Right, so the fireplace is an improvement, and getting the builder to replace the stumps and re do the floor, and take out the leaning chimney in my Ip is also an improvement, becuase I bought the place with sloapy floors and a leaning chimney, but, if I borrow the money to do the improvements, I can claim the depreciation on the improvements, and the interest on the loan to improve the property. Its not as good as it would be if it were classed as a repair, but its still pretty good, especially as I can charge more rent.
