the question is, how are you going to bring it into a completed house? it's a single piece

y amang... ayam surprised. i know istana negara and brunei sultan got escalators inside

Well,
Elevator send in to site with hundreds to thousands of losen parts.

Just for the cabin itself, it can be detached to at least 6 panels, 1 Control panel, 1 overhead ceiling, platform, header case, plank, side arm, door panel, door machine, etc

Then u need a counter weight that can dettach to frames, weight, n sometime wheel. If canti-level that the wheel can be void.

After that the houst way, the guild rail can be dettach to 2, 3, n 5 meters long depends on requirement with some small accessories, connecting plates, & hoistint cable.

Then machine room consist of a motor, a sheave wheel, & platform/bed to let your motor sit tightly.

Then we talk about Control System. It can be integrated into the hoistway if the elevator is compact or motor-roomless design.

Installation wise needs at least 2 workers to install everything and 1 wiring man to setup the wiring.

The installation is quite simple. I can do it myself with my bangla worker n wat we really need is, energy.

Maintenance wise, u can hire maintenance guy for RM300 a month for 5 floors elevator (3 yrs ago pricing). Just normal servicing like check cable, lubrication, ini itu.

The raw cost to build a 8 person lift for 5 floors with motor-roomless design is about 50~70kRM (when USD = 3.5RM).
