Load-Bearing Wall Considerations
One of the most common structural challenges in kitchen additions involves load-bearing walls. Generally, load-bearing walls are those that support the structure of your house, transferring the weight from the roof and upper floors down to the foundation. Kitchen walls, especially those dividing the kitchen from other main living spaces, but also always the exterior wall, are most of the time load-bearing walls.
If your kitchen addition requires removing a load-bearing wall to create an open concept design, If you plan on removing any load-bearing walls you are going to need a set of engineering plans. A structural engineer, or general contractor who has an engineer on staff can help you with this requirement. The cost for this type of structural modification can be substantial, with In most cases removing a load bearing wall and installing a beam will cost between $10,000 to $20,000 depending on the the length of the wall. Engineering plans may cost between, $5,000 and $8,000 depending on the size of the building.
