By 'expansion' of House Redoran I gather you are referring to the player's stronghold at Bal Isra since the approximately sixty quests added by LGNPC Pax Redoran, Vivec Redoran and Indarys Manor are not insignificant.
Google located a few:

This appears a modest expansion of Bal Isra, but it seems that little or nothing has been done to the player's residence of Indarys Manor.

This adds to Redoran holdings throughout Vvardenfell including a substantial expansion of Bal Isra. Since I have not examined the mod myself I cannot say what changes are made to the interior of Indarys Manor, but I suspect they are minor.

This link to a work in progress thread has not been active since the fall. It aspires to be a mod in the style of Rise of House Telvanni and Grandmaster of Hlaalu with both a stronghold expansion as well as additional (Archmaster) quests. They had a forum, but I cannot find it any more. The only other reference is this http://www.youtube.com/watch?v=hw8qF9N_kcY showing the changes to Bal Isra and the interiors. It is a little too over the top for my taste, but I recall Helena having some promising ideas for quests. The lack of progress may indicate the project has folded. However the principle modder seemed young (a student) so perhaps work will be rekindled this summer.
Although you have not expressed an interest in such a mod, http://home.earthlink.net/~cyran0/TheRedoran.htm was designed to slow the player's rise in that Great House when the player uses a mod like Pax Redoran that adds so many new quests.
