I would like to add another deck on the rear of my house, i though about attaching it to the house but have a few extrusions and intrusions that come in and out from the house through the rim board. (Main electrical wire, Phone line, cable line, Dryer vent, and the intake and exhaust for the furnace.) I though about making a the deck not attached to the house by having two beams running parallel to the house (free floating deck). Is there anyway to actually attach it to the house without interferring with all the instrusions and extrusions?
Thank you for the help!
