Block 2 design and construction

Block 2 is the city block directly facing Parliament Hill in downtown Ottawa. It is bounded by Metcalfe, Wellington, O’Connor and Sparks streets.

The Block 2 architectural design competition was launched in spring 2021. In May 2022, Zeidler Architecture Inc. (Toronto, Canada), in association with David Chipperfield Architects (London, United Kingdom), was selected as the winning team in the design competition.

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


Public Services and Procurement Canada, supported by Zeidler/Chipperfield, is working with Parliament to finalize the functional requirements in order to create a baseline project budget and schedule.

The total project cost estimate will be based on a construction estimate that will include the detailed scope of the project 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.
