From the book The Architect Says: 

Each material has its own shadow. The shadow of stone is not the same as that of a brittle autumn leaf. The shadow penetrates the material and radiates its message.

Sverre Fehn: (1924-2009)

I’ll never look at my shadow the same way again.

Light is not something vague, diffused, which is taken for granted because it is always there. The sun does not rise every day in vain.

Alberto Campo Baeza: (1946 – )

I’m grateful the earth turns giving us both night and day and the transitions between.
