Evergreen on Blackburn

In partnership with Windmill Development, the Evergreen on Blackburn development project is a large-scale example of Cross Laminated Timber (CLT) construction and adaptive reuse: converting an existing church into a living and recreational space for the community. We are thrilled to help set a precedent for future sustainable endeavours in Ottawa.

With the preservation of the Church's heritage in mind, existing design elements are carefully woven into the new surrounding building, breathing life into the church and seamlessly blending the two buildings.

Paying Homage

Paying Homage

By integrating the stained-glass patterns found throughout the church into the design of the metalwork, a coherent transition is achieved between the old and new structures.

Design Insight - Embracing Heritage

The new construction serves to complement and provide a backdrop for the 123-year-old church.

The repetition of buttress-like elements, along with the intent to utilize reclaimed stone from the demolished Bate Hall provides both a material and architectural connection between both buildings.

The incorporation of eco-conscious elements throughout the project is our priority: it is expected to be carbon-neutral, promote local food and agriculture, and encourage further community engagement.

Sustainable development - CLT

The development will be the first multi-level Cross Laminated Timber (CLT) building in Ottawa - emphasizing our commitment to sustainable building practices. CLT is a sustainable alternative to form walls, roofs, floors and even ceilings, reducing the global warming potential of a building by retaining carbon dioxide from the atmosphere.

The amenity terrace offers a space for bike storage and other recreational use.
Careful attention to lighting, accessibility, and landscaping provides a welcoming space for residents and visitors, encourages community engagement and social interactions.
Window Typology

Window Typology

The windows of the proposed building serve as a continuation of the same architectural language of the Church. By using brick, a material more aligned with the local residential palette, the new development seeks to remain subservient to the church, visually pushing it to the forefront.
