For many years now, open floor plans have been one of the most popular features in homes. The design is frequently incorporated in new home construction, and homeowners doing interior renovations might be eager to tear down a few walls to reimagine their space.

An open floor design works by having large, unimpeded spaces that can serve multiple functions. Lillian Custom Homes, a company in Waxahachie, Texas, says the most common use of an open floor plan is a "great room" that incorporates the kitchen, dining room, and living room in a shared space.

While compartmentalized designs are more common in older homes, the open floor plan is almost ubiquitous in newer homes. Donna Boyle Schwartz, writing for the home improvement professional Bob Vila, says the design first appeared in the 1950s, became more popular in the 1970s, and was heavily used in new home construction starting in the 1990s.

Despite this enduring popularity, there have been some suggestions that the changes brought by the COVID-19 pandemic might cause less demand for the open floor plan. Lisa Johnson Mandell, writing for Realtor.com, says the negative aspects of the design—such as a loss of privacy and amplified noise—have become more apparent as people attempt to work from home.

Whether you're searching for a new home or looking to overhaul your current one, you should be aware of both the benefits and disadvantages offered by an open floor plan.

Pros

By using columns and other supports instead of walls, open floor plans can maximize the square footage you have available in your home. Audrey Ference, also writing for Realtor.com, says that in addition to making the space feel larger, it also allows you to use it more efficiently. For example, you can set up a small dining space instead of relying on an infrequently used formal dining room.

This design also provides more flexibility in how you use the space. You might establish a traditional great room with a living room and dining area, or you could set aside a portion for an open game room or a workspace.

Having an open floor plan creates a more social space, which is great for entertaining. Lillian Custom Homes says the design allows you to chat with guests or family members while working in the kitchen. The longer sight lines also let you keep an eye on young children.

An open floor plan can create a better flow of traffic, allowing you to arrange furniture and other items while still leaving uncluttered routes to walk from one space to another. Similarly, natural light will not be impeded by any walls or doors, allowing it to travel farther and better illuminate the space.

The design naturally leads to less privacy, but there are solutions to temporarily set aside an area. Mandell says some options include hidden panels that can conceal a small office space or temporary partitions that can be removed as necessary.

The open floor plan doesn't need to be extended throughout the home, of course. The first floor might use this design to create a more social space, while the second floor will use traditional rooms to set up more private spaces.

Cons

An open floor plan allows guests and sunlight to make their way through the home unencumbered, but it also provides easy travel for less desirable things as well. Ference says sounds are less likely to be absorbed and more likely to echo, making the space noisier. If you don't have adequate ventilation in your kitchen, cooking odors will also permeate the living spaces that aren't walled in.

It's harder to conceal messes in an open area. Lillian Custom Homes says closed floor plans give you the option of simply closing the door on a cluttered playroom; you can't do that with an open floor plan. Schwartz says it's also easier for dust or dirt to be carried through an open space.

Those that enjoy cooking may find the process a little more difficult with an open floor plan. Appliances, prep spaces, and other kitchen features tend to be located farther apart than in a closed floor plan, so you'll have to walk farther while preparing a meal. An open floor plan also allows children easier access to kitchen hazards, and keeps any dirty dishes in the sink in full view of visitors.

Open spaces can be more difficult to keep comfortable, particularly when the design includes towering ceilings reaching up to the second floor. HGTV says fewer walls make it harder to keep heated or cooled air in the home, thus leading to higher energy bills.

If you have an extensive art collection, an open floor plan provides less space to display these works. Lillian Custom Homes says artwork can also be more vulnerable to damage in an open floor plan, since the additional natural light can be harmful to fragile pieces.

Walls can be a valuable feature for enhancing storage space. Schwartz says fewer walls means fewer opportunities for solutions like shelving, built-in bookcases, or console tables.

Converting an existing home to an open floor plan can be an expensive proposition. The support beams and columns need to be strong enough to be structurally sound, using costlier materials such as steel. HGTV says you'll also need to hire professionals for the important job of determining if walls are load-bearing and installing any necessary supports.
