During the early reign of King Luís a new layout and decoration of the Palace rooms, entrusted to architect Joaquim Possidónio Narciso da Silva, followed the then recent standards of comfort, privacy and hygiene, typical of the 19th century bourgeois mentality. There was a demand for more intimate and sheltered spaces. The Ground Floor opens with a sequence of four rooms whiere, due to the official and private functions they were intended for, a significant amount of glamour was displayed, enhanced by the tapestries and allegorical paintings on the ceilings, remnants of the early 19th century decoration. From the Music Room onwards and running alongside the western facade, the Ground Floor was reserved for the private quarters. New chambers were introduced: a living room - the Blue Room -, the Dining Room for the family daily meals and leisure areas such as the Marble Room and the Billiards Rooms; and finally the bathrooms fitted with running water, hot and cold.
