There are many reasons for renovating older buildings. For me, seeing buildings as a major contributor to the character of a place is a reason to renovate rather than replace. They represent the history of a community; why and how a community evolved, what the economic drivers were, what the people in the community valued. I also hate throwing things out, especially things that are rich with historical stories.
Renovating buildings is both gratifying and challenging. Reusing a building is usually more sustainable than tearing it down and building its replacement. Most historic buildings, which are the most challenging to renovate, are found in town centers where commercial activity was located and limited means of transportation kept housing close by. Breathing new life into historic buildings represents an opportunity for the community to reinvent itself without losing its identity. Honoring history will do that. That is where the gratification comes from.
The challenge is in renovating without ruining the building. They really don’t “build them like they used to.” 150-year-old masonry buildings were built to last. To continue that legacy, we need to understand historic construction methods and materials. Our contemporary impulse, of course, is to insulate. But an old masonry wall that has been kept warm and dry by heat moving from the interior to the exterior won’t respond well. Insulation introduces a freeze-thaw cycle that causes spalling brick. Wood beams from old-growth forests too, may have very different qualities from today’s wood. So, the challenge is in taking the time and putting in the effort to understand the building and its materials.
In a way, the science of understanding an old building is like designing in an established community. The challenge is to understand its history and evolution.
