  1. I'm looking to build a 24×30 garage with a second story on it. The upper level will be one large space with no interior walls. I'm trying to determine how I should frame this 2nd story?

  2. Hey ! How do you know if the structure is solid enough?

  3. On the first example, it is a good way to support a wall, but is important to specify it all depends on the size and span of the floor joists under the wall, as well as the weight above the wall. All these factors are of the essence in avoiding a floor sag and eventually collapse.

  4. Thank you.

  5. Thanks for the info. In the second example, can I remove the first floor wall in the middle without adding any post? Do I need to add more joists or strengthen the outside walls to achieve that? Thanks.

  6. In the first example where the 2nd story wall is load bearing and is perpendicular to the floor joists, do you need to increase the size of the floor joists for the load somehow? Ex: The area is a sleeping area so you use the 30/10 span tables. Which span tables would you then use if you added the 2nd story wall? Thank you

  7. If the upper wall is not load bearing, can we skip the double joists and double studs? We're looking to split a large room on our second floor, the only 'load' would drywall and some attic insulation.

  8. How much support would I have to add in basement to install an island in the kitchen that will be four 18-24" cabinets topped with 13 square feet of granite?

  9. great visuals and explanation on load bearing wall.

  10. brick homes built in the late 1940's, do they have solid foundations so to add a second floor?

  11. Thank you for sharing

  12. Thanks for share your knowledge.

  13. Exactly what I had in mind thanks
