About the Senedd

The Senedd, which was opened in 2006, is situated in a prime position on the waterfront in Cardiff Bay. It houses the National Assembly for Wales’ Siambr (debating chamber) and Committee Rooms.

The Senedd is completely transparent at the public level and sits on a slate plinth which steps upwards from the waterfront and houses the private spaces of the building. A lightweight, gently undulating roof shelters both internal and external spaces and is drawn down to form a funnel-like enclosure over the Siambr.
