Artwork recordThree views of one material idea.
Sana’a’s old city is known for its many-storeyed tower-houses and long history as a religious and political centre. Repeated vertical dwellings form a dense urban fabric within a mountain valley.
Read the material study01 / Reading the material
A house in the skyline
Sana’a’s tower-houses connect stacked openings with a dense collective roofscape. A single dwelling has a vertical rhythm, while several together establish a larger urban field. The material reading moves between those scales rather than treating the skyline as one decorative silhouette.

02 / From surface to space
Read the whole.
Then the edge.
Compare the repeated openings high on a facade with the narrow street below. The change in viewpoint makes the building’s height tangible. Shared proportions and repeated verticals can hold the ensemble together while individual houses retain their differences.
Compare a tower-house’s stacked openings with the narrow street below. How does vertical repetition create both an individual house and a collective skyline?

04 / At the bench
Make the observation tangible.
Compose several original narrow fronts with a consistent vertical rhythm and modest variations in height. Test the group from near and far. Keep particular ornamental motifs and historical claims attached to documented buildings rather than inventing them.
Keep a view of the whole beside a close detail. Note the material, lighting and the one variable you changed.
