Steps (exterior)
Definition
Steps are the fundamental units of a staircase or exterior stairway, consisting of a horizontal tread for foot placement and a vertical riser that provides the height between levels. In outdoor environments, they are essential for bridging changes in elevation, connecting different areas of a landscape, or providing access to a building's entrance. Exterior steps must be designed with durable, weather-resistant materials such as concrete, stone, or treated wood and often feature anti-slip surfaces and specific drainage considerations to ensure safety and longevity under various environmental conditions.
Structural & construction notes
Common types of exterior steps include permanent hardscaped steps made from stone, brick, or poured concrete, as well as structural deck and porch stairs constructed from wood, composite, or vinyl. Other specialized varieties include garden pathway steps that follow natural contours, space-saving spiral staircases, and functional mobility or portable steps designed for specific accessibility needs. Common materials for exterior steps include pressure-treated wood, cedar, redwood, composite decking, metal (aluminum or steel), concrete, and various natural stones like granite and limestone. Wood and concrete are budget-friendly but require regular maintenance or removal of old structures, while composite and metal offer high durability and low maintenance at a mid-range to high cost. Natural stone, particularly granite, represents the highest initial investment due to material costs and labor-intensive installation but provides exceptional longevity and aesthetic value.
