Why we use it
BCG uses copper where durability, craft, and aging are part of the architectural intent.
Character
Bright at installation, copper moves through browns and eventually toward green depending on exposure.
What we look for
Appropriate gauge, soldered or formed details, compatible fasteners, and correct separation from dissimilar metals.
Design considerations
Copper should be placed where patina makes sense and runoff will not stain sensitive surfaces below.
Installation considerations
Expansion, galvanic reaction, slope, soldering, and clean terminations are central technical decisions.
Common mistakes
Mixing incompatible metals, ignoring runoff staining, or using thin material where formed work needs substance.
Maintenance + aging
Copper generally ages with little intervention. Cleaning should be deliberate because patina is part of its value.
