I made a simple 3d model of the project and added the lighting. It just needs to get assigned materials and make adjustments and get renders. Renders doesn't need to be perfect except [login to view URL] are 3d file and photos of the actual area and the stairs that should look like.
You can add office chairs and laptops on the tables in the open space office area if you have pre-modelled objects but it's not necessary.
30-45 mins renders are ok. It's urgent.
