The Glass Room by Simon Mawer

The Landauers, a recently married couple, commission German architect Rainer von Abt to build a modern house in Czechoslovakia. The Landauer House, based on the Villa Tugendhat, becomes a minimalist masterpiece, with a transparent glass room as its center. World War II arrives, and they must flee the country, with their happiness and idealism in tatters. As the Landauers struggle abroad, their home passes through several new owners, with each new inhabitant falling under the spell of the glass room.
