Lucas Lodge is the home of Sir William Lucas and his family, including Lady Lucas, Charlotte Lucas (until her marriage), Maria Lucas and the other Lucas children. The narrator tells us, while describing Sir William, that after his knighthood, he “removed with his family to a house about a mile from Meryton, denominated from that period Lucas Lodge, where he could think with pleasure of his own importance.”
Architecture and Decor
In a novel full of information about architecture, we are not told very much about Lucas Lodge, except that it is within proximity to Meryton and a short walk from Longbourn. We also know that Sir William hosts at least one big party there, suggesting that the Lucases have, at a minimum, a few nice public rooms which can accommodate the major families in the neighborhood (which we know is no more than "four-and-twenty families").
History and Context
We can, however, make some inferences about the house. Since Sir William is a merchant who made good, the house is certainly not ancestral and likely came without significant agricultural land attached to it. While it is clear that Lucas did not build the house, it may well be a newer home (or an old decrepit one). In either case, it’s unlikely that he’d have great reverence for the original design and, given the Lucases' pretensions in other areas, he has probably decorated the house in keeping with modern trends, rather than a more old-fashioned look.
