The rafters are installed! The pitch is about 46 degrees, which adds plenty of space in the loft. We used more of our reclaimed cedar 2 x 4's for rafters. Below you will see that we have reinforced them with hurricane ties. Wind forces and road turbulence are always considerations when constructing a tiny home.
Hurricane ties here and at the ridge beam will keep our roof system unified with the rest of the house. These are Simpson brand, the most common choice for this application.
We framed the gable ends after we installed the rafters. Here you can see that there will be ample storage over the entry and front window seat. . . We have the home buttoned up due to inclement weather!
Walls keep flying up and framing continues. Both structural and envelope integrity are foremost in our minds at this point...
We opted for California corners in the framing, which increases envelope efficiency. By rotating the intersecting wall's corner stud 90 degrees the builder can insulate across the full stud bay, which helps in two ways:
As with the floor framing, we installed cross bracing in the wall framing. Noticeable differences in overall rigidity occurred after this step. You might be wondering about the insulation in the corner stud bays. We needed to complete this step at this point because the California corners make it difficult to wedge (rigid) insulation into them once the cross bracing is in place.
More reinforcements! We tied the wall framing to the entire floor system with 10" galvanized bolts and massive square washers (we found another use for the square washers...more on that later). The house is officially one with the frame of the trailer. Onward and upward!
We had the help of a friend next door to raise our first and heaviest wall. We installed sheathing prior to raising the wall, which makes glueing and screwing the ZIP board easier. The one draw back to this approach is that it adds weight to the wall, making it a little more difficult to raise.
A note about our sheathing: We prefer the AdvanTech ZIP System for a few reasons: time and money. Our price was $10/sheet (with a $3/sheet rebate available at the time). 7/16" OSB was $20-$30/sheet at local stores. We bought two rolls of tape at $30/roll (we will need some for the roof too...more on that later) which seals up the seems. There is no need for a house wrap, so a tremendous amount of time is saved here. This product is a no-brainer.
The second wall went up according to plan. At this point you can feel the inner dimensions of the home. Honestly it feels larger than it looks. It's easy to imagine the layout of the living room, kitchen, and bathroom. . . Thrilled about getting to the 2nd story!
In the interest of keeping our structure level and square we cut all of our studs with stops so corresponding components would be precisely the same lengths. So much of the time spent building a home is in the design and planning process. Once all the prep work is done, putting the parts together goes relatively quickly and is a real treat.
Here you can see the first wall assembled and ready to raise. We are including 4 x 6 cedar timbers in the design and they will be weight-bearing. This requires we build them into the framing. Notice the three windows also! There's going to be a lot of light in this Wishbone Tiny Home.
Here's a detail of the first purlin. This will extend out over the porch area and support a gabled entry.
