For more than a decade, urban renewal has seen the renovation of former manufacturing facilities into trendy loft-style offices, condominiums, and apartments. Most of these buildings belong to the ‘brick and timber beam’ vernacular constructed in the first half of the 20th century. Many constraints govern the design of any building, but a renovation involves the most significant—the building already exists. These brick-and-beam buildings vary widely in terms of construction quality, materials, past performance, and ongoing durability.
