Which type of house is characterized by ornate details and asymmetrical designs, often found in the 19th century?

The Victorian house is characterized by its ornate details, intricate architecture, and asymmetrical designs that emerged during the 19th century. This style is known for its decorative trim, vibrant colors, and varied rooflines, which often include gables and turrets. Features like bay windows, wrap-around porches, and intricate woodwork are also prominent in Victorian architecture, showcasing the craftsmanship of that era.

In contrast, Colonial houses typically represent a more symmetrical and straightforward design, focusing on simplicity and function rather than elaborate ornamentation. Contemporary houses are rooted in modern design principles, emphasizing clean lines and minimalism rather than the ornate detailing that defines Victorian styles. Lastly, a Modern Single Story house represents a more streamlined and pragmatic approach to design, moving away from historical styles and instead adapting to contemporary living needs and aesthetics. Therefore, the distinctive features of the Victorian house make it the correct answer in this context.
