The Rammed Earth Podium
Six hundred millimetres of compacted local aggregate, laid in visible lifts, grounding the tower in its own geology.
The podium walls were rammed on site in 150 mm lifts using excavated material from the foundations blended with regional clay and a low fraction of stabiliser. The striations record the sequence of work — a calendar of the build left in the wall.
Thermal mass does the quiet work. The podium holds overnight coolth and releases it through the civic floors during the day, flattening the peaks that would otherwise demand mechanical cooling.
Bronze reveals mark the entrances. Everything else is left raw, unsealed, and allowed to dust and darken where rain touches it.
