If you are thinking about redesigning your garden, one of the first questions is usually cost. The answer depends on how large your space is, how you want to use it, and how much change is needed. Every garden is different, but some clear guidelines can help you plan.

At Patchworks we design gardens across South London and coordinate their planting and construction with trusted contractors. Our aim is to create gardens that feel good to live with, not just look good on paper. Below is a straightforward guide to how garden design costs usually break down.

Design fees

Design work is charged as a fixed fee, agreed before anything begins. A complete design typically includes a site survey, concept layout options, a developed masterplan, a planting plan and outline cost estimates for the build.

Most complete garden design projects start from around £1,500 plus VAT, with the final fee depending on the garden’s size, complexity and the level of detail required. Larger or more complex gardens are quoted individually.

Not every garden needs the full package. Depending on where you are with it, the work might be a one-off consultation, a planting-focused design, a complete garden design, or a complete design with coordination through the build and planting.

I ask for half on booking the brief meeting and survey, and the balance once the final design is approved. Fees don’t include outsourced topographical surveys or structural engineers where these are needed.

Build costs

Build costs vary according to access, materials and complexity. As a general guide:

  • Simple redesigns with new paving and planting: from £15,000 to £25,000
  • Full redesigns with terraces, walls, lighting and planting: £30,000 to £60,000
  • Larger or complex gardens with level changes or bespoke features: £60,000 to £80,000 and above

Good design allows you to phase work or focus on key areas first if needed.

Planting

Planting is where design comes alive. It adds character and structure, and brings texture and colour through the seasons. Planting projects, including soil preparation and installation, usually range from £1,500 to £8,000, depending on size, density and the level of detail. Each plan is tailored to the site and designed for long-term interest rather than short-term effect.

Lighting and irrigation

Lighting adds a bit of atmosphere while irrigation helps with maintenance.

  • Lighting systems start from £1,200
  • Irrigation systems start from £800

Both can be installed during the main build.

What affects cost most

  • Access and ease of delivery
  • Material choice and finishes
  • Level changes and retaining walls
  • Additional services such as lighting or irrigation

A good rule of thumb

Many London gardens sit comfortably within a budget of £20,000 to £60,000 including design. As a guide, investing around ten to fifteen percent of your property’s value in the garden often adds equivalent value to the home itself.
