Here are the pictures of your dutch oak hardwood sleepers that I used on a project. I'm very impressed with the aged appearance they have .
RAILWAY SLEEPERS USED
Grade 1 Dutch Oak railway sleepers
2.6m x 250mm x 150mm approx
It's great to see your finished project. The way you've used the reclaimed railway sleepers to form a low 'castle topped' wall that retains the planting around the patio is really effective. A nice design, that creates a beautiful space to sit.
