A cooperative agreement was drafted between the land owner, a real estate agency, and the project designers to sell three ocean-front apartments in Punta Hermosa beach, Lima, Peru. I collaborated with a colleague and we both agreed on a concept which led to the design of spatial and functional distributions, structural, electrical, and sanitary systems, and estimated costs. Furthermore, we obtained the construction license and developed all technical specifications. Lastly, we supervised the construction and delivered apartments to prospective owners as approved by the municipal board of reviewers and the owners themselves.
