Create a 3D background for 360 equirectagular image based on this stock image

Hi, we are creating a Three.js 360 spinner and need the background for it. We have a flat image which we need you to 3D model, light and render out to be used here https://threejs.org/examples/webgl_panorama_equirectangular.html

It is an empty room, exactly same as this image attached, but with both sides same. https://www.dropbox.com/s/jhjzdsprc9s48rc/shutterstock_1193111521.jpg?dl=0
