The Award of Merit in Conservation – Small & Lovely was given to Chris Huntley of Heritage Restoration Inc.; and Edwin Rowse, and Sydney Martin of ERA Architects Inc. for the Parkwood National Historic Site – Greenhouse Conservation. The project was applauded by the judges for demonstrating exemplary analysis of existing structure, guided by the Standards and Guidelines, and a strong attention to understanding phase and accuracy of execution of repairs and replacements. The judges were also impressed with how the building remained operational within the duration of the conservation work.


Built in 1915 with the estate house for Colonel Sam McLaughlan the existing Greenhouse at Parkwood National Historic Site had undergone alterations in the 1970s or 1980s that modified their original design and material composition. After 30-40 years, the structures, though still functioning, were in very poor condition and repair to ensure the long term stability of the heritage fabric was a priority.

The Greenhouse Conservation project was the final phase of a long term project that included a Greenhouse Conservation Study Report and the conservation of the Vinery as a pilot project. The current phase included the conservation of the five remaining greenhouses in the complex. Archival records, images and remaining original fabric were used to inform the restoration of the five greenhouses. The conservation scope included the repair of original fabric, selective replacement of components beyond repair, and replacement of the incompatible lexan cladding with new glazing to match the original design.
