This large, two-storey brick residence was built c.1904 to c.1905 for mining entrepreneur William Davies. Davies, who was involved in the gold industry in Gympie, moved to Brisbane around the turn of the century and purchased the Auchenflower site in 1903. Architect Claude Chambers, whose Brisbane work spanned fifty years, won a competition to design the residence known as Drysllwyn. The building was large and spacious with richly decorated main interior spaces. The ground floor contained dining, breakfast and drawing rooms, library, kitchen, bathroom, laundry and storerooms. On the first floor were located a main bedroom with dressing room and bathroom, two other bedrooms, another bathroom, a visitor's room and servant's bedroom. Verandas on two levels enclosed the building on three sides. The grounds contained a formal garden. During the 1930s part of the property was subdivided for residential development. The Davies family resided at Drysllwyn until February 1942, when it was leased to the Presbyterian and Methodist Schools Association for use by Somerville House as a day school. Somerville House had been forced to vacate temporarily their property at South Brisbane for use as administrative headquarters for the United States Army. In 1944-1945 the property was acquired by the Methodist Church, and converted into a hostel for country girls studying in Brisbane. The hostel was opened in August 1945 and the building renamed Raymont Lodge, in honour of Mrs E Raymont who had made a substantial bequest to the Methodist Church. The hostel was run under the auspices of the Central Methodist Mission. A parsonage for the Superintendent of the Central Methodist Mission was erected in the western corner of the property facing Cadell Street. By the 1960s a new dormitory wing had been added to house both male and female students. During the 1980s major changes occurred on the site with the Uniting Church relocating its state headquarters and Trinity Theological College sharing the grounds. A three-storey brick office building was erected at the rear of Drysllwyn and facing Bayliss Street. A new residential building was built to promote accommodation for tertiary students. Conservation work was undertaken on Drysllwyn during this period.
The college campus consists of two accommodation blocks and other facilities located in houses onsite, with the offices in the historic mansion Drysllwyn. This building, situated on the crest of a rise overlooking Auchenflower, is a large, two-story red brick residence built in the Federation style. The building has a half-gabled roof of broad profile, rolled edge iron sheeting with a projecting hipped bay to the northeast and southeast, a pedimented entry porch to the northwest and elaborately detailed chimneys. The building has deep verandas with arched masonry arcades and timber balustrade to the north, east and west. The entry porch is approached via a wide flight of steps and has paired columns to the first floor supporting the pediment. French doors with fanlights and step-out sash windows open onto the verandas. The timber-panelled main entry door is set in a large arched brick opening with stained glassfanlight and sidelights. A bathroom opening off the southeast veranda has a similarly elaborate doorway. The interior features decorative stained glass, ornate plaster mouldings and finely detailed cedar staircases, joinery, panelling and fireplace surrounds. The building is approached via a paved drive and turning circle from the northwest, with most of the recently constructed buildings being located to the north, east and south of the building leaving the Cadell Street aspect intact. The grounds contain a number of mature trees, with an in-ground swimming pool to the northwest. Although much of the site has been subdivided and sold for suburban housing, remnants of the original landscaping survive, as does a section of masonry perimeter fence, with iron entrance gates, which extends to the corner of Cadell Street and Park Avenue, returning along the latter.
