Opening Up an Older Home: What Charleston Homeowners Need to Know Before Removing a Wall
The walls that once defined American homes are quickly disappearing.
Throughout the 1950s, ’60s, and ‘70s, compartmentalized floor plans were the standard. Separate kitchens, formal dining rooms, and isolated living spaces reflected how families lived decades ago. Today’s homeowners, however, are looking for something entirely different: bright, connected spaces where cooking, entertaining, and everyday life happen together.
For Jodi Crosby, founder and principal designer of Crosby Creations Custom Home Designs, helping homeowners transform outdated layouts into functional open-concept homes has become one of the firm’s specialties.
After designing more than 1,600 homes and renovations across the Charleston area over the past 17 years, she’s learned that opening a floor plan involves far more than simply knocking down walls.
Every Wall Tells a Story
The first question homeowners ask is often the simplest:
“Can this wall come down?”
The answer requires careful investigation.
Before any design begins, Crosby and her team trace the home’s structural load path by examining the attic, crawl space, roof framing, and foundation to understand exactly how weight travels through the house. While Crosby Creations identifies potential structural limitations early, a structural engineer is brought into every project to confirm which walls can safely be removed and what reinforcement may be required.
“We want homeowners to understand what’s possible before they invest significant money into a renovation,” Crosby explains.
That early collaboration helps establish realistic expectations while avoiding costly surprises later in the design process.
Why So Many Older Homes Feel the Same
One reason these renovations have become so common is that many mid-century neighborhoods were built from only a handful of floor plans.
According to Jodi Crosby, homes built throughout the 1950s and ’60s often share nearly identical layouts.
“If I looked back through all of our projects over the last 17 years,” she says, “there are probably fewer than a dozen different floor plans.”
Because of that consistency, many homeowners have similar goals: combine the kitchen, dining room, and family room into one cohesive gathering space while improving natural light and sightlines throughout the home.
Older Doesn’t Mean Poorly Built
Despite their age, many of Charleston’s mid-century homes remain exceptionally solid.
“The homes from the ’50s and ’60s are extremely well built,” Crosby says.
Their structural framing generally adapts well to renovation, even when walls are removed and new support beams or posts are added.
The most common issue isn’t the framing itself but the foundation. If foundation concerns arise, Crosby coordinates with structural engineers who provide guidance before foundation specialists complete repairs or reinforcement.
Before You Remodel, Do Your Homework
Perhaps the biggest misconception Crosby encounters is that homeowners can purchase a house and renovate however they choose.
In reality, Charleston-area renovations are shaped by municipal regulations, flood zones, permitting requirements, and insurance considerations long before construction begins.
One of the first conversations Crosby has with prospective clients focuses on gathering critical information, including:
- A current land survey
- Flood zone designation
- Property appraisal separating land value from dwelling value
- Local permitting history
- Municipal renovation regulations
Understanding these details early can determine whether a project is feasible before major investments are made.
Understanding the 50 Percent Rule
For many Lowcountry homeowners, one of the most significant renovation restrictions is the “50 Percent Rule.”
Many municipalities limit how much work can be completed on a home based on the dwelling’s appraised value over a designated period of time. Those timelines vary dramatically between jurisdictions.
Charleston County, for example, considers permits pulled within a five-year window, while other municipalities may evaluate much longer periods.
Because these regulations differ from one community to another, Crosby encourages homeowners to consult professionals before purchasing a property with major renovation plans.
“It’s heartbreaking when someone buys a house with big dreams only to find out they can’t legally do what they envisioned.”
Open Doesn’t Have to Mean Undefined
Removing walls doesn’t mean sacrificing organization.
Instead of relying on partitions, Crosby often defines spaces through architectural details overhead.
Exposed beams, coffered ceilings, and thoughtfully placed lighting help distinguish living, dining, and kitchen areas while maintaining an open flow.
Because today’s renovations typically feature continuous hardwood flooring throughout the main living areas, ceiling treatments often become the strongest visual tool for creating distinct yet connected spaces.
Local Knowledge Makes the Difference
Stock house plans can be an excellent starting point, but they rarely account for Charleston’s unique building requirements.
Height restrictions, flood regulations, neighborhood guidelines, and municipal codes frequently require modifications before plans can receive approval.
That’s why Crosby believes local expertise saves homeowners both time and money.
“There are things you simply don’t know until you’ve worked with these municipalities every day.”
Rather than relying solely on online research, she encourages homeowners to speak directly with professionals and municipal officials who understand the permitting process.
Research First. Renovate Second.
After nearly two decades in business, Crosby’s advice remains surprisingly simple.
Research everything.
“The best thing you can do for your peace of mind and your pocketbook is to become educated,” she says.
That education extends beyond Pinterest inspiration boards and online articles. Speaking with architects, structural engineers, local officials, and experienced designers early in the process helps homeowners make informed decisions and avoid expensive mistakes.
When the proper planning happens first, opening an older home becomes more than a cosmetic renovation. It becomes an opportunity to preserve the character of a well-built house while adapting it for the way families live today
