Pfeiffer House, Charters Towers, Heritage-listed residence in Charters Towers, Australia

Pfeiffer House is a single-storey timber building on low stumps, raised slightly on its northern side, with an exposed stud frame and an L-shaped plan. Verandahs encircle the structure, which stands on gently sloping land on Day Dawn Ridge.

Friedrich Pfeiffer, a German immigrant and mining magnate, built this house in 1881 near his Day Dawn gold mine during Charters Towers' gold rush period. The building stands for the expansion and prosperity that mine owners experienced in that era.

The house shows how wealthy mining entrepreneurs lived at that time, with details typical of the late Victorian period in northeastern Queensland. Its architecture reflects the wealth that gold mining brought to the region.

Pfeiffer House stands at 2–6 Paull Street on Day Dawn Ridge, on gently sloping ground; the timber building is raised slightly on low stumps on its northern side. It is a private church building, dedicated in 1983, so visits depend on the congregation rather than regular public hours. The site is reached from Paull Street in Charters Towers City.

The house is thought to be the oldest exposed-frame timber house in Charters Towers and among the oldest in North Queensland. When Frederick Pfeiffer died in 1903, flags flew at half mast and the Stock Exchange suspended its midday call for his funeral.
