Knox Presbyterian Church engaged OakWood Builders and IDEA in a Design-Build arrangement to facilitate the construction of an addition to the West face of the building to incorporate much needed barrier-free access to the facility. The project also added congregation space, an education classroom and renovated a number of the existing aged portions of the building. This project involved a significant amount of research into the history of the Church and detailed planning with the City of Ottawa in ensuring that the character of the original building and subsequent addition were maintained.
