Terrace

Definition

A terrace is an outdoor, raised, flat platform structurally associated with a building or landscape, designed to serve as an extension of living space for leisure activities like dining, socializing, or viewing the surroundings. Often larger than a balcony and typically open to the sky, it can be located at ground level, on an intermediate floor, or as a rooftop area. Terraces provide a functional transition between interior and exterior environments and are constructed from durable materials such as stone, brick, concrete, or timber.

Structural & construction notes

Common types of terraces include ground-level garden terraces, raised or suspended terraces on stilts, rooftop terraces, and apartment terraces integrated into building floors. In landscape and agricultural contexts, they are categorized into broad-base, channel, and bench terraces designed for soil conservation and water management. Architectural variations also include specialized designs like the Venetian altana or Thai chaan, as well as structural configurations such as longitudinal, diagonal, or cantilevered terracing in multi-storey buildings. Common materials include natural stone, concrete pavers, brick, wood, composite decking, and porcelain tiles. High-durability materials like stone and porcelain have higher initial costs but offer the longest lifespans and lower long-term maintenance. Budget-friendly options like gravel or poured concrete reduce upfront costs but may require more frequent upkeep or may be prone to cracking in certain climates, affecting their overall durability.
