The two houses together form a perfect bicameral system, meaning they perform identical functions, but do so separately.

The seat of the Chamber of Deputies is the Palazzo Montecitorio, where it has met since 1871, shortly after the capital of the Kingdom of Italy was moved to Rome at the successful conclusion of the Italian unification Risorgimento movement.

The term of office of the House (as well as the Senate) is five years, but can be extended in two cases: The electoral system is a mixed-member majoritarian with 37% of seats allocated using first-past-the-post voting (FPTP) and 63% using proportional representation, allocated with the largest remainder method, with one round of voting.

In order to be calculated in single-member constituency results, parties need to obtain at least 1% of the national vote.

During this time the prerogatives of speaker are assumed by the vice president of Chamber of Deputies[2] of the previous legislature who was elected first.
