Besides checking the tablespace storage allocation method and parameters rebuilding a table can increase the size of the table due to the re-establishing of the pctfree factor. If row updates consumed most of the space reserved for updates then when these rows are copied to a new block that block is going to have pctfree reserved. The result could be that the total number of blocks necessary to hold the data increases. You are most likely to see this when the pctfree is set higher than the default.
