Hi @Claire2024,
Thank you for your question and welcome to the Bunnings Workshop community, it is fantastic to have you join us.
For tools, I'd suggest at a minimum you'll need a drill, circular saw, tape measure and a stud finder.
You can then use CUSTOMpine 16 x 2400 x 1200mm White Matt Particleboard alongside some stayed brackets or timber cleats that will be screwed into the studs using Zenith 50mm Timber Screws.
Measure the space and cut your shelving to size. Locate and mark the studs with your stud finder. Attach your brackets or cleats to the studs and then put your shelving on top.
Let me know what you think and if you have further questions, please don't hesitate to ask.
Jacob
