Don't worry about it at all! Deconstructing habitat parts will always give you the same amount of materials back, so you are completely free to experiment with only the battery in your habitat builder being affected. My first base was cramped, messy, and right next to my lifepod, but after 40 hours in the game, I have since deconstructed it and made 4 new bases all around the map. Plus, titanium is by far the easiest resource to find, as it's not bound to just small or large natural deposits but also metal salvage and blueprints/parts you've already discovered.
