A patio that defers to the trees it lives between, dry-laid so the rain returns to the soil that grows them.

01Overview

The clients — both architects — had inherited a tired stamped-concrete patio that fought their otherwise contemporary backyard. The brief was simple: make it disappear into the landscape. The answer was irregular natural flagstone, dry-laid, with joints wide enough for creeping thyme.

02The Challenge

Salvaging two mature maples at the patio's edges meant we could not over-excavate near the drip lines. Air-spade work and a custom raised perimeter were the only way to preserve the canopy the courtyard depended on.

03The Approach

We air-spaded a 600 mm buffer around each root flare, brought in 150 mm of structural soil at the edges, and dry-laid hand-selected limestone flagstone on a permeable open-graded base. The thyme will fill the joints by year two.

Every Anissa Inc. project begins the same way: a quiet walk of the property, a measuring tape, a sketch.
