Remember that an extremely unique design may reduce your ability to attract customers to your vacation home.
A unique design can appeal to some users as an attractive property. On the other hand, there is a risk of overly limiting the number of people to whom it appeals.
It is said that it is good to design the interior space like a famous movie scene, but for example, a vacation home that is designed to be cute for women with children may be difficult for adult men to use.
By unifying simple colors and decorating some of the interior walls with little or no decoration with a few unique paintings, you may be able to impress users with a sophisticated interior design.
