In residential terms, an open floor plan refers to combining a kitchen, living room and dining room. Many of these types of layouts have the walls eliminated, allowing continuity of space, and free access between the most-used areas of the house.

As you can see, the spacious layout allows for better arrangements of your mid-century furniture...

Community Time

Having all your main rooms in one section is a great way to have all the family members hanging out, chatting it up, debating political opinions, and interacting in a way that having separate rooms would otherwise make more difficult. Prepare your family a spectacular meal, within earshot of movie sound effects blasting from the 85-inch living room television.  

Throwing a party? Maximize the use of 3(or more) contiguous rooms to occupy more guests, set more plates, plan more "arts and crafts" nights...and have more fun!

Mid-century modern lighting can be tricky in these kinds of plans, so the right fixtures are crucial. Several sources should be arranged on the ceiling, so you can properly highlight all your important pieces.  

Shine Some Light on the Subject

With this much space to accent, strong and adjustable overhead lighting is necessary to balance out the glow throughout the whole floor plan. A series of suspended mid-century ceiling lamps work best for this effect. Designers like Poul Henningsenhave a portfolio of stylish lighting options for the ceilings, or other areas of the plan.

This open-floor plan has a very modern feel to it.

Don’t Waste the Space

Think about the different views you have in the house, and how to accentuate them in the best way the floor plan allows. Allow for as much natural lighting as possible, and wide enough paths between furniture pieces, for foot traffic.

There are a few setbacks to having an open floor plan, that wouldn't normally arise in other layouts.

Extra Noise

Because of the acoustics laden in large rooms with higher ceilings, the noise tends to carry further. If there’s a lot of activity happening simultaneously, than it could get a little noisy.

Under the Microscope

There’s not as much alone time because of the open-ended rooms. This could be a good or a bad thing depending on the type of people involved. Try to keep some other areas in the house sectioned off to avoid living in a complete fishbowl.

Score one for Storage

Three rooms in one area, usually eliminates individual spots for storage that wouldve been there in a normal floor plan. Combat this setback with areas like hidden shelves, intelligent use of storage cases, and other nifty ways to save space.

Air Ventilation

The aromas from the cooking area can linger to other areas of the house, so keep a fan or exhaust system to keep the airflow moving freely about the premises. The above points sum up the benefits and problem areas you might encounter when deciding if an open floor plan is right for you.
