Future Americans will be living in smaller spaces and with fewer rooms. Formal living rooms are going extinct. Kiss the dining room goodbye as eat-in kitchens replace them. Separate rooms are also disappearing. Smaller-scaled furniture is overtaking built-ins and big pieces. Luxurious products such as spa showers, high-tech fixtures are on the rise. Master bedroom suites won't be bigger, just busier. Everyone's working at home. Remote control lighting and shades will be the new normal. Thumbs-down on swimming pools and hot tubs. Thumbs up on gardening and entertaining outdoors.
