Mixing up the ceiling levels give this apartment a loft-like, airy feel. Huge windows let in tons of light and a streamlined metal-and-wood staircase with lots of open space doesn't block sightlines across the room.

Choosing a few black accents like the stair railing and armchair gives crisp definition to the living area's open layout.

Brightly colored pillows and a rug give a vibrant splash of color to the living room, where silver and gray are the backdrop neutrals. The soft curved shapes of both the sectional and ottoman are family-friendly yet totally sophisticated choices.

This amazing living room is like stepping into a work of modern art with its bold primary colors and strong graphic shapes. White walls and black-framed windows add to the crisp effect.
