Site tools

Aspect-aware design checks: DPC clearance, slope/gradient verdicts, outdoor step geometry and tree-to-foundation setbacks against UK best practice.

Site tools

Site-matched planting palette: filters a curated UK plant database by aspect, soil, hardiness and mood, then returns a layer-balanced shortlist, a year-round interest calendar and nursery-ready quantities.

Planting

Size a living wall or green facade: choose a system, check the saturated structural load, get planting density, automated irrigation sizing, an itemised bill of materials, an indicative budget and a multi-year cost of ownership.

Vertical gardens

Size a garden irrigation system from a bucket-flow test: converts supply flow into litres/min, applies friction loss, splits the system into hydraulically viable zones and returns a priced bill of materials.

Irrigation

Draw your area, mark the house wall and any focal feature, then get squaring numbers, balanced cuts, falls and a peg & string level schedule.

Site tools

Model the whole garden — draw every area, take levels and falls across the plot, and get garden-wide squaring, cut & fill and muck-away. Add extra areas for paths, lawns and beds.
