Welcome to the Workshop community @Dev. Many thanks for your question, I'd be happy to assist.

We have a great range of treated pine sleepers which you can use to make retaining edging. There is also a system of simple to use sleeper pegs which hold the edging in place keeping it straight. 

If you wanted a less impactful retaining edging than the sleepers, I can suggest the 100 x 25mm 2.4m H4 Treated Sawn Pine.

You might like to take a look at @Adam_W's tutorial on How to build a retaining wall which you should find helpful.

For your irrigation system, this D.I.Y. step-by-step tutorial on How to plan garden irrigation will assist. What did you want to irrigate? Garden beds, trees, the lawn? If there are any specific requirements for your home's system, I'd be happy to give instructions on how to position and install those.

If you have further questions about the timber edging or irrigation systems, please let me know.
