Expensive to Build
Open floor plans don’t have interior walls for support, and therefore the supporting beams have to be heavier or made of steel, which can increase the overall construction cost.
With an open floor plan, whether you’re in the living room, kitchen, or dining room, everyone knows what everyone else is doing. Privacy becomes a rare commodity when every nook and cranny is within someone's sight line.

Cooking in Full View
Some people may consider cooking to be a spectator sport, but most prefer to do their food prep out of view of their guests. Whether it’s making last-minute adjustments to seasoning or wiping down the edges of the plates before serving, most cooks have their little idiosyncrasies that are better performed in private.
You may love the aroma of ginger and cumin while you’re whipping up a batch of tikka masala, but you probably don't want those smells settling into your sofa upholstery. And no one likes to be reminded of last Friday’s fried fish!
More Work in the Kitchen
Open concept kitchens are typically less efficient for cooking. The sprawling design makes the cook take more steps to get from the fridge to the food prep area, and more again from the prep area to the stove, which means that cooking becomes a little more difficult and time-consuming.
Access to Kitchen Hazards
One argument often used in defense of the open floor plan is that it allows parents to prepare meals and keep an eye on the kids at the same time. Open plans also, however, make kitchen appliances, scalding water, and scorching-hot pots and pans much more accessible—and dangerous—to children.
More Visible Messes
You may not always feel like doing the dishes right after a big family meal or a blow-out bash with friends. But with an open-plan design, all of those dirty dishes, grimy glassware, and stale crackers are right out there for everyone to see until you get around to cleaning up and putting everything away.
The acoustics in an open floor plan can be a real nightmare. Sounds from the kitchen—the dishwasher, blender, and food processor—invariably spill over and intrude on the television or stereo in the living area.
Cold, Not Cozy
Huge open spaces can be cavernous and cold, more reminiscent of a gymnasium than a home. In fact, the open floor plan is practically the opposite of cozy.

Less Wall Space for Artwork
If you like to display paintings, photographs, or other artwork, you need wall space. Without interior walls, you have fewer places for wall hangings or other decor.
Less Storage Space
Fewer walls also means that you have a lot less space for console tables, bookcases, or shelves, which translates into less overall storage space.
Less Energy Efficient
Larger spaces are more costly to heat and cool, especially those with cathedral ceilings, which are featured in many open floor plans. As well, open floor plans cannot be split into HVAC zones, so you wind up paying to heat and cool the entire area rather than just the occupied spaces.
No Dedicated Rooms
Open floor plans don’t allow for specific, dedicated spaces for favorite hobbies or pastimes like crafts, sewing, woodworking, or reading.
The open floor plan is a hallmark of contemporary architecture, so it doesn't really fit with traditional furniture and decor. If your tastes run to colonial, Victorian, or Georgian furnishings, skip the open concept.
Hard to Keep Clean
Open spaces are by definition open, so they are harder to keep clean. Messes are tracked from room to room, kids' toys seem to multiply to fill the available space, and pet hair goes everywhere. Individual rooms are easier and faster to clean, and they also have doors to control—and conceal—messes.
Room for Improvement
Though it's got a lot of advantages, an open floor plan is not for everyone.
