The addition that was added looks like it was an original build. You cannot tell that another room was added. It is exactly what we wanted and with a few minor hiccups the job was done with professionalism and attention to all the details. This room is on the second level and we also added a balcony. I would highly recommend Mario and his team as they get the job done with a minimum amount of disruption to your home and yard. Thanks Mario we are enjoying this new room every day!!
