See the entry in the Dolls House’s I have visited pages. As explained we visited the Tower, having failed to do so in the 11 years we lived in Chorley. In the process of booking I discovered they did touts of their Doll’s Houses and so we went again for such a tour.
Pictures inside were not allowed. The Tower was well worth visiting and they seem to do a variety of special events.

The picture above is from their website.
