Detail Design is an upcoming text book authored by Brook Teklehaimanot and Tibebu Daniel. The book is meant to be a text book for 3^rd and 4^th semester Design Students. The course for both semesters is thematically organized on the ‘detail’ both in its theoretical notion as well as its practical meaning in the making of Architecture. How does one conceive a detail and how does one make it? A pedagogical approach of exploring details from current and contextual Ethiopian society artifacts is chosen so as to make students keen to their physical and social environment. A particular detail is extracted from these artifacts and goes through different processes of design where it is synthesized, mutated and finally integrated to make a holistic piece of Architecture. The textbook will be published in 2020.
