Great build! Really. One lesson learned, huge houses are huge on the outside not the inside, maybe if I follow that philosophy I can complete that monster of a mansion I built. Thank you.
You're welcome. My tip to you would be to divide the rooms and adding essentials such as beds, counters of a gym machine before you start decorating. It can be hard to keep focus on decorating the rooms when you have so many, so putting placeholders down to help you remember what the rooms will be for is a great tool to help you.
Also, don't be afraid to leave space for sims to move around and it can be a good idea to have at least one sim live on the lot while you are building. So that you can test if a sim can use an object asap. This is something I wish I had thought of...
