Timber Floor and Roof Framing

Lets backtrack for a second. Once the foundation was repaired and the bond beam was poured, we prepared the timber framing for the roof and floor. The timber was ordered from a local Amish mill which was sustainably harvested.

The girder is used to denote the main horizontal support of the structure, which supports smaller beams aka joists. The floor joists were cut to length and then the edges were cut to fit the bond beam. The girder was also cut to length and notched to fit the joists.

This was my first experience in the world of timber framing. Miles and I worked on the simple joist joints, while John (an experienced carpenter) worked on the harder joints, like the “gooseneck” on the girder.  This joint linked the two girder beams together because the wood was not milled as long as the length.

The hole was dug in the floor of the basement before the cement was poured to support the load of two larger vertical beams.

The difference is that the rafters overhang on the outside by about 3 ft, so they are notched to rest on the wooden beam and then secured with long screws.
