About Us
With decades of hands-on experience, Greentop’s founder, John Roberts, is a highly recommended garden designer with a background in civil engineering.
He has been designing and building gardens across Cardiff, South Wales, and beyond, with a focus on creating beautiful, lasting spaces. He loves working with people, helping them to visualise their projects with accuracy and clarity.
Alongside his landscaping work, he’s become a trusted voice in the industry, sharing practical advice through YouTube long before it became the go-to platform it is today. His mission has always been simple: to raise standards, support others in the trade, and help anyone – from businesses to first-time DIYers – make the most of their outdoor spaces.
