A cousin of small bangla houses in Bengal, India—hence the name—both Craftsman- and Prairie-style bungalows caught on in middle America in the early 20th century. Their overhanging eaves provide shade and protect windows from inclement weather. Low ceilings inside trap heat during harsh winters, while exterior porches catch cool breezes in the summer. Dormers protruding from the roof create extra living space in what might otherwise be an unused attic. Bungalows are often built around a common courtyard, preserving green space. They are typically sided with native wood species and have either locally fired brick or fieldstone porch piers.
