Hi,Alex Generally they have very similar meaning in Chinese speaking. But sometime if you want to go a little deep when you express,here I have something for you to take references: 'beautiful girl': 美 mei3 丽 li4 的女孩 (for expressing that this girl looks pretty, and also she is respectful as a person) 'beautiful house': 漂 piao4 亮 liang0 的房子 (for expressing that it is a nice house and it looks good) Thanks for reading my long wrote answer,hope it can help a little. Helen

They're same meaning.you can say "漂亮（piao liang）/美丽（mei li）/好看（hao kan）的女孩/房子。
