A prefabricated elevator system in which all major components — hoistway structure, car, machine, and controller — arrive on site as factory-assembled modules that are assembled rapidly without traditional civil works.

Modular elevator systems represent a paradigm shift in elevator installation methodology. Unlike conventional installations requiring a concrete or masonry hoistway to be built by the main contractor, a modular elevator delivers a self-supporting steel hoistway structure that stands inside or alongside the building. Key advantages: (1) Speed — installation of a 5-floor modular lift can be completed in 1–3 days versus 4–8 weeks for a conventional installation; (2) No shaft construction — the modular tower replaces the civil hoistway, reducing building works; (3) Factory quality — all wiring, rail alignment, and mechanical assembly is completed under controlled workshop conditions; (4) Minimal disruption — particularly valuable for retrofit installations in occupied buildings; (5) Relocatability — the structure can in principle be dismantled and relocated. Products such as the Schindler 3300, Kone MonoSpace, and Otis Gen2 use modular concepts to varying degrees. The EN 81-20/50 standards fully apply to modular elevator products. Installation planning requires structural engineer approval for the building's ability to support the modular tower base loads.
