A Closer Look at the Big House Trend

Large homes dubbed “McMansions” were once extremely popular. These spacious homes on small plots of land in the suburbs fell out of fashion after the recession in 2008, caused in part when an overinflated housing market burst. But the downward trend didn’t last long, even with the growing popularity of small-scale houses like cottages and tiny homes.

In the second quarter of 2024, the average size of a new home in the U.S. increased slightly was 2,164 square feet. McMansions can be anywhere from 3,000 to 6,000 square feet or larger.

When the COVID-19 pandemic hit, larger homes, especially in rural areas with outdoor amenities like swimming pools and patios, were in high demand. As more people were forced to work from home and go to school remotely, home offices and play space became especially desirable attributes in a house. In addition, owning a large home, especially with a low-interest rate mortgage, may translate into a profitable sale.

But buyers have found pros and cons to their decision to go big.

The Rise of McMansions

Starting around the mid-1990s, the average square footage of newly-built homes grew by leaps and bounds. By the time U.S. homeownership had peaked at 69.2% in 2004, a 3,000-square-foot home was considered on the small side when it came to new construction.

These giant new homes earned the nickname “McMansions” because they were often generic in style, packed in close together on postage-stamp-sized lots, and mass-produced—much like the fast-food delivery style the name suggests.

The derogatory nickname didn’t hurt their popularity. Not only were houses getting larger, but everything inside them got bigger as well. In 2004, around 40% of new homes had nine-foot ceilings rather than the standard eight-foot height.

Multiple heating, ventilation, and air-conditioning systems became commonplace. Two- and three-zone heating systems were a standard feature.

Furnishings also became super-sized. Consumers were buying everything bigger to fill their mini palaces, from professional-grade stoves and refrigerators to overstuffed, oversized sofas.

What Drives the Big House Trend in the U.S.?

Various factors drive the trend of buyers purchasing large homes.

New construction and the development of sprawling houses attract families who can afford to have the luxury of space and amenities.

Years of record-low interest rates, aggressive marketing of upscale homes by residential builders, and the coronavirus pandemic made larger houses even more popular with buyers.

What You Get with a McMansion

Big houses are all about interior space. The rooms are big, the ceilings are high, and the “wow” factor is, too.

The amenities that convince people to go upscale include lots of windows, spacious foyers, huge staircases, garages for three or four vehicles, gourmet kitchens, sunrooms, walk-in closets, and enormous master bedroom suites complete with whirlpool tubs and separate showers.

Walk-in pantries, laundry rooms, media rooms, and home offices also make the list. Over-sized garage doors (to accommodate oversized vehicles), gas fireplaces, and large decks are common must-have features.

What You Don’t Get With a McMansion

The tradeoff for a luxurious interior often comes at the expense of the exterior. Cookie-cutter designs, tiny lawns, close-packed lots, and garish designs that feature garages nearly as big as the homes are common features of the suburban McMansion.

Expensive brick or stucco on the front of the house with vinyl siding on the sides and back are signature design features, putting an elegant face toward the street and cheaper coverings elsewhere.

On the inside, open floor plans that include rarely-used formal living and dining rooms are par for the course.

While grand looking, large windows, high ceilings, two-floor great rooms, and huge foyers result in very inefficient—and expensive—heating and cooling. Furthermore, restrictive community associations often limit the ability to add personal touches to the front lawn.

McMansion Backlash

Not everyone loves a McMansion, and from Los Angeles to the Hamptons in New York, angry neighbors, zoning boards, and politicians have fought back against the oversized homes cropping up in established neighborhoods.

Starter homes and small ranch houses are being demolished and replaced by faux estates on quarter-acre lots as affluent people want to move closer to the city but don’t want to live in the smaller, older houses often found there.

To critics, these new homes look out of place compared to the rest of the neighborhood and clash with the existing architectural styles of neighboring properties.

Tips to Follow If You Decide to Go Big

The Right Location

A home is likely to be the most expensive item you will ever purchase. If you are contemplating a move to a larger home, pay attention to the details.

It starts with choosing the right location. Purchasing a property in a neighborhood with homes of similar size and style will help you avoid antagonizing your neighbors and will make the property more attractive for resale.

Choosing a house with some land around it goes a long way toward making the house look like it belongs where it sits. Even communities seeking to limit or ban the construction of big homes find it less objectionable when a builder puts a large home on an equally large plot of land.

Garage Placement

Just as the size of the lot plays into the aesthetics of the purchase, so does the garage placement. Side-entry garages minimize the impact of having three or four garage bays side by side, toning down the “garage mahal” look.

If side entry is not an option, consider a recessed garage design. Having a huge garage that sticks out in front of the house is not as attractive as a more understated look—for your neighbors or future buyers.

Energy Efficiency and Quality Materials

If you are building a new home, you should consider energy-efficient building practices and designs for new construction. The right heating and cooling systems, lighting, windows, and insulation can make a big difference in the long-term cost of owning the home.

You’ll also want to pay attention to the quality of the materials used to build the house. Many big homes use top-quality material on the front and lower-quality material elsewhere to save a few dollars. A beautiful brick or stucco facade faces the street, but vinyl siding is used for the sides and back.

It’s worthwhile to spend the extra money on high-quality materials.

McMansions vs. McModerns

The outdated and ostentatious McMansion is now being replaced, sometimes literally, by a McModern house.

Unlike McMansions, McModern homes are designed to reflect and riff on mid-century modern aesthetics. They sometimes, but not often, use sustainable materials.

McModern homes have a large footprint and have often been built on lots where a McMansion has been torn down. McModerns are designed to appeal to tech-conscious, educated, younger buyers with money to spend on amenities and square footage.

How to Avoid a McMansion

If you plan to build a large, newly constructed home, there are ways to avoid ending up with a McMansion. Working with an architect who understands the scale of homes in your neighborhood can get you a design that fits its setting. Using sustainable and high-quality building materials will remove the McMansion stigma.

If you have limited property, make sure your home doesn’t build right out to the property line, as many McMansions do. Just because a lot will allow for 5,000 or more square feet of a house doesn’t mean you need to use it.

The Bottom Line

The big house trend remains popular in the United States, and while some buyers have embraced smaller homes or even tiny homes, McMansions and large newly-built homes are in demand.

The coronavirus pandemic sparked a new interest in larger homes with offices, more bedrooms, play spaces, and outdoor amenities.

New construction trends show that while McMansions may not be popular, well-designed new homes with large footprints are in demand. Today’s buyers are looking for larger homes that don’t merit the McMansion moniker.
