Lean Construction philosophy is increasingly being used by construction companies to improve their production; however, in this industry, such applications are most frequently in the construction phase that in the design phase. The purpose of this paper is to propose the necessary and customised tools for applying Lean concepts to the building project design management. As a guide, this paper uses the steps recommended in the Project Definition and Lean Design phases, based on the Lean Project Delivery System TM. It adapts each module application and selects some tools regarded as the most appropriated. These tools have been gradually implemented in the authors’ office – same that design and execute building projects - with encouraging results. Application of such simple tools has helped us to eliminate wastes and prevent redesign. Good design management improves building project productivity and quality in other phases of the project; thus it benefits design and construction companies, as well as consumers who purchase these products. However, we consider that one of the biggest challenges is to align designers with these principles and commit these professionals to apply them.
