Dungeons? Gold? Your computer might be the next gaming hit complete with mini-quests and hours of game play: Terrace House - The Lost Model. I replied earlier but it looks like my reply was consumed by the blackhole of internet problems.

Funny thing about me and interiors - I lack ... spatial visualisation. (Some say it's because I'm girl; I say it's because nobody told me geometry was meant to be real world practical and not Art for mathematicians).

So I struggle with envisioning what the inside layout of buildings are supposed to be.I like buildings with interiors, but I think I'd actually prefer floor plans, so I can do the interiors separately. I can work with floor plans. Prop Windows/Doors or at least mat zones make my life easier. (This is just an FYI on my views on buildings in general - not my demands)

I tend to brute force it a bit:

Using  the Terrace Shop as an example:

Looked at the windows and doors to see if they'll be a problem. Sometimes they are period specific, and I don't have alternatives to replace them with, and therefore I can't build an interior.

In my case, I can make the interior shots focus on the aisles and the counter, so I can eliminate camera angles that would show the windows or doors, so I don't have to replace them.

Potential  interiors (cheapest to priciest): DarthJ 50s Interior, DAZ Sweet/Magic Shop, DAZ mercantile interior, Meshbox The Store (Versatility of Bundle),  Rendo Boutique (3-D-C)

Mentally visualise workflow: Load model, load walls, place walls around the room  (one From the bay window to corner, intersecting  with one to the end of the upstairs floor, and completing the square)

Initially I thought the counter was on the far inside  but then decided it would probably be to the right of the doors, so that the shopkeeper can keep an eye on the customers by the entrance.

Noticed the window on that wall has grown bigger in the latest image, so counter goes back to the far inside. And have to figure out where to put the stairs  to the upstairs floor.

After this preliminary evaluation, I decide whether the model is viable. Yes it is - and it enters my "get it" list.

Don't know if it's helpful feedback or not, and I speak only for myself.
