I carry them in a black MEC knapsack.

.
The shoulder straps can fold away so it becomes a briefcase... It also has padding for my laptop.
Edit: The worst place I have ever lived... it was an apartment in the depths of Scarborough (Mornell Court for those who know the area). It was nice when we moved in but 8 years later, not so much. One night, there was a murder in the building and the murderer committed suicide in stairwell not 10 minutes after I had just walked my 10 year old self down the stairwell.
We were happy to move.
How far do you live from work and how long is your commute?
