The Design Concept

Cross Section of the Senedd

The Architect’s vision behind the design was to create a building that rises out of the Bay engaging passers-by with an over-sailing roof that creates a place for people to gather and meet

The design of Senedd originates from sculpting the ground plane; the bay, to form the working spaces and sculpting the roof plane; the sky, to create the public space. The material enclosure between the two is as transparent as possible.

At the heart of the design is the wish to produce a building that symbolises an open democracy.  It has also been designed to make a significant contribution to sustainable development.

As part of the original design brief, the architect aimed to:

  • Generate a sense of open government and public accessibility
  • Provide a Quality Working Environment, a ‘fit for purpose’ building without being lavish.
  • Provide good access for people with disabilities
  • Respond Effectively to Change Over Time
  • Exploit Information Technology
  • Represent Value for Money, not just in the initial capital spend but in the ongoing “whole life” costs
  • Be a Good Neighbour by benefiting the local community and respecting and enhancing the existing environment in accordance with the Environmental Protection Act.

The following principles were adopted when designing the building:

  • The design makes good use of the physical advantages of the waterside frontage.
  • The nature of the exceptional site drives the building form.
  • The juxtaposition of neighbouring buildings with great views across the Bay contrasts containment and openness. These forces are typical of the greatest urban spaces.
  • The juxtaposition of roof and plinth orients the building outwards to the Bay, symbolising its role, as a national building that will give identity to Wales.
