Project description

Our goal is to transform the block into an innovative complex that will meet the needs of Parliament and the public.

The redesigned block will provide office space for the Senate and the House of Commons and space for the Library of Parliament. It will also include renovated retail space.

About the design competition


We are finalizing negotiations for the design contract. In addition, we are finding out details about Parliament’s functional requirements. We will use these details to create a baseline project budget.

The construction estimate provided to bidders in the Request for Proposals is only a portion of a project cost estimate. The complete project cost estimate will be formed by a construction estimate based on a detailed scope, including final parliamentary requirements, and other significant cost items, such as:

  • the design contract
  • all other professional fees
  • design and construction contingencies
  • information technology
  • escalation and risk

Benefit to Canadians

The overall project is estimated to help create or sustain thousands of jobs in architectural design, engineering and construction.

Project background

The design selected for Block 2 was chosen through an architectural design competition.
