Kitchen Addition

My wife and I are in the middle of a kitchen remodel and I have a couple of questions about lam beam installation/options.

We are installing two new beams to open our kitchen up. Approx will be 24x24 which will have a small hearth room area in this new arera.

One beam will hold the ceiling joists of the kitchen and one beam will hold the roof rafters.

The ceiling joist beam is no big deal however the roof beam is where we a running into questions. The new beam 5 1/4x 13 7/8 if installed under the top plates will push it below the ceiling line and be visible from below.

What options do I have to install this differently to keep it up in the attic above?

My suggestion would be to explore the options of a different beam. Sometimes you can simply go with additional thickness and less depth, although it depends greatly upon the span and the imposed loads. Another option that is commonly used is to add 1/2" steel flitch plates bolted in the middle of the plies of LVL or on either side. Yet another option is a steel beam instead of an engineered wood beam.

Unfortunately, we can't size the beams for you, as it requires a thorough analysis of the structure and the imposed loads. My suggestion is to hire a structural engineer to come out and determine what will work best for you. Engineers usually charge between $300 and $500 for a one-time consultation and stamped prescriptive letter. You can call your local Homebuilders Association (HBA) and they often have engineers that are members that they can recommend.
