Garden & landscape design studio

Gardens drawn for the ground they stand on

We survey the soil, the shade and the water before we draw a single line. Then we design the garden that site can actually keep alive — and stay with it through the build and the first two growing seasons.

  • Surveys & planting strategy
  • Detail drawings & schedules
  • Build oversight & aftercare

How we work with a site

Three lanes of work, and what each one hands over

Most gardens fail on drainage, shade or soil rather than on taste. Each lane below ends in something you own and can give to any contractor.

01

Survey & planting strategy

A measured read of the plot before design begins, so the scheme is built on conditions rather than assumptions.

  • Measured site plan with levels and boundaries
  • Soil texture and pH sampled at three depths
  • Shade mapping for midsummer and midwinter
  • Written planting strategy for each aspect
02

Design & detail drawings

The full drawing set a builder can price and work from, with every material named and every plant counted.

  • Layout plan with setting-out dimensions
  • Hard materials schedule and edge details
  • Planting plans with species and quantities
  • Lighting and water point positions
03

Build oversight & aftercare

We stay involved while the garden is made, then through establishment — the stage where most planting is won or lost.

  • Tender pack and contractor comparison
  • Site visits at each build stage
  • Planting day supervision and setting out
  • Two-year establishment and pruning notes

Process

From first walk-round to a settled garden

Design work takes weeks; planting takes seasons. Knowing the order helps you decide when to start.

  1. Stage one

    Walk-round on site

    We spend a long first visit on the plot: what you want from it, what already grows well, where water sits after rain, which views you want kept or hidden. You get a short written summary and a realistic scope before any fee beyond the visit.

  2. Stage two

    Survey, levels and concept

    Measurement, soil sampling and shade mapping come first, then a concept plan with a planting character for each zone. We present it on site where possible, so decisions are made looking at the real thing.

  3. Stage three

    Detail set and costings

    Setting-out dimensions, construction details, materials schedule and planting plans are drawn up and sent to contractors for pricing. If the figures land above your budget, we revise the scope here rather than thinning the planting later.

  4. Stage four

    Build, planting and establishment

    Hard work is built first, then planting goes in during the correct window for the species chosen. We return through the first two growing seasons to check establishment, adjust irrigation and set the pruning routine.

Gardens

Three plots, three sets of conditions

Described by site and scope rather than adjectives — the useful comparison is whether your plot resembles one of them.

Slender birch trunks rising from a green woodland floor in soft daylight
Woodland edge

Clay slope, north-facing

A heavy clay garden falling away from the house with almost no direct winter sun. We cut three shallow terraces, used the spoil to level a sitting area, and planted a woodland edge of birch, hellebore, epimedium and ferns that tolerates both wet winters and dry summer shade.

Scope
Survey, full detail set, build oversight
Key issue
Winter waterlogging at the slope base
Answer
Land drain to a planted soakaway basin
A sunlit meadow of pink and white flowering perennials seen at eye level
Open meadow

Exposed plot, thin topsoil

An open site with wind from two sides and only a shallow layer of topsoil. Rather than importing soil for borders, we leaned into the poverty: a sown perennial meadow with mown routes through it, a clipped hedge windbreak, and one sheltered gravel terrace.

Scope
Survey, planting strategy, meadow plan
Key issue
Wind scorch on new planting
Answer
Hedge planted a season ahead of the garden
Dense flowering border of purple and white blooms packed into a narrow garden bed
Walled courtyard

Small enclosed garden

A narrow walled courtyard with four hours of summer sun and dry soil at the wall base. Reclaimed brick paving, a single raised water tank and climbers on wires do the structural work; the planting is shade-tolerant and repeated in a short list so it reads calm at close range.

Scope
Survey, detail set, planting supervision
Key issue
Dry shade in the rain shadow of the wall
Answer
Raised beds with a drip line on a timer

Survey

Six things we measure before drawing

If a studio has not checked these, the plan is decoration. Use the list to question anyone you are comparing us with.

Soil

Texture and pH sampled at three depths in several places. Clay, chalk and sand each rule out whole plant families, and a single sample from one corner is not enough to design from.

Aspect & shade

Hours of direct sun per zone at midsummer and midwinter, including shade thrown by neighbouring buildings and trees. This decides where seating goes as much as what gets planted.

Drainage

A percolation test in the lowest part of the garden, plus a note of where water stands after heavy rain. Everything about levels, lawns and terraces follows from the result.

Existing trees

Species, condition and root protection area for anything staying. We set out paving and foundations around those zones instead of discovering the conflict mid-build.

Access

The widest clear route into the garden, surface by surface. It determines machine size, whether materials arrive by barrow, and a large part of the build cost.

Water & power

Existing outdoor taps, downpipes worth harvesting and any usable power supply. Irrigation and lighting are cheap to design in now and disruptive to add afterwards.

Season decides your start date, not the diary

Design can begin in any month, but bare-root trees, hedging and most perennials go in while the ground is cool and damp. Starting the survey in autumn usually means planting the same winter; starting in late spring usually means waiting for the next one. Tell us your hoped-for finish and we will work backwards honestly.

Questions

What clients ask before committing

Answers to the six questions that come up at almost every first visit.

How long does the design work take before a build can start?
For a domestic garden, allow roughly six to ten weeks from survey to a priced detail set, depending on how many rounds of revision you want and how quickly contractors return figures. Larger plots or anything needing a tree report take longer. Build length is set by the contractor, not by us.
Will the garden need permission or consent?
Most planting and paving does not, but raised structures near boundaries, significant level changes, work in a conservation area and anything touching a protected tree often do. We flag it at the walk-round stage and tell you what evidence an application would need before you spend money on drawings.
Do you build the garden yourselves?
No. We design and then oversee. Keeping design separate from construction means we can compare contractor prices on your behalf and inspect the work without a conflict of interest. We tender to landscape contractors we have worked with and are happy to include one of your own.
Can we use a contractor we already trust?
Yes, and it often helps. The drawing set is written so any competent landscape contractor can price and build from it. We ask for one pre-start meeting with them to walk through levels, drainage and setting out, then keep to the same site-visit schedule.
Is a small garden worth a full design?
Small gardens are less forgiving, not less complex — every mistake is in view from the house. For courtyards and narrow plots we often run a reduced scope: survey, layout plan and planting plan without a full tender pack, which suits a build by a single skilled contractor.
What happens after the garden is handed over?
You get a written establishment schedule covering watering through the first two summers, pruning in year one and two, and when to lift and divide. We return at agreed points in those two years to check how planting is settling and to adjust anything that is struggling.

Enquire

Tell us about the plot

A few details are enough to say whether we are the right studio and when a survey could happen. No obligation follows from sending this.

Enquiries are read in the order they arrive, and we reply either way — including when a plot is better served by someone else.
