Curved Brick Wall
How to build a retaining wall with railway sleepers?
retaining walls sleepers - I like this better then bricks.
Small Sloping Garden Design
Put bug hotels in raised bed walls instead of gabions.
I like the idea of using curved edges to stop the garden looking to blocky.
Could add a completely different level on TOP of the concrete yard at one end, for a separate area feeling. Raised planter large enough for anything except trees. Beautiful.
Combined curved steps and retaining wall
Love the red brick raised border, perfect for our victorian terrace
This is what I would replace the railroad ties with in the back yard...if I won the lottery. :-)
