A core of light powered by heliostat is a central feature of 3 Christou Lada Street in Athens.
I found it looking at works of Transsolar, which is apparently (not only) engineering company, which authored the introductory space of Arsenale in Venice Biennale 2025, called Terms and Conditions.
Transsolar literally specialize in engineering Sunlight, which is featured in almost every project they present.
Speaking of credits, the architects of this apartment building are DECA, who remain low key, and do not even present this work in their website (hopefully just too busy).
