Your garden, considered

A better connection between home and garden

A deck can create a dining area by the kitchen, level out a sloping garden or turn an awkward corner into a seating spot. What makes it last is the frame underneath: joist size and spacing, fixings and ventilation.

We help you compare timber and composite boards, plan the layout around doors and steps, and build on a properly supported, ventilated frame.

For Westminster terraces and courtyards, low-profile composite decking can sit over existing surfaces where drainage allows.

Materials & possibilities

Timber or composite?

Both can look excellent. The choice is about maintenance, feel and budget.

Softwood timber

Natural and affordable

Pressure-treated boards that need regular cleaning and oiling.

Hardwood timber

Rich and durable

Dense boards with a longer life and a premium look.

Composite

Low maintenance

No staining or sanding; colour stays consistent for years.

Steps & seating

Built in

Steps, benches and planters designed into the frame.

It is the frame that matters

Most failing decks are let down by the frame: undersized joists, poor fixings or no ventilation. We build on treated joists at the right spacing with airflow underneath, so the boards stay flat and secure.

Decking in Westminster: your questions

Still deciding? Tell us about your garden and we can talk through the next step.

Read our warranty terms

Do I need planning permission for decking in Westminster?

Not usually, if it is under 30cm high and covers less than half the garden. Raised decks may need permission.

How long does composite decking last?

Good composite boards typically carry long manufacturer warranties and need little more than washing.

Can you replace boards on an old deck?

If the frame is sound, yes. If joists have rotted, we recommend rebuilding the frame.

How long does a deck take to build?

Most decks take two to five days, depending on size and steps.

Do you cover all of Westminster?

Yes. We work across Westminster (SW1), including St James's, Pimlico and Victoria, and nearby areas such as Victoria and Pimlico. Our base is in Norbury, SW16, about 6 miles from Westminster.
