Description

Stage 1

A DIALOGUE WITH NATURE
The natural landscape of Ottawa is defined by the Ottawa River and the hills and foliage that flank it, whereas the iconic, imposing built form of the Parliament Buildings stand separate from that landscape, formally exerting their own identity in contrast to the surroundings. Beyond Block 2, the pedestrian activity of Sparks Street and the urban fabric provide yet another significant point of context for the buildings of Block 2 to react. As such, our proposal for the Parliamentary Precinct Redevelopment Block 2 is not meant to be monumental, but modest in its venture to unite the opposing forces of these natural and urban landscapes. A building for transparent decision-making should be equally democratic in its organization. It offers diverse, egalitarian spaces - formal and informal, built and natural, large and small - for congregation, representation and discourse.

CONCEPT DIAGRAM I INTERWOVEN GARDENS
The historic fabric will be conserved in accordance with internationally accepted conservation techniques, retaining as much historic material as possible. Opportunities to repair rather than replace building elements will be explored. Where possible and appropriate, missing elements will be reproduced. All work will be in compliance with the Standards and Guidelines for the Conservation of Historic Places in Canada.

The intervention has a stately presence on Wellington to fulfill its role as the fourth wall of the Parliamentary forecourt. Materiality and quality are comparable to the flanking OPMPC, Sir John A. MacDonald, and Wellington Buildings. In contrast, the street level character of Sparks Street is defined by a lively mix of prestige storefronts, typically featuring extensive glazing and refined detail in keeping with the historic role of Sparks Street as Ottawa's most prestigious high street.

Based on the varying structural existing conditions, lack of a robust seismic resisting system, and inconsistent floor levels, the design has been developed based on the demolition of the existing structures, except the Victoria and Valour buildings, while retaining the existing facades. Modifications to the Victoria building will include a new concrete core, which will address seismic capacity requirements.

Stage 2

DESIGN APPROACH
Block 2, with its existing buildings of diverse quality, borders two important public streetscapes: The Parliament Buildings and the Lawn to the north along Wellington Street, and the lively and more urban Sparks Street to the south.

The future parliamentary administration buildings together with the future Indigenous Peoples' Space, not only form a new political and democratic entity for all Canadians; they also offer an important urban element for the citizens of Ottawa.

At the streetscape, our approach proposes a largely transparent and human-scaled horizontal datum, which preserves the facades of the Marshall and Canada Four Corners buildings while complementing these with new transparent facades designed to foster a sense of openness and activity. These new facades contrast the more somber faces of the remaining buildings on Block 2, preserving and respecting the grain of the urban environment. Above this street- level datum is the statelier facade of the building proper, modestly glazed to ensure optimal daylighting conditions for office and meeting spaces, horizontally articulated and characterized by sun-shading elements of varying depths corresponding to the structure's orientation and sun angle.

CONSERVATION APPROACH
Block 2 consists of a heterogeneous mixture of buildings of varying heritage value. The approach taken to the block as a whole is Rehabilitation; that is, in accordance with Standard 11 of the Standards and Guidelines for the Conservation of Historic Places in Canada, the heritage value and character-defining elements will be conserved, and the new work physically and visually compatible with, subordinate to, and distinguishable from the historic place.

The fundamental functional requirement of the proposed program is that the formerly autonomous individual buildings be integrated into a new whole, an obviously significant and irreversible intervention. To preserve the genius loci of the site, which is defined by the complex assemblage of buildings with diverse expressions, the new structure is equally complex in its character, woven into the existing buildings to avoid the presentation of an overbearing, monolithic structure.
