With laser measure we can get the plans as precise as you want. If measurements are extremely precise and walls are not exactly parallel, the plans will look off. You may or not want this level of granularity.
We can adjust our precision between approximately 1/4" to 1/16". If you have a preference for precision, please let us know.
