All houses are unique. Even if they look the same from the outside, they are very different on the inside. I think houses are very interesting. I like looking at the way they are built and the style they are built in. In London there are many houses that are hundreds of years old. These are beautiful. You can still see much of the original wood and stone structure. Modern houses are also interesting. It’s funny how they copy many of the features of older houses. I love looking at houses when I travel. Every country has its own special designs, from Japan to Arabia to Greece. Nowadays people are building eco-friendly houses. They want houses that save energy and help protect the planet.
