What type of window is characterized by a smoother, rounder design compared to a bay window?

The correct answer identifies a bow window, which is known for its distinctive design. A bow window typically consists of a series of panels or sections that curve outward, creating a rounded appearance. This feature offers a more fluid and softer aesthetic compared to a bay window, which is usually more angular and consists of flat sections that project out from the house at distinct angles.

Bow windows not only enhance the exterior look of a building but also allow for more natural light and a wider view from the inside, as the curvature provides multiple vantage points. This architectural style is especially popular in residential designs to create a welcoming and spacious atmosphere.

The other options represent different types of windows or features that do not fit the description specified in the question. A clerestory window is typically placed high on a wall to bring light into a space without compromising privacy. A dormer window is a structure that protrudes from a sloped roof and usually has a vertical window below the roofline. A skylight is a window installed in a roof or ceiling that allows natural light to enter a space from above, but it does not have the rounded design of a bow window.
