Does blender have a layout system for architectural modeling? I just started a modern house project and I want to start with a layout of the house. Is there any feature in Blender that basically lets you draw your layout? 

(Sorry if this question is a no brainer, I am new to architect in Blender)

Thanks in advance
Use the Archimesh addon. It is included as part of blender just needs to be enabled in the System Preferences window.

As described in the github page:

Is Blender add-on for creating architecture elements:
Rooms, Houses, Columns , Stairs, Doors, Windows, Tile roofs, Kitchen cabinets, Japanese curtains, Roller curtains, Venetian blinds, Books, Lamps
