I used the Android app magicplan, and was pretty happy with it. I had to do some manual cleanup in a couple of places, but it's free to try out and only costs a couple of dollars to open it up so that you can export your plans. Best of all (for my purposes) is that one of the formats it can create is SVG, which means that with the help of Inkscape and the Home Assistant FloorPlan plugin, I now have an interactive floorplan running on a wall mounted tablet.
I've used magicplan. It used to require calibration, but now it seems to be just "point at floor" then you walk around telling it where corners and doors are.
LPT: use magicplan (This link is for the Android app, idk about Apple users)
I have my current floorplan and all my furniture measured on it, and just move my stuff around there before doing so IRL.
It's also been surprisingly convenient now that I'm apartment hunting again lol
I can only afford tiny places and it's very cool to have the apartments mapped out on my phone complete with windows, doors and power outlets, so i can see which one will be more comfortable to live and fit my stuff into.
You could take lots of photos and use photogrametry to recreate it, using something like Agisoft, then use Unity, SteamVR and the VRTK to get the model into VR and add interactions.
Alternatively you could use MagicPlan to create a floor plan: https://play.google.com/store/apps/details?id=com.sensopia.magicplan
You could then import it into SketchUp, use the scale tool to properly size it, create the mode, texture and populate it, then save it as a skp file. One done you can then directly import the skp file into VR using Symmetry Alpha, which is free and will let you teleport into and around your model, plus allows re-texturing and adjust for time zone and time of day: http://store.steampowered.com/app/585340/SYMMETRY_alpha/
Not the same app but I tried an app called magicplan that was good enough for me.

You can add furniture and things too which is what I plan on doing for this currently empty room.
You basically walk around and point your camera at your room using AR to set the corners and things and then do a little adjusting. This took me maybe 30 minutes total to get the hang of it but I could do this again in 5 now. It might be easier on the iPhones with lidar for depth mapping but on my phone I just had to go slowly so the app doesn't lose track of where it is.
The free version has some limitations but I think for an apartment this should be good for the whole place
There are apps on playstore for estate agents and interior decorators https://play.google.com/store/apps/details?id=com.sensopia.magicplan
Use with chaos engine and Apex. Message me I need a colleague
See my other comment.. I'll ask my other half when we get home..
Edit: Apparently she used MagicPlan but it wasn't great, a tad slow and assumed right angles (you know, as you do..).
Google turned up MagicPlan, there was also a few others, but this one seemed to be better reviewed.
Here is the android one: https://play.google.com/store/apps/details?id=com.sensopia.magicplan&hl=en

https://play.google.com/store/apps/details?id=com.sensopia.magicplan Give magicplan a go. Should be able to sort something out for yourself with it. :)
Closest I could think of would be Magic Plan

Apps and programs
Sometimes the tendency is to "knock this down and then we'll deal with it." Yea, not a smart idea. Creating a clear and concise vision will prevent wasting your money, and your time. Look at some of these:
https://en.homedesign3d.net/ Home Design 3D is robust software that has a gentle learning curve. You can start your dream reno the same day you download it. You will find it easy to use, and easy on the wallet, at a whole whopping $12.
http://www.sweethome3d.com: It is open source software that can be downloaded or used online in your browser. Available in 27 languages, it boasts an impressive host of features. Well worth looking into.
https://www.homediary.com: Is a Flash based program that may possibly be the easiest one to learn. It also can store inventory and maintenance records, and allows you to clip ideas and create reminders.
https://www.sketchup.com is freeware for personal use. Has a lot of users, and is evolving constantly. It seems to have a greater learning curve than the first three offering, but this in no way should prevent you from checking it out.
