This document proposes a new technique for hollow ferrocement building construction that has several advantages: (1) It is easy and fast to construct, reducing time and costs; (2) It provides good sound and temperature insulation; (3) It allows for the reuse of solid waste like plastic bottles; and (4) It is environmentally friendly. The technique involves constructing a base wall, columns, and installing wire mesh on both sides of the columns before filling the walls with plastic bottles. It also describes the required materials, which include wood, wire mesh, screws, brackets, and plastic bottles, as well as the step-by-step construction procedures.
