The first thing to consider while on a journey to find the right kind of interior design style is to identify the purpose of an area.
Each corner of a house should be curated while keeping in mind the function or purpose it serves. Since you need to enjoy the spaces you often occupy, each element should meet a purpose. Some places are more straightforward like a bedroom for sleeping, a dressing room for dressing and grooming, while some areas like a reading room or a mini library need a little more effort.
As an example, every house has a living room and a bedroom, but in the end, it has to reflect the personality of the people occupying that space. Some people look for cozy comfortable reading corners, while some might be audiophiles. So, work on deciding the perfect color theme and overall feel of the room on what it will be used for the most.
