Two pipes

It does not look like a small house.. But it really is..

Here is the living room.

The wee wood stove in that corner.

The kitchen....

The kitchen with the appliances and the sink under the window! You can see them right?

Here is the hallway. A place to hang coats behind the living room wall on the right.

A little alcove for a stackable washer and dryer on the left.

The bedroom, back door just to right out of the shot. Closet is in there on the left.

The den... Back door just to the left out of the shot.

The bathroom....

The bathroom with piles of sawdust in the right spots....for the bath and the shower...

Now outside you can see the drainage pipes. 

According to code nowadays, the downspout pipes cannot drain to the perimeter drains.

Thus the two pipes will drain independently.
