Thamesmead, sits in Flood Zone 3, the Environment Agency's highest-probability zone, and is kept dry by tidal defences and the Thames Barrier at Woolwich Reach. Check the Environment Agency flood map for your address; a raised, ventilated subframe suits ground that can get wet.

The permitted development rules above apply to houses, not flats or maisonettes, so a deck for a ground-floor flat or a shared garden in one of Woolwich's newer riverside blocks may need planning permission and the freeholder's consent. This is general guidance, not planning advice; always confirm with your local council before building. Our full guide to planning permission for decking in London covers every rule in detail.
