A turret on a house is a small tower that projects vertically from the wall of a building). It can occupy one or more stories and extend above the top story of the house. Turrets can be round, square, hexagonal, or octagonal, and they can have a circular top with crenellations, a pointed roof, or other kind of apex). They can be part of a room that can be simply walked into, and they might contain a staircase if they project higher than the building). Turrets were historically used for defense, as they provided a projecting defensive position allowing soldiers to attack from above). Nowadays, turrets are mostly used for architectural interest and can add a sophisticated touch to a house. Turret rooms can be used as a small office, reading nook, small kids playroom, or even a meditation space.
