The Ruby garden sits on a major axis and on three sides has gardens at a higher level. Large footings were constructed entirely around the garden to retain the soil of surrounding gardens and to support the Arch at one end and a set of stairs at the other. Agi drains were put in place, irrigation and water pipes laid and soil brought in. A complex piece of false work was fabricated in order to construct two intersecting arched ceilings inside the Arch itself. Once the walls were all rendered the plants were introduced and pebbles used for the pathways.
