“Three walls, hand-laid in a single rhythm, holding a hillside without ever raising their voice.”
N° 079 · Walls
A sloped backyard that had eroded toward a koi pond for fifteen years needed structural intervention without losing the character of the existing rock garden. We answered with three terraced dry-stack walls — engineered, but laid by hand in the spirit of an old stone wall in a Yorkshire fell.
Total grade change was 1.8 m over a 9 m run, and the lowest wall sat 1.2 m from the koi pond. Any sediment loss during construction would have killed the fish, and the pond could not be drained.
We sequenced construction from the top down, used silt fencing and straw wattle at every lift, and back-filled with 19 mm clear stone wrapped in non-woven geotextile so groundwater drains without carrying fines. Each wall steps back 75 mm from the one below.

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