Alexandros Tombazis may have entered his eighth decade but, as we showed in our September issue, the Greek architect and eco-pioneer shows no signs of slowing down. He heads a 60-strong office in Athens and leads about 20 realised and conceptual projects per year. With more than 800 projects under his belt - about 300 of them built - and at least 110 prizes gained in competitions, he is one of Greece’s most prominent and successful living architects. Less known about Tombazis, however, are his skills as an artist. As he travels the globe, he is continually sketching, painting and taking photographs. Here he shows us a series of his energetic architectural drawings.

This sketch by Alexandros Tombazis depicts the interior of the vast church he built with local architect Paula Santos to accommodate the thousands of pilgrims that flock to Portugal’s Sanctuary of Fatima each year. Religious buildings, he says, are among his favourite commissions. ’Functionality in churches plays a role, of course, but much less so than in other projects. One has to focus on the atmosphere.’ The church was completed in 2007
