Answer : There really is no one definitive answer to this question as modern house design can mean so many different things to different people. However, in general, modern house designs tend to be clean and minimalistic, often making use of geometric shapes and lines. They can be highly functional and Scandinavia-inspired, or they may take a more traditional approach with a focus on natural materials and organic forms.
One common feature of modern houses is an open floor plan, which creates a spacious and airy feeling. Large windows are also often used in order to let in plenty of natural light. Modern houses can be built in a variety of different styles, so it really depends on what you are looking for in terms of aesthetics.
