Timber decking is a popular choice across South London's period and contemporary gardens alike. - **Pressure-treated softwood** (typically pine or spruce) — the most affordable timber decking option; treated to resist rot, insects, and weathering; requires annual oiling or staining to maintain appearance and extend lifespan - **Hardwood decking** (such as Balau, Ipe, or Cumaru) — naturally dense, oil-rich timbers with exceptional durability and a rich, attractive grain; requires less maintenance than softwood; sourced from sustainably managed forests - **Accoya decking** — a high-performance modified timber with outstanding dimensional stability and rot resistance; an excellent choice for South London's variable climate Timber decking is particularly suited to gardens with a natural, informal character — cottage-style gardens in Wimbledon, rear gardens of Victorian terraces in Clapham, and family gardens across Mitcham and Sutton. ### Composite Decking The fastest-growing choice for South London homeowners seeking a beautiful deck without the ongoing maintenance commitment of natural timber. Composite decking boards are manufactured from a blend of recycled wood fibre and plastic, producing a material that is: - **Slip-resistant** — textured surface provides grip even when wet; an important safety feature for South London's rainy climate - **Fade-resistant** — UV-stable pigments maintain colour for years without fading or bleaching - **Splinter-free** — smooth surface safe for children and pets - **Low maintenance** — requires only an annual wash with soapy water; no oiling, staining, or treating - **Long-lasting** — quality composite boards carry 25-year or lifetime manufacturer warranties Composite decking is available in a wide range of colours — from natural wood-effect tones to contemporary grey and anthracite shades — making it suitable for any garden style across Croydon, Sutton, and the wider South London area. --- ## Decking Designs & Features Green Garden Construct LTD designs and builds decks in a wide range of configurations to suit any garden: - **Ground-level decks** — laid close to the ground as a patio alternative; ideal for gardens with good drainage and level or gently sloping ground - **Raised decks** — elevated above ground level on a subframe structure; ideal for sloping gardens or to create a level platform adjacent to a house with a raised floor level - **Split-level decks** — multi-tiered decking designs that follow the natural contours of a garden; create distinct zones for dining, relaxing, and planting - **Wrap-around decks** — extend along two or more sides of a property, maximising the usable outdoor space - **Deck with integrated steps** — steps connecting the deck to the garden below, or to different levels within the deck - **Deck with balustrade and handrails** — safety railings for raised decks; available in timber, glass, stainless steel, or composite to suit any garden aesthetic - **Deck with integrated lighting** — LED deck lights recessed into the boards or posts for atmosphere and safety in the evenings - **Deck with pergola or canopy** — combining decking with an overhead structure to provide shade and shelter — particularly popular in Wimbledon and Clapham gardens --- ## The Installation Process 1. **Free consultation and site survey** — the team visits the property, assesses the garden, discusses the client's vision and requirements, and recommends the most suitable deck design and material 2. **Design and specification** — deck layout, size, board direction, balustrade design, and any additional features agreed with the client 3. **Written quotation** — fully itemised with no hidden costs 4. **Groundworks and subframe preparation** — site clearance, levelling, and installation of the supporting subframe structure using appropriately treated timber or galvanised steel posts and joists 5. **Decking board installation** — boards laid to the agreed pattern with consistent, even gaps for drainage and thermal movement 6. **Balustrade, steps, and finishing** — handrails, steps, fascia boards, and any lighting or additional features installed 7. **Site clean-up** — all waste materials responsibly disposed of; garden left tidy 8. **Handover** — completion walkthrough with the client and maintenance guidance provided --- ## Planning Permission for Decking in South London Most residential decking in South London does not require planning permission under Permitted Development Rights, provided: - The deck is no more than 300mm above ground level (for decks over 300mm, conditions vary) - The deck does not cover more than 50% of the total garden area - The deck is not forward of the principal elevation of the property - The property is not in a Conservation Area or listed building setting Raised decks and decks in Conservation Areas may require planning permission.
