Bernie posted a comment query after seeing my latest pictures on the building materials being wood rather than concrete and wondered why. When I talked to the builders intially, they told me that building bylaws in Burlington allow the use of wood for buildings under 5 stories, so our building being only 4 stories lets the builder use wood rather than concrete.
In my opinion, I am guessing that it is far cheaper to build using wood frame than concrete hence their decision. Personally, I would prefer concrete as I find it is a better sound proofing that what will occur with a wood frame. That said, when I expressed this concern to the builder they indicated they would be ensuring sound quality. I guess we will see.
