My House: Gallery Owner Francis Mill’s San Francisco Loft Is a Poetic “Place For Looking”

A wooden "curtain," designed by Mill and fabricated by John Hiser, divides the penthouse from the roof deck and redirects light. "I am obsessed with looking at these plywood forms at various times of day," says Mill, "from early morning at 5 a.m. to early evenings when the sun goes down. The light play is pure spatial poetry for me." A marble sculpture by Manuel Neri anchors the area.
