Today, I purchased some of the basement master bedroom framing materials which include two 2″x4″x12′ & four 2″x4″x8′ treated wood for the based framing on top of the concrete floor, six 2″x6″x8′ for three steel posts wrapped around and ten 2″x4″x8′ for general framing (picture 1). Why 12′? It should be as long/straight as possible to keep all framing on the same straight line. After all framing on top of it is nailed or screwed, then cut out the portions which are not required.
Of course, the first step is for fire safety and it is to seal off the existing small wood gaps on top of the wall insulation on two sides of its wall using the fire block sealant as shown in the second picture.
This project probably will take a while and it may stretch to years. Who know? But, it at least keep me busy to do something.
