Sustainable composite decking with pergola and garden seating

Garden design specialism

Sustainable composite decking, quietly engineered.

Decking that performs like timber but doesn't rot, twist, or splinter. Specified for private gardens across London, Kent, and the Home Counties, installed by the studio's own carpenters.

What this is

A softer hand than hardwood, the same working life.

Composite decking is a co-extruded board of recycled hardwood fibre and virgin-grade polymer. Finished well, it reads as timber. The deep graphites and warm umbers of a British hardwood, the tooled edge, the long plank. Walked on, it feels the same.

Where it earns its keep is in what it doesn't do. It doesn't rot at the joist line after seven years. It doesn't silver unevenly under London soot. It doesn't need re-oiling every spring. For a garden built to last a generation, it is the quietest decision on the plan.

How it works

Four steps, carried out by the studio's own team.

01

Site survey

We measure the footprint, assess drainage, and confirm structural support. Every project begins with the ground, not the board.

02

Joist & substructure

Adjustable aluminium pedestals or pressure-treated timber joists, set dead-level, with concealed drainage below. The substructure earns its keep out of sight.

03

Board laying

Concealed T-clip fixings throughout — no visible screws. Boards are cut on site with a mitre-sled jig to keep the end grain square. Edge trims in matched composite.

04

Handover

A simple care sheet (there's very little required), the manufacturer's warranty documents, and a twelve-month studio-side review booked in the diary.

Questions

Questions we're often asked.

Is composite decking actually better than hardwood?

For most private gardens, yes. The capped polymer face resists water, UV, and foot traffic, and doesn't need the annual oiling that keeps a hardwood deck looking right. Hardwood is still the beautiful choice for a few very specific settings (covered verandas, show gardens). We will tell you which is right for yours.

Does it get hot underfoot?

The lighter tones stay comfortable in UK summers; the darker grades (graphite, charcoal) can run warm in July sun for a few hours, as any dark surface would. If you're barefoot-garden-first, we steer towards the mid and warm tones.

How does it age?

Uniformly. Unlike timber, which silvers unevenly where rain lands differently, composite holds its tone for the life of the warranty. The surface picks up a soft patina over the first year, then stays stable.

Can it be installed over an existing patio?

Yes, in most cases — pedestal substructures sit straight on concrete or paving and give us a level finish without breaking out the existing ground. It saves a week of groundwork and a skip of hardcore.

What is the cost like to commission?

Supply and fit varies with substructure type, the board specified, and the edge detailing. On any commission the figure is itemised in the design proposal, with no margin on margin and no hidden extras. We share it once we have walked the site and understood the brief.

Do you install composite decking as a standalone job?

For existing clients, yes. For new relationships we prefer to include it as part of a broader design — the terrace sits within the planting, the steps sit within the paving. Composite decking is a material, not a product; it benefits from the same consideration as the rest of the scheme.
