# Removing a supporting interior wall

In about a week I’ll be closing on a new house and am looking to remove this short distance of wall between the kitchen and living room. Based on the direction of the roofline, I’m pretty sure it’s a supporting wall, which means I’ll need to put in an LVL beam. A few questions I’m hoping someone here can help with:

1. Will I need to run it the entire length of the wall (e.g. dig into above the current doors)?
2. What type of wood should I purchase to support the LVL beam on either side?
3. Can you recommend a good online calculator to figure out the dimensions of the LVL beam I need to buy, or tell me the dimensions?

1. It’s a single floor space, so no extra weight above it other than rafters and roof
2. Snow: the house is near Cleveland Ohio, so in the winter we get (on average) up to a foot of snow at a time.

• Do you have a basement under the house? The space marked basement seems to be odd(maybe a typo?) If you do have a basement, is there any beams under that wall? Mar 15 at 19:22
• The section I'm removing the wall from is a ranch, the other 1/2 is a split level.

• "Based on the direction of the roofline" — which direction does the peak run? Mar 16 at 13:26
• It is opposite the direction of the wall which means joists are perpendicular to it

Will I need to run it the entire length of the wall (e.g. dig into above the current doors)?
Depends. What are the existing headers bearing on? What will you bear new trimmer studs for the new beam on? If you can run new trimmer studs down to the subfloor and block underneath to something capable of bearing the load, you can use a separate beam.

What type of wood should I purchase to support the LVL beam on either side?
Standard SPF studs are fine. There really is nothing else commonly available. The span may call for them to be doubled.

Can you recommend a good online calculator to figure out the dimensions of the LVL beam I need to buy, or tell me the dimensions?
Talk to your lumber yard. They have people on staff trained to do this. Even with a couple decades of homebuilding experience I don't trust a simple calculator to cover all the nuances of a situation.

Also note that this kind of thing typically requires that you pull a permit and facilitate inspections. Therefore, present your proposal to the inspection office before starting, to reveal any concerns they may have before you have to tear it apart and redo it.

Also also note that you need to properly support the framing above while you do this work. That's often done with a temporary wall on one or both sides, but it depends on the actual framing scenario. Be safe.

• Thanks. I was asking about type of wood for supporting the lvl beam because I didn't know if it required a special kind of support since it'd be holding more weight, or if normal framing lumber (e.g. 2x4's) was enough.

• In my case they used another form of manufactured lumber, specifically designed for lengthwise compression. I don't remember what it was called. They also had to install a steel C-beam in the basement to carry the newly concentrated force to main beam and foundation. This is why one hires an engineer to design it properly. Mar 15 at 21:32
