01 / The concept

An open story
of Asir.

The qasaba — the round watch and storage tower of the Asir highlands — returns to the city as a landmark at a busy junction on King Faisal Road. It is built the traditional way: hand-laid khalab mud courses, each protected by a projecting raqf slate ring that throws the rain clear, on a basalt base and three dry-stone terraces. Around it, a fragment of a qasaba wall with an old rifle and a granary with grain sacks tell of watch, harvest and home.

My role

All studies, the site layout, design development, the technical drawings and the BOQ (bills of quantities) for this project were prepared by Mohamed Bider for AMSY Group, with the visualisations and the night-lighting concept.

Studies.

The tower and its junction studied from the site layout to the build-up, the slate-course rhythm, the sightlines and the night lighting. Select a study.

Site layout — The approved Layout 2 on the junction: the qasaba on its three stone terraces in the main island, a stepped qasaba fragment with an old rifle on one side island, a granary with grain sacks on the other, and native grasses on basalt gravel in the medians.
05 / Materials & colours

& colours.

Everything comes from the mountains around Abha: basalt and granite for the base and terraces, khalab mud for the shaft, raqf slate for the rain courses, tamarisk and juniper timber for floors, roof and door, limewash and jute — and native grasses on basalt gravel.
