Quote from: John Raabe on January 21, 2011, 04:16:00 PMI think what OJ is suggesting is to put this new beam under the house side of the deck thus taking the load off the house foundation and sidewall. This is a good idea and will also allow for good flashing to keep water from the deck side getting into the house wall and floor. When the deck needs to be rebuilt (and it will age faster than other parts of the project) this will be a stand alone project.

In the first photo you posted it looks like that is what you have built.In the first page of this thread I think we decided you should not be adding new weight to this foundation and that the deck should be free standing and not adding to the wall load with hangers. If I understand what you are suggesting, you plan to use much the same foundation plan for your deck as you used for the house? Decks should be designed to carry even more load than house floors (typically 60 psf rather than 40) because they can have very heavy loads during a party or such. Not that there aren't thousands of existing decks that are built less strong than house floors - there are. Usually this will not be a problem if lightly used. But a failure, especially when the deck is high in the air and loaded with a bouncing crowd at a party, can be devastating.

The existing beams will now support most of the main level floor loads. This would be a good way to carry the taller 6" walls and the extra weight of a loft.
