All "normal" stairs, windows, roofs, tables, chairs look the same. There are good reasons for stable architectural patterns. There are good reasons for web design patterns too. Go back to the 90's and early 00's. There were so many different styles. A few won and became the ancestors of today's styles. Many more lost and got extinct. Sure, there are other styles that nobody thought about that are better than what we have today. They'll get created from time to time, copied and refined.
