When doing a big renovation (especially on an older home), there will most likely need to be new foundation work done. This was the case with the Encino Home.
Our design converted the garage into more living space, so we had to raise the floor to match the rest of the living area. This called for new foundations.
The rebar shown below went into the holes we cut in the garage floor. A column was placed on top of the rebar in the center of the cut. Then, concrete was poured in place. The new raised floor rests on these columns.
Also, during the demo work, we found that the house was missing foundations underneath many of the existing columns – meaning that they weren’t really supporting the house! (You can see in the picture that there is no concrete foundation beneath the column…)
Actually, the west side of the house was sinking! To fix this, we added concrete foundations underneath these columns.
Since we converted the garage into living space, we put in a carport per city ordinance – which also needed a foundation. The circled blocks are pieces of concrete (called “dobie”) that will go in first, then rebar lays on top of them. Next, concrete is poured in place to create a grade beam to support the structure.
