What’s Wemmick’s home like? What does it say about him?

Wemmick isn't a man of extravagance but of simple comfort. He appreciates guns!

"Wemmick's house was a little wooden cottage in the midst of plots of garden, and the top of it was cut out and painted like battery mounted with guns."

"My own doing," said Wemmick. “Looks pretty; don't it?"
