A method of modular pole construction an elongate modular pole structure is disclosed. A first step of the method involves providing hollow tapered pole section modules, each module having a first open end and an opposed second open end. A cross-section of the second end is less than a cross-section of the first end. The modules are stacked to form an elongated modular pole structure of a selected length by mating the second end of a first module with the first end of a second module. The first and second modules may have different structural properties, such that poles having desired structural properties can be constructed by selectively combining modules having differing structural properties.
