Details for the landscape around a house. This category includes robust solid brickwork garden walls, solid brickwork retaining walls at different heights and depths, garden terracing with multiple retaining walls for steep sites, and garden wall steps with stone copings, using brick copings suited to simple free-standing walls.

Do retaining walls need an engineer? Usually, yes. The wall depends on the height retained, soil and water conditions and any loads above, so confirm the design with a structural engineer.

Do the steps need guarding? They might. Guarding requirements depend on the drop, so check the drawing notes and Approved Document K.

Is there a pack of these details? Yes. The Retaining Walls and Copings Detail Pack bundles retaining wall, terracing and coping details.
