Pairing clean architectural lines with well-edited furniture is the greatest key. Though modern style has gone through its phases (glass brick, anyone?), distinct elements such as strong lines and simple materials have always been its hallmark.
Go with modern furniture that has already withstood the test of time. Who can ever see this Eames chair and ottoman becoming passé? Often one focal piece is all it takes to make a room.
Keep it simple. For a modern style that can withstand the aging process, understatement is key. Go for smooth, chic, and for items that stand out with a timeless style (check out the floor lamp!) rather than as a current trend.
Mix your mediums. This large surface coverage of wood finish (popular in the mid-20th century) pairs well with a more industrial look of steel. The open shelving adds a personal touch.
Similarly, this sleek dark kitchen finish pairs well with the lighter flooring and the various materials throughout. Keeping materials mixed and honoring materials that have been fresh and modern through the years creates a unique look for YOUR version of modern.
Take older, beloved furniture and arrange it in a more modern way. You don't have to have all of the latest modern furniture to suggest a modern space; in fact, acquiring all of the newest material of right now is exactly what will date your space. The sparseness and fresh arrangement of the furniture here pairs beautifully with the simple architecture and window detailing.
Keep the dramatically individual pieces to what can be interchanged somewhat easily. Here in this open and beautiful space, the chairs and table create a more understated look of modern, while the chandelier above makes a current statement.
Similarly, the pieces in this open dining and living room are solid, simple, and beautiful. The details in the art, lighting and decor could all eventually be replaced to create an entirely new look should the individual's style change.
Mixing things up a bit can add individuality. It can also string time into one continuous stream, breaking down barriers in past, present, and future. In a way, this room could have existed in the forties as much as next year. Classic pieces like the ottoman are arranged in surprising ways, and the mix of items blends into one great whole.
Modern materials such as this lacquered concrete flooring and center wall pair with classic brick, sculpture, and a classic lounge/salon setup. Who could ever see this open and intriguing space fading into oblivion?
In the bedroom, simplicity equally reigns. Neutrals create a quiet and consistent palette throughout. The window walls are framed with an understated light hue. And one signature piece overhead gives the space added individuality.
