How to Build and re-scale walls in runtime

Hi,

i'm very poor in coding and need some help here..

i want to add a square room and scale each wall with dimensions input, also want to resize them with anchor points.

somet$$anonymous$$ng like t$$anonymous$$s: is there any asset w$$anonymous$$ch allow me do all these in runtime? or, any inputs on positioning/scaling walls with their anchor points in runtime? All these t$$anonymous$$ngs, i want to do it in 3D (Basically, it can be cubes)
