Spanish colonial houses are architectural structures that originated during the Spanish colonization of the Americas. These homes typically feature thick adobe walls, red-tiled roofs, and arched doorways. They often include a central courtyard, which serves as a gathering space and provides natural light and ventilation. The design of Spanish colonial houses reflects a blend of Spanish and indigenous influences, emphasizing functionality and comfort in warm climates. Common materials used in construction include stucco and wood, while decorative elements like wrought iron railings and colorful tiles add character to the homes.
