These large windows radiate advanced style and appeal, as well as giving the interior a lighter, airier feeling. The most crucial features of a real Palladian window are a large central window with an arched top, flanked on both sides by smaller rectangular windows or "sidelights"
The majority of modern property owners are not interested in whether their window consists of the required columns or pilasters and entablature to certify it as a true Palladian window. This suggests that frequently, when someone speaks about a "Palladian window", what they indicate is something that has the standard functions like the main arched window with smaller sidelights on either side and even just a grand three-part window rather than anything more particular.
