According to Realtor, Holmes isn’t a fan of sunken living rooms and believes they only decrease a home’s value. “If you don’t pay attention, you’re going to fall down and bust an ankle,” Holmes pointed out. “Because that wood floor is the same color on the step as it is on the floor below.” Although this was a popular trend through the 1950s and 1960s, a step that is typically 6 to 8 inches deep can be dangerous for the elderly and small children, per RosieOnTheHouse.
In the end, this sunken living room — pictured above and featured in Season 1, Episode 6 of “Renovation Impossible” — was transformed into a leveled dining room (via Amazon Prime). Holmes and his crew raised the floor by first pouring on a layer of cement. Then, they laid down several wooden boards on their sides to make the flooring level with the rest of the home. “This way, when we put down the new flooring, it’ll all be even,” Holmes explained. After raising the flooring and removing the wall separating the room from other areas, the residence instantly felt more open and brighter.
