Before I move any actual furniture, I always test me design in digital. I Measure the room’s dimensions, noting the location of windows, doors, heat registers and electrical outlets, then draw up a floor plan using my computer software to draw the space and test various furniture configurations.
I will decide if I want a symmetrical arrangement if its a formal room or Asymmetrical arrangements to make a room feel more casual. I will place the largest pieces of furniture first, such as the sofa in the living room or the bed in the bedroom.
Here are some pictures of a resent furniture installation showing how smooth setup can be if planned.
