Framers construct the second story floor system to match the layout of the main floor system. A second story house offers additional living space without the need for a larger foundation, leaving you with more room for recreation or gardening in your yard.

Framing the second floor is not a whole lot different from framing the first. Whereas on the first floor, the sill plate was pressure treated lumber, this isn’t necessary on the second. Also, the bottom plate was bolted to the concrete foundation on the first floor, but on the second we simply nail it to the rim joists as you can see below.

Framing for a second floor is a crucial aspect of construction that ensures the stability and safety of your home. Whether you're a DIY enthusiast or a professional contractor, understanding the fundamentals of framing can greatly enhance your building skills.

The second floor is constructed by a series of “joists” or long I-beams made from Engineered wood and OSB, connected to the outside walls and load bearing members that carry the weight of the house.
