Decking in Eltham: 1930s Family Gardens on Slow-Draining Clay

Eltham is known for its large 1930s estates, including the Progress Estate and Corbett Estate, alongside arts and crafts cottages and Tudor-style homes, many with wide, long gardens near Eltham Palace, Well Hall Pleasaunce, Avery Hill Park and Coronation Green. Those plots have room for a proper entertaining deck rather than a token platform.

Eltham sits on thick London Clay, with pebble gravel patches towards Shooters Hill. The clay drains slowly, so sub-base preparation and subframe ventilation matter more here than in the sandier parts of South East London.

Located just 10 minutes from our Woolwich headquarters via Academy Road and Well Hall Road, we provide fast response times and personal founder-led management for all SE9 projects.

Which Decking Suits Eltham Gardens?

Wide family gardens suit multi-tiered composite decks with integrated steps, flush lighting and balustrades in Millboard or Trex, and hardwood is a strong alternative where the owner wants natural timber. On slow-draining clay, the ventilated subframe matters more than the board choice, because it keeps the structure dry.

With big gardens it is easy to add a deck, a shed and an extension and exceed the 50% garden limit without noticing, so we plan the deck alongside whatever else you intend to build. Our composite vs timber decking comparison covers the material choice.

What Our Eltham Site Survey Looks At

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

  • Drainage: how the clay behaves after rain and where water leaves the garden.
  • Garden coverage: the deck together with any extension, shed or outbuilding, against the 50% limit.
  • Progress Estate: whether your address sits in the conservation area with an Article 4 direction.
  • Trees: mature garden trees and any protection that applies.
  • Levels: how the garden falls from the house and where steps or tiers are needed.

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, Conservation and the Progress Estate: What to Check Before Building a Deck in Eltham

Eltham 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's 23 conservation areas include Eltham Green, Eltham Palace, Well Hall Pleasaunce and the Progress Estate, and the Progress Estate has an Article 4 direction removing some permitted development rights, so check before assuming a deck is allowed if you live on or beside it.

Eltham's large 1930s gardens suit generous decks, but the 50% limit counts the deck together with any extension and outbuildings, so plan the deck alongside any shed or extension. In a conservation area you must give the council six weeks' written notice before cutting or pruning a tree, and the council can respond with a Tree Preservation Order, so a deck layout has to work around mature trees rather than assume they can come out. 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.

Frequently Asked Questions: Eltham Decking

How do you handle sloped gardens in Eltham?
Yes. We frequently build wide, multi-level composite decks with flush step transitions, connecting kitchen bifold doors to lawn areas in Eltham 1930s properties.
Do I need planning permission for decking in Eltham?
Usually not, if the deck is no more than 30cm above the ground, covers no more than half the garden together with other outbuildings, and is not forward of the front wall of the house. Raised decks above 30cm and decking in the grounds of a listed building need permission. Eltham has several conservation areas, including Eltham Green, Eltham Palace and the Progress Estate. We are not planning consultants, so please confirm with the Royal Borough of Greenwich.
Does the Progress Estate Article 4 direction affect decking?
It can. The Progress Estate conservation area has an Article 4 direction which removes some permitted development rights, so check with the Royal Borough of Greenwich before building anything there. Outside it, decking is normally permitted development if it meets the standard conditions.
What kind of deck suits a long 1930s garden in Eltham?
A deck close to the house for a level step out from the kitchen or living room, with the rest of the garden left for lawn and planting, usually works best. Tiers and steps suit gardens that fall away, and composite or hardwood both suit the scale.
Does slow-draining clay in Eltham affect decking?
It can. Clay holds water, so the subframe needs ventilation and a membrane underneath to keep timber dry. We check how your garden drains on the survey rather than assuming.
