| "It's also why houses typically don't have attics anymore." As someone who framed houses as a job and designed and built three of my own I disagree with your take on attics. It is common for houses not to have an attic because builders must build cheap to compete. Attic space can be cheap square footage, but it has to be part of the plan from the beginning and is difficult to make it an option to pick. You can indeed have an attic with "attic trusses". They are still built out of dimensional lumber and stamped connectors - the bottom chord will be much larger. I've seen them span 36', not sure what the limit is. On one house, to do a partial attic was only $2000 extra for the trusses. Attics present other problems/expenses too, like additional stairs. (Many plans didn't have a place where extra stairs can be added as an option AND work with the truss layout. HVAC is another issue. You either end up with a second system for the attic or need to have space in the floor below to run ducts to the attic space. Again, most of your cookie cutter plans didn't leave a space for this. When walking my HVAC guy through my house to plan ducts he asked how much of this closet he could have for ducts. I told him "as much as you need to make it work correctly". From the look on his face you'd think he won the lottery. He replied "no one ever says that!". Attic spaces require different insulation techniques, they aren't difficult, but cookie cutters don't like different. I've used attic trusses on 2 of 3 houses. The one where I didn't was because stairs, HVAC and I didn't need more space (full extra height basement, daylight windows - that was enough). |
