Restoring your own grandfather's building. What can we learn from the legacy of the Narkomfin building in Moscow? Clem Cecil talks with the building's chief restoration architect Alexei Ginzburg about Narkomfin, the building designed by his grandfather Moisei Ginzburg, one of the leading members of the Constructivist group. Alexei and his wife Natasha recently published in facsimile, the English translations of Moisei's books about architecture: 'Rhythm in Architecture' and 'Dwelling'.
