Looking for design-advice

If all those SpotLights cast shadows, your map is going to be quite laggy..

Aside from some errors like how you built the stairs right into the floor and that welder doesn't really make sense there.. just use a mansion doorway. You may have to adjust the door a bit, but I don't really see no problem as long as you get that stone wall out of the room.

Thanks for the constructive criticism.

The SpotLights don't cast shadows.
I made a welder, because otherwise you open the door and theres directly a stair.
I'll probably just make an extra map for this building. With the default mansion wall, it looks very odd.
