A gate in the fence to the north of the house, and its associated steps, has disappeared, as has a tennis court that used to exist to the west of the house. There is no sign of the 1870s underground brick tank, and its location is not known. The south end of the combined barn and shed to the southeast of the residence was flattened by a falling tree branch in a storm in 2007, and the roof has been reconstructed. The same storm removed the roof and verandah of a two-room single men's barrack located to the east of the garage, and the barrack was knocked off its stumps and was deposited to south. The roof of the former quarters for Aboriginal workers was also lost in the storm. On the east side of Monsildale Road approximately north-northwest of Kilcoy, Monsildale Homestead occupies undulating land within a loop of Monsildale Creek. Approaching along Monsildale Road, the view is dominated by the homestead's main house and associated outbuildings set within a backdrop of treed mountains, undulating fenced paddocks and lush river flats. The homestead complex consists of the main house, slab barn and shed, single men's barrack and former Aboriginal quarters. There are a number of striking mature trees in the house yard including jacarandas, silky oaks, pines and eucalypts. Monsildale Creek makes a wide loop around the property. A vehicle shed southeast of the barracks is not of heritage significance. The property is entered by a driveway to the west of the residence off Monsildale Road. Standing on a grassed knoll, the distinctive white-painted main house consists of the early 1870s core to the north and an L-shaped extension (c.1912) to the south. Timber framed and sheltered by hipped and gabled roofs clad with red painted corrugated iron, the house stands on low timber stumps. Once entered through the main entrance door to the north and organised around a central hall, the house now functions as a series of rooms operating off verandahs which run around the west, north and east of the house. A recently enclosed verandah to the south functions as an informal entrance. The early house comprises a living room, two bedrooms (northeast and southwest), study/library, box room and porch. A short hall links the early house with the extension. The extension consists of a bedroom, living room, office, enclosed verandah and a service wing of kitchen, bathroom, store, toilet and laundry.
