The cost can be affected by the size and height of the wall, the materials used, site access, and any additional drainage or finishing requirements.
Yes, retaining walls are subject to Building Regulations if they are over 1 meter high and adjacent to a road or path, or over 1.5 meters high elsewhere. Always confirm with your general builder before work begins.
Common materials include concrete blocks, bricks, natural stone, and timber. The choice depends on aesthetic preference and structural requirements.
Drainage is typically achieved by installing a drainage layer and weep holes to prevent water pressure build-up behind the wall.
