Subdivision will always work on the entire object. If you have areas that are smoothing and you don't want them to, you need to add detail e.g. introduce more surfaces at corners or edges you want to appear sharp.

Try subdividing a block e.g. 5x5x5, compared with a cube. If you reduce the size of the square surfaces near an edge of a block, you can make the edges look a lot sharper.

You can also extrude-in-place by selecting some surfaces, pressing extrude and clicking on the selection. This will insert extra surfaces at the edge of the selection. You see that the new surfaces can be hard to see if you switch off display of subdivisions (press 'd' to switch display of subdivisions).
