Street Furniture Design Trinity Street Furniture by Ipek Memikoğlu Trinity is a street furniture representing a world where adults, children and animals get together. The circular form and the arrangement of the seating units represent sitting, shelter and social communication or social distance. Unlike existing street furniture, Trinity is designed for people to sit, and for animals to have a shelter and to be fed. The solid and void surfaces help to benefit from daylight and provide shade that is suitable for summer and winter seasons. Concrete and iron materials are recommended due to their resistance to exterior conditions.
