Why we use it
BCG considers exterior materials together so architecture, water management, maintenance, and neighborhood context stay aligned.
Character
The strongest exteriors rely on proportion and material honesty rather than a crowded palette.
What we look for
Durability, compatibility, exposure, lead times, maintenance expectations, and how each material transitions to the next.
Design considerations
A limited exterior palette usually ages better. Color, texture, shadow, and scale should be studied in natural light.
Installation considerations
Drainage planes, flashing, clearances, ventilation, and fasteners must match the chosen materials.
Common mistakes
Combining too many materials, ignoring clearances, or treating exterior selections separately from the envelope.
Maintenance + aging
Exterior materials should be inspected seasonally and maintained according to exposure and assembly.
