Hi. My name is Leah, I'm an architecture graduate with two years working experience. Looking at your requirements, I guess you are looking for a luxury minimalist design. The minimalist living room is planned with basic tone which is the brown, beige, grey, black and white. The customized full height cabinet and full length tv console cabinet makes the basic looks luxury. The wood partition wall is added behind the dining area to create a small space for your treadmill. It can be modified into any other function such as study room or home office. The living area is filled with kids friendly furniture with no sharp corners. A large, prominent wall art placed at the dining area to make the space a main area in the house.
