Q. We bought our home three years ago, and are finally ready to finish our basement to make a family room, guest bedroom and a bathroom while enclosing our laundry. Right now it’s just a big open space with a lot of columns. The ceiling is low, and we’ve had estimates to cut down the basement floor. It seems like a lot of money to do all these things at once, but we understand that we need to do it before the prices for materials, as we’ve been warned, go a lot higher. We want to know what needs to be done if we want to lower the floor, take out two columns so our recreation room is bigger, and put in a bathroom. Is there any way to save money?
A. The first part of your question was answered two weeks ago, when I explained basement bathroom requirements and noted that many municipalities disallow basement bedrooms. This is because of the challenge of rescuing someone from a basement in a catastrophic event like a flood or fire.
Lowering a basement floor or removing columns can be extremely dangerous, and should be planned correctly before you proceed. Removing basement columns requires gathering information on what’s above them. The weight and movement of materials, when added together, isn’t to be taken lightly, so to speak. The loads are extreme when following the path of load distribution all the way from the roof through the structure. Temporary loads, referred to as “live” loads, are often left out by untrained planners. Snow, wind, people moving around, temporarily filled bathtubs, kitchen equipment and islands also contribute.
Charts and graphs in the building codes outline minimum requirements for some of these contributing factors, and we professionals have to always keep in mind that these are minimum requirements, often without conservative safety factors for unforeseen circumstances. Gathering the information to then start to calculate, using formulas, is a process.
In many cases, it’s best to draw a set of plans showing the different levels that can then be stacked one above the other, to find the common points where loads will transfer. Most of the time when I’m called to look at sagging floors, cracked walls and ceilings, I realize that the person who made their best guess didn’t follow the steps I described.
Lowering your basement floor is complicated and not cheap. Stay tuned for Part 3.
