From the work of the architect and theorist Christopher Alexander: the fifteen geometric relationships that more often than not occur in structures that are whole, beautiful and alive.
Alexander’s theories, especially the late work he published in the four volumes of The Nature of Order, are being integrated into practice through the pedagogy and hands-on construction work underway in Sorrento, Italy at a new school called Building Beauty. TUG co-founder Dan Klyn is on the teaching and administrative staff of the school.
