Can anyone recommend any companies that provide a service to create floor plans of an existing house including nternal room dimensions, door locations, window dimensions and location plus the distance of the dwellings walls to the side/front/rear boundary? I wanted to use this floor plan so i can personally sketch on a garage and an alfresco (i dont believe i need a designer) and so i know exactly how big each room is so i can think about furniture placement. The floor plan needs to be good enough so i can submit to council for DA and shop around for a builder to get quotes. Im not sure if those companies that create floor plans for RE marketing will be sufficient as i believe some just use their phone with an app? I have done many developments but not major renovations. Is this the correct way to undertake such a process? Alot of the sruveying companies do not do internal measurements.
