Circular stone paving and seating terraces in the Aga Khan Garden, Alberta. Source
Description
A stone patio provides a paved area for sitting, gathering or circulation. Stone dimensions, laying pattern, joints and edges contribute to its character. Its levels and supporting construction connect it to buildings, paths, steps and planting.
History
Paved terraces form part of established garden design, providing defined places within planted landscapes. Contemporary projects continue to use stone paving to organise movement and gathering, adapting its construction to the site.
Commissioning
Use, levels, drainage and the supporting build-up should be agreed with the designer or installer. The stone and finish need to suit exposure and walking conditions. Thresholds, paths and steps should be included in the design of the complete installation.
