Write a first-person walkthrough of 5 different houses or appartments in Unity3D. The houses need to have minimal furniture and lighting. Walkthrough is WASD and mouse for camera movement, relatively standard. The houses should range from 2 to 5 bedrooms, must have kitchen and at least one bedroom. Doors would be nice, but not essential. No interactions with doors is needed. Must have windows and lighting features but lighting can be faked.
You have lots of flexibility in terms of design. You need to submit the Unity files that will work with the latest version of Unity. C# is preferred, but other languages are OK. You can use free or paid assets in the house. This is for an internal demo, not a commercial release.
Timeframe is short. Preference given to people who can deliver within a week. If you have working demos of similar work that is a big plus in getting chosen.
