"Landscape architecture is often known as a four-dimensional design discipline," said founder Lionel Fanshawe. "The fourth dimension, time, is often overlooked. But a landscape scheme is very likely to reach its desired effect many years after completion and even then it will never be static."
Grasping, foreseeing and managing likely outcomes over time were talents a landscape architect needed to nurture, he added.
The practice, based in Petersfield, Hampshire, with a Dubai office, marked its quarter of a century with a booklet to "share reflections and explore this fourth dimension".
"This booklet is both a celebration and reflection on the passage of time, continual change and the need for optimism," he said.
Fanshawe's team has worked on landscapes such as Tittenhurst Park in Berkshire and masterplans including East Beach at Salsey.
