That option illustrates the challenge, I think. It's not an option that we're saying or advocating should be implemented. We're working on a broad range of options. What that indicates is that if the House wants to maintain its existing set up, that's essentially how to make it work. There are a lot of downsides to that, and that's recognized.
Then it's a conversation about what other ways would work for the House of Commons, whether that would be—and I'm just kind of speaking out loud here—kind of progressing towards benches similar to the U.K. model over time; whether that is taking a very different, more radical approach to putting in the seating; or whether that is enlarging the chamber. These are very important considerations that would, as Ms. Garrett indicated, make it critically important to take decisions as early as we can and have those decisions last until the end of the project.
Enlarging the chamber is very challenging in its own right. There are some significant challenges from a structural and architectural perspective in that part of the building. It's possible, as most things are, but there would be significant costs involved. To make that decision, we would have to, I think, make sure that we've touched bottom on a broad range of options and really be sure that we settle with consensus on what we feel is the right option.
