Quarter-Acre Layout: Zones and Sun Mapping
Zones are about footsteps, sun mapping is about shadows. Together they decide 80% of a small-property layout.
Direct answer: Map the sun in three passes — 9am, noon, 4pm — at the spring and autumn equinox, then draw four zones by walking distance from the kitchen door. Put daily-harvest crops in zone 1, structures and perennials in zone 2, bulk storage in zone 3, and habitat in zone 4.
The zone system explained
| Zone | Distance from door | Visit frequency | Typical contents |
|---|---|---|---|
| 1 | 0–30 ft | Daily | Herbs, salad, tomatoes, tap, tool hook |
| 2 | 30–80 ft | 2–3 times a week | Main beds, berries, greenhouse, chickens |
| 3 | 80–150 ft | Weekly/seasonal | Orchard, storage crops, wood, bees |
| 4 | Edges | Rarely | Pond, native plants, brush, predator habitat |
Sun mapping step by step
- Print a simple site plan or sketch the lot to scale on graph paper (1 inch = 10 ft works).
- On a sunny day near the equinox, mark shadow lines at 9am, noon, and 4pm.
- Shade the areas that are shaded at each time in different colours.
- Mark "full sun" as anything with 6+ hours, "part sun" 3–6, "shade" under 3.
- Repeat once in midsummer — the difference between June and October shadows is often the reason a greenhouse underperforms.
Note the winter sun angle too. In the northern hemisphere at 40° latitude, the noon sun is about 26° above the horizon in December versus 73° in June. That low winter sun is what a south-facing greenhouse is designed to catch — and what a neighbour's evergreen will block.
Worked quarter-acre example
A 100 x 109 ft lot (10,900 sq ft), house on the north side, driveway east:
- South of the house (zone 1): 600 sq ft of raised beds, herbs by the door, a rain barrel at the downspout.
- South-west corner (zone 2): 10x12 greenhouse oriented east–west, berries along the west fence.
- West side (zone 2/3): chicken coop with a 200 sq ft run, compost bays behind it.
- North-east (zone 3): shed, wood store, root cellar barrel in the shaded slope.
- East fence (zone 3): four semi-dwarf fruit trees spaced 12 ft apart.
- North-west corner (zone 4): brush pile, native flowers, a small pond if drainage allows.
Notice what the layout avoids: no tall trees south of the greenhouse, no animals next to the neighbour's fence, and no storage that requires crossing the entire garden in winter.
Vertical growing on a small lot
When ground area runs out, go up: trellised cucumbers and beans on the north side of beds, espaliered fruit along fences, stacked pots for herbs. Vertical crops shade the bed behind them, so put them where that shade is welcome.
Frequently asked questions
How wide should paths be?
3 ft for a wheelbarrow, 18 inches for foot traffic. Main paths 4 ft if you will ever move soil or lumber through them.
Where should the compost go?
In shade, on level ground, reachable in winter, and not against a neighbour's boundary. Zone 2 or 3 is typical.
Do I need a full sun map?
Yes if you are siting a greenhouse or solar panels. A rough three-time shadow sketch is enough for a vegetable garden.
This is the detail behind the quarter-acre homestead plan. Next, decide bed type in raised beds vs in-ground, and see the book review for the land-plotting chapter this approach follows.
