Driveway Studio — plan, grade & section

Aerial photo & scale

Search your address to load LINZ aerial imagery with the scale set automatically — or screenshot your site from a maps app (top-down, zoomed in), upload it, then click the two ends of something you know the length of (a fence line, the house frontage, a parked car ≈4.5 m).

Sketch & landscaping

With no tool active, tap a building, pool, fountain or garden bed on the plan to select, rotate, or remove it.

100%

Upload a photo to begin. You can sketch without one, but set the scale first so quantities are real.

Stations & levels

Stations are generated along your sketched centreline. Enter existing ground level (EGL) at each station, then set design finished levels (FL) — or set FL at the first and last station and auto-grade the rest at a constant gradient.

Station	Chainage m	EGL m	FL m	Grade %	Cut / Fill to subgrade

Getting levels with your phone camera: browser pages can't reach ARKit/ARCore depth data, so this concept tool takes levels by hand. Fastest field method today: your phone's Measure app (iOS) or Google Measure-style AR apps — drop a point at a reference peg, read vertical offsets at each station and type them in here. Datum can be arbitrary (e.g. call the garage floor 100.00). Since you already build AR boundary-viewing experiences, the native path is straightforward: an ARKit raycast against the detected ground mesh (LiDAR devices give ±2–3 cm) captured at each station, exported as chainage/RL pairs — this page's data model (chainage, EGL, FL) is designed to accept exactly that.

Earthworks & materials

Item	Depth	Volume m³	Approx. tonnes

Volumes use the average-end-area method between stations across the full formation width (driveway width + batters), with a 10% compaction/waste allowance on imported material. Cut volume is bank (in-ground) measure — bulk it up ~20–25% for truck loads. Concept-level numbers only: confirm with a site survey before ordering.
