An effective interior design aims to create spaces that enhance comfort and usability, which is vital in making environments more livable and functional. When an interior design is executed successfully, it considers user needs, aesthetic preferences, and the practicalities of the space.

This leads to improved comfort as it accommodates how people interact with their environment, promoting relaxation or productivity, depending on the intended use of the space. For instance, using appropriate furniture scales, lighting, and materials contributes to an inviting and efficient atmosphere.

Additionally, effective interior design can adapt spaces to better serve their intended purposes, whether that's creating a cozy living room, a productive workspace, or a calming bedroom. This alignment of design with the user’s needs underscores the importance of usability in any well-considered design project.

In contrast, the other options imply negative outcomes or misalignments with the primary goals of interior design. For example, a decrease in space functionality or an increase in design complexity detracts from the overall experience. Similarly, a reduction in property value contradicts the essential aim of enhancing space through thoughtful design choices. Hence, the improvement of comfort and usability encapsulates the desired impact of effective interior design succinctly.
