Luxury is an extremely vague term. For some people, it relates to an aesthetic, while for others, it's overindulgence. But when it comes to interior design, we can all agree that "luxury" is actually a lifestyle. The concept of luxury interior design can be achieved through various styles, all of them bringing something new to the visual palate. However, there are a few key elements that are ever-present in all manners of luxurious spaces: grandness, spaciousness, and opulence. It's how you incorporate these ideas into your space that determines the level of luxury articulated in the designs.
