Built my first home after almost 3 years non play

Your new home is lovely! :) It is great that you are back simming again! Very nice layout of the interior, and the wall colours and patterns in the rooms are very nice. The floor rugs add a nice touch to the living room, study and kids bedroom. Very nice study for Sims to enjoy sitting at the desk tables using the computers, or resting on the sofa reading a book. The floor tiling in the kitchen is very nice, and nice floor patterning in the bedrooms. Very nice fireplace sitting area in the living room for Sims to enjoy watching tv or reading a book in front of the fire. Kids will enjoy doing artwork on the activities table or using the build blocks table.
It is a very nice family home :)

@Romire You get the concrete off by clicking it in build mode and choosing "remove floor". For some reason the game thinks it as a room... maybe you build it with a tool that auto-creates a foundation...
