Original plans indicate that the sub-floor contained a generous L-shaped dining room, kitchen, scullery, pantry and servant's room; the piano nobile contained a drawing room and library (connected by folding doors) over the dining room, a boudoir and two bedrooms on the east side of the hall, and a main staircase off the vestibule to the west; and the upper floor accommodated 5 bedrooms and a bathroom. The three floor plans virtually replicated each other, and included a generous hall, wide, running centrally north-south on each level. Initially, verandahs across the whole of the southern and western elevations were intended, but only sections of these appear to have been built. In September 1888, Stombuco took out a mortgage of on Sans Souci from the Queensland Investment and Land Mortgage Company Ltd, of which Sir Arthur Hunter Palmer, Premier of Queensland from May 1870 to January 1874, was a director and principal shareholder. Even before Stombuco left Queensland in 1891, it appears that the mortgage company controlled the property, although Stombuco technically retained title until 1913. The house was clearly a rental property by 1890, at which time it was known as Palmerosa, and was occupied briefly (-90) by prominent Brisbane jeweller Lewis Flegeltaub, who had moved to Newstead House by 1891. Through the 1890s and early 1900s, Palmarosa was home to a number of socially prominent people and their families, including Joseph Bennett (possibly a Fassifern grazier) 1892-93; Reginald E Finlay (manager of the Queensland Investment and Land Mortgage Company Ltd) -97; Captain TM Almond (Queensland portmaster 1890-1902) in the late 1890s; and William Hood, MLA, in the early 1900s. From to , the principal occupant was Arthur Cecil Hunter Palmer, a civil engineer and second son of Sir Arthur Hunter Palmer. ACH (Cecil) Palmer and his wife, Lorna Barron, appear to have settled at Palmarosa within a year or so of their marriage in August 1902, and in 1913 title to the property was transferred to Mr Palmer. The Palmers were well known in Brisbane society for their race-day verandah parties at Palmarosa, overlooking the Albion Park Raceway, with "bookies" said to have visited the house to take bets. By 1932 the house had been divided into three flats, with the Palmers occupying the top floor.
