TMZ says that HGTV IS planning on turning the "Brady Bunch" house into a COPY of the Bradys TV house . . . but it won't be easy. The indoor scenes were filmed on a set, and the inside of the real house looks nothing like it.
So they're going to basically gut the inside, and add onto it . . . going from 2,400-square feet to 4,000-square feet.
TMZ also claims HGTV DOES want to bring LANCE BASS onboard the show, either to help with the renovations or to host. Then after the show, HGTV will sell the house, but by that point it could go for $4 million to $6 million, which might be out of Lance's price range.
