What does the land at
Diddly Squat Farm say?
An independent, two-minute terrain read of Jeremy Clarkson's farm — from 2 m LiDAR, satellite imagery, and a decade of climate data. Here's what the land itself says.
This property presents an unusually generous canvas: 385.4 hectares of cultivable, gently-graded land with a 3.6 million m² flat building zone and eleven natural water-collection points. It reads strong on terrain and growing area, tighter on climate (cool winters, 5 m/s mean winds), and balanced on water — adequate rainfall well-distributed across twelve months, but demanding storage thinking.
This property presents an unusually generous canvas: 385.4 hectares of cultivable, gently-graded land with a 3.6 million m² flat building zone and eleven natural water-collection points. The site reads strong on terrain and growing area, tighter on climate (cool winters, 5 m/s mean winds), and balanced on water — adequate rainfall well-distributed across twelve months, but demanding storage thinking.
Terrain & Building
The site spans only 90 m of elevation across its full extent, with a maximum approach grade of 0% — essentially level by rural-land standards, accessible by ordinary passenger vehicle year-round including in wet winters. The largest contiguous flat zone covers 362.8 ha, orders of magnitude larger than any single structure needs, giving near-total freedom in siting buildings, lanes, and infrastructure. Drainage from these pads is good — rainfall sheds rather than ponds. The 5.0 m/s annual mean wind, with a clear westerly prevailing direction and February peaks of 6.3 m/s, means orientation matters: shelter living spaces from the west, and plant windbreaks before pouring foundations.
“362.8 hectares of contiguous, flat, well-drained terrain — the constraint here is aesthetic and planning, not the ground itself.”
Water
Annual rainfall of 745 mm sits comfortably above the 500 mm threshold below which rain-fed agriculture becomes precarious, and — unusually — this site has zero dry months. October is wettest at 80.8 mm, April driest at 39.3 mm, but even April clears the threshold easily. This is a year-round-moist climate, not a Mediterranean dry-summer regime, which changes the storage calculus: the priority is buffering between wet weeks, not bridging a drought. Eleven viable pond/dam sites is an exceptional count — drainage convergence is concentrated and identifiable. The 18% moderate wet-zone coverage flags where building footprints should be avoided but where willow, alder, and wet-tolerant pasture thrive.
Sun & Growing
60.4% of the parcel faces south or southwest with minimal terrain shading — a strong orientation at this latitude. Solar resource averages 3.0 kWh/m²/day, modest by Mediterranean standards but realistic for a maritime climate; gardens get adequate light through the season and PV is viable if sized larger. The cultivable area (slope under 12°) covers 97% of the parcel at 385.4 ha. With 325 frost-free days and 887 growing degree days, the site supports apple, pear, plum, cherry, soft fruit, brassicas, root crops, and pasture; the GDD ceiling rules out heat-demanding crops. The clay loam (pH 6.7) is genuinely excellent — near-neutral, nutrient- and moisture-retentive without waterlogging, productive from day one. Build on it rather than rebuild it.
Climate Context
The temperature arc runs from a January average of 3.8°C to a July peak of 17.6°C — a cool-temperate maritime profile. Winters are chilly but not severe: about 40 frost days, concentrated in December–January, so hardy perennials (USDA zone 7–8) thrive but tender Mediterranean species need shelter. Drought risk is effectively zero. Humidity averages a high 85% across 147 rain days — a damp, soft-light climate where rain is frequent rather than torrential. Sunshine totals 2,882 hours, swinging from 374 hours in July to just 58 in December, so winter mood and any PV output both dip sharply mid-winter.
Risk Assessment
Fire. The EU JRC fire-perimeter archive shows zero recorded perimeters within the ~99 km² surrounding area over five years — a 0.00% annual burn rate, reinforced by zero dry months and a cool 17.6°C summer peak. This is a low-fire-load landscape; standard defensible-space management suffices. Flood. No formal flood mapping was sourced for this parcel — only terrain-derived signals. The 90 m elevation range and gentle grade drain adequately; the eleven convergence points mark where surface water concentrates and where footprints should be set back. An on-site hydrology check is recommended before construction.
Key Opportunities & Risks
Eleven viable pond sites combined with year-round rainfall make on-site water storage cheap and abundant — a rare combination. 362.8 ha of contiguous flat, well-drained terrain gives near-total siting freedom for buildings, infrastructure, and intensive cultivation. The dominant westerly wind (5 m/s mean, gusts to 8) calls for a deep-rooted windbreak along the western boundary (€20,000–€50,000 over a 3-year establishment). And the cool-temperate climate caps the crop list — plan for pome fruit, brassicas, pasture, and cool-season grains rather than Mediterranean staples.

On-site inspection is recommended before purchase or major development.
The layers compute the data; the maps make it readable. Every claim above traces to one of these. Read the note, then the map illustrating it.
The land as it actually is
A real aerial photograph of the farm — vegetation, bare ground, buildings, and water features exactly as they look from above. An honest first impression of the current state and land cover, and the base layer everything else is read against.
Where water collects, where it drains
Blue is where water naturally gathers; yellow and brown drain quickly. The blue areas are the best candidates for the eleven pond sites — keep buildings and septic out of them. Yellow and brown ground suits foundations and access roads.
The shape of the ground and the path of the rain
Contour lines over the satellite image, plus natural water-flow streams in blue. Tight contours mean steep ground; wide spacing means flat. The streams show where rain runs after a storm — for siting ponds, swales, and roads, and for knowing where not to build.
Terrain shape on its own
The same contour lines without the water-flow streams — a clean topographic read of ridges, valleys, and the gentle slopes you can walk. Pair it with the flow map to separate where the ground sits from where the water moves.
High ground and frost pockets
Elevation as a colour gradient from low (blue) to high (red). Low pockets catch cold air and runoff; higher ground drains well and catches the views. The full range here is just 90 m — gentle, rolling Cotswolds country with no dramatic relief.
How steep, and how buildable
Steepness across the parcel. Flatter ground is easiest to build and cultivate — here 97% sits under 12°, which is why buildability tops out at 100 and nearly the whole farm reads as workable cultivable land.
Which way the land faces
The orientation of each slope — the driver of sunlight and warmth. About 60% of the farm faces south or southwest, the favourable aspect for gardens, fruit, and any solar at this latitude. Place the kitchen garden and orchards on the south-facing mid-slope.
The landform, lit from a low sun
A shaded-relief render of the bare terrain — the land as if lit by a low sun, making the subtle rolls and hollows of this gentle ground legible. Useful for reading the lie of the land before you've walked it.
Sun, wind, and shelter in one view
Sun paths, prevailing winds, and terrain shading combined — the external forces acting on the land year-round. It shows where winter sun reaches, where the westerly wind hits hardest, and where natural shelter exists, so you can position the home and windbreaks where they matter.
The numbers that decide what grows
Rainfall, temperature range, frost-free days, growing degree days, and wind in one place. The frost-free window (325 days) and annual rainfall (745 mm) tell you more about productive potential than almost anything else on the farm.
