A desire for green, clean lines, pared down planting and symmetry around the central axis of a protected walnut tree gave rise to this simple uncluttered design. Space for a dog to roam and privacy from overlooking windows were further key factors. Also important was to make the drop in levels to the ground floor safe for children without loss of light from a barricade or planting. The glass panel balustrade together with a restricted species planting creates a serene relaxing space.
