The New Brunswick Legislative Building is the current building that houses the Assembly. It opened in 1882, having been constructed by J.C. Dumaresq, following the destruction of the original building, known as Province Hall, by fire in 1880. It is a Victorian building with a 41 metre wide dome.
The legislative chamber is designed to have four rows on the government side and three rows on the opposition side. This is because elections have traditionally yielded a strong government majority; in fact on occasion, such as currently, even with many of the seats on one side of the House, the government has spilled over to the opposition side. Quite often the House is oriented to have only two rows on the opposition benches, in the event of a large opposition adding a third row makes the opposition benches rather crowded.
