The student team at Park Lane College - now part of Leeds City College - has designed an outdoor room that features water conservation elements and a pergola.
The 28sq m garden, Bustani Ya Kenya, has been designed for a fictional accountant, his wife and three grown-up sons, living in a town house in Harrogate. It will be exhibited on 19-22 April.
Student Gary Gillings said: "We wanted it to reflect the family's need for a space they could use to entertain friends in a relaxed setting.
"The decks and pergola combined with an entertainment system provide the perfect environment to view the plants that reflect the family's passion for the regions of Kenya."
Other colleges taking part include Askham Bryan, York; Bishop Burton, East Yorkshire; and Craven College, Skipton. The University of Lincoln and Nottingham Trent University will also be there.
