I assume you are referring to the changes in the home of Silas Marner after he has taken in Eppie and in Book II of this great novel. We can find the answer to this question in Chapter 16, which transpires sixteen years after the decision of Silas to take in Eppie and look after her as his own. Clearly a number of things have changed, and growing up with Eppie, who is now a young woman, has created massive transformations both in Silas himself and in his abode. Note how the text describes his house now:
The presence of this happy animal life was not the only change which had come over this interior of the stone cottage. There was no bed now in the living-room, and the small space was well filled with decent furniture, all bright and clean enough to satisfy Dolly Winthrop's eye. The oaken table and three-cornered oaken chair were hardly what was likely to be seen in so poor a cottage: they had come, with the beds and other things, from the Red House, for Mr. Godfrey Cass, as everyone said, did very kindly by the weaver...
Thus clearly the interior of the cottage has changed thanks to the generosity of Godfrey, giving Eppie and Silas some lovely, "decent" furniture that they are able to use and enjoy in their lives.
