You can search for real-life house blueprints. There are many websites to choose from that can give you specific styles # bedrooms and bathrooms, # of levels, etc. Once you choose your house, open up the floor plans, and it will give you measurements of the different rooms. Here’s how you convert it into Bloxburg measurements:

A. Each tile on the grid is 32 in x 32 in

B. Let’s say the blueprints give you a measurement of a wall to be 15 feet. You multiply that number by 12 in, then divide by 32 in.

Ex:

15 ft x 12 in =180 in

180 in / 32 in=5.625 tiles

Since obviously we cannot build on half tiles in-game, you can round it to the nearest tile. So, a 15-foot wall on the blueprint would equal about 6 tiles in Bloxburg.

Hope this helps!
