Kilcoy Homestead, a single-storeyed brick residence with a hipped corrugated iron roof, is located at the end of a ridge to the north of Kilcoy, overlooking Kilcoy Creek and surrounding farmland. The building, reflecting a strong Georgian influence in its design, is approached from the southwest via a
driveway along the ridge top. The building, L-shaped in plan, is constructed of English Bond brickwork and is surrounded by verandahs with the southern side being enclosed. French doors with shutters open onto verandahs which have unlined corrugated iron skillion roofs and timber posts. The main entry is positioned centrally on the northeast, with a set of brick steps accessing the verandah to a flat arched doorway with double cedar panelled doors with fanlight and
sidelights opening to the entrance hall. A matching doorway accesses the entrance hall from the enclosed rear verandah. The building's core is one room deep, with the northeast wing consisting of a central entry hall, a bedroom on the north, a living room on the south, store rooms at the southern end and brick lean-to store rooms at the rear. The rear wing has one large bedroom, an enclosed verandah on the south housing a kitchen and a brick lean-to at the rear housing a bathroom. Internally, the walls are plastered, the ceilings are boarded and skirtings, doors and
architraves are of cedar. The entry hall has unset sandstone flagging to the floor and other principal rooms have boarded floors. The two northeast rooms have fireplaces with timber surrounds. The kitchen and bathroom are later alterations. The southern store rooms have a loft space, and a basement wine cellar which is no longer accessible. The lean-to store rooms at the rear, one being the former lamp room, have concrete floors. The homestead grounds include mature
Bunya Pines, with other plantings of native and European trees. A terraced area to the northeast of the building may be the site of an early tennis court. The remains of a brick
shed is located to the southwest of the building. This consists of two side walls, the northern one housing a fireplace, with a freestanding
gable roof supported on metal posts. A former railway station building, titled WINYA and constructed of weatherboard with a corrugated iron gable roof, has been moved onto the site and is located between the homestead and the brick shed. A dairy and stables, constructed of brick and timber with a corrugated iron gable roof, is located further to the southwest alongside the driveway. == Heritage listing ==
