On his return in 1537 from a study in Rome, Bullant worked for Montmorency, for whom he transformed the Château d'Écouen about 1550, built the "petit château" at Chantilly, and modernized the Château de Fère-en-Tardenois, with its splendid bridge.
His treatise on architecture, La Règle générale architecture sur Les cinq manières de colonnes, was published at Paris, 1564 and 1568. Bullant was also the author of treatises linking theory to practice, on geometry for craftsmen (Petit Traicté de géometrie et horologiography pratique, 1564), and horology, notably quadrants and solar clocks (Recueil d'Horlogiographie, 1561).
