That's quite right. We did not want to have the roof over-exposed. We wanted to make sure the design was compatible, subordinate, and distinguishable. In fact, the National Capital Commission has three sight cones that mandate the height of new construction in the area of the Parliament Buildings, and we needed to respect those sight cones, so this did restrict the elevation of that roof.
We work with the FHBRO, the Federal Heritage Buildings Review Office, and the National Capital Commission. We have conducted a number of design review committees. We work with the parliamentary partners as well in completing these designs and moving forward with them. The roof has been modelled by experts in Guelph, Ontario. There was a question asked earlier about snow. A scale model of this structure has been modelled in Guelph, Ontario, for snow loading, wind loading, and so on. Very detailed engineering has been done on the structure, and the glass roof has been designed to easily handle snow loads. It has been designed so that it is easily maintained as well.
About the height of the roof, you're quite right. We are restricted, and rightfully so, I believe, because we want to be compatible, subordinate, and distinguishable. These are basic design elements that we want to respect when we're adding a construction to a very important heritage building such as this.
