2 of the most impractical home design choices, according to the Property Brothers

• Insider spoke to "Celebrity IOU" stars Drew and Jonathan Scott about home design.
• The Scotts shared what they think are the most impractical designs.

It's no secret that Drew and Jonathan Scott are interior design experts thanks to their tenure as HGTV stars on shows like "Celebrity IOU" and "Property Brothers: Forever Home."

Insider spoke to the Scotts about "Celebrity IOU," which features stars renovating homes alongside the brothers for loved ones in their lives.

The show returned on Monday, guest-starring Heidi Klum.

As "Celebrity IOU" highlights, one of the Scotts' skills is creating homes that are as functional as they are beautiful, unlike many designers who prioritize aesthetics over use.

Given their expertise, Insider asked Drew and Jonathan about the most impractical design choices they see in homes.

"I hate when people have too many levels that just create trip hazards," Jonathan said. "I am a clumsy person, so I am the person who will fall down the stairs."

"You see a lot of the trends from the '70s of sunken living rooms or even something like a two-tiered island and whatnot," he went on to say. "I don't love doing them because I like keeping things simple."

Drew, on the other hand, thinks people run into impracticality when they make bold design choices.

"Some people go bold with certain designs," he said. "Nowadays, there are some very vibrant aesthetics out there, and people really want to express personality."

"You feel this is your forever home. But a lot of times people say that, but then maybe they have to move for their job or something. Or maybe they have more kids, they need a bigger house, and they're forced to move," he said.

"All of a sudden, you've spent thousands of dollars on something like a tiger or a leopard-print countertop stone," Drew added. "Something that's so bold is gonna be very expensive to change out."

"If you go bold and show your personality, do it in areas that are easy to swap out, like throws or accent chairs or artwork instead of something that's a big ticket item, like the color of your cabinets or your countertops," he suggested.

In addition to "Celebrity IOU," the Scotts are also still filming episodes of "Property Brothers: Forever Home."

"We're casting in LA right now for 'Property Brothers: Forever Home,'" Jonathan told Insider. "If there's anybody out there who has a home, whether you've had it for six days or 60 years, but you want to make it actually functional and beautiful and make it your forever home, tell him to come over to propertybrothers.com and check out applying for it."

"Celebrity IOU" airs on HGTV and Discovery+ on Mondays at 8 p.m. ET.
