He played an important role in the evolution of Gothic architecture in Portugal throughout the 15th and the early 16th centuries.
Huguet married Maria Esteves between 1436 and 1437 and was allocated a house and property near the monastery by King Duarte.
This points to a certain influence of the English Early Perpendicular style, as can be found in the nave and transept of the Canterbury Cathedral.
The main façade of the monastery has an original Portuguese style, a mixture of Rayonnant and Flamboyant Gothic design with strong horizontal lines contrasting with elements of English Perpendicular, that finds few parallels in Europe.
Master Huguet built the square Founder's chapel between 1426 and 1434 on orders of King João I to become the first royal pantheon in Portugal, a mausoleum for the Aviz dynasty.
The carved tracery decoration in Gothic style (including quatrefoils, fleurs-de-lis and rosettes) by Huguet in the ambulatory of the cloister of King João I now forms a combination with the Manueline style in the arcade screens, added later by Mateus Fernandes.
