 The castle's former walled garden with its sundials and complex flowerbed layout is now occupied by a housing estate built in the late 1960s, but a single wall of the structure still remains.In the 1850s an orchard is shown on OS maps, located next to the walled garden.A cobbled ford once crossed the Stevenston Burn in the Kerelaw Glen beneath the castle and ran up the bank passed the Kerelaw Mains home farm.
