In the Middle Ages rich people's houses were designed for defense rather than comfort. In the 16th century life was safer so houses no longer had to be easy to defend. Rich Tudors built grand houses e.g. Cardinal Wolsey built Hampton Court Palace. Later the Countess of Shrewsbury built Hardwick Hall in Derbyshire.
In Tudor Times people below the rich but above the poor built sturdy 'half-timbered' houses. They were made with a timber frame filled in with wattle and daub (wickerwork and plaster). In the late 16th century some people built or rebuilt their houses with a wooden frame filled in with bricks. Roofs were usually thatched though some well off people had tiles. (In London all houses had tiles because of the fear of fire).
