The bathroom in the Scully home features a sink and floor made from travertine rock.
The couple said they also needed to undergo a review process through the city because the home is located in the historic district.
Homeowners in the neighborhood created the district in 1995 through a petition drive, said Nancy Burgess, historic preservation specialist for the city. Most of the homes on nearby Pleasant Street are listed on the National Register of Historic Places, meaning they are at least 50 years old.
However, the Scully house does not enjoy the register designation because the house underwent numerous alterations over the years before the couple renovated it, Burgess said.
The Scullys still needed to go through a design review process through the Prescott Preservation Commission, Burgess said. The City Council appoints the commission members, who meet once a month.
"Basically, the plans that (the Scullys) submitted for their building permits had to go through the approval process," Burgess said. "There is no extra fee, and they had a lot of other issues that had to be resolved outside of the historic aspect."
Those issues involved added square footage, lot coverage, setbacks, parking and concerns of the neighbors, Burgess said.
"I worked with the Scullys from the very beginning," Burgess continued. "They just had a lot of unusual things to deal with on that particular piece of property.
"Whenever you are deal ing with a historic building, you must adapt plans for the addition and remodeling," she said. "You already have something on the ground that you have to work with. And you have things that you don't know about until you tear into the building."
Mike said the "hardest thing" during construction occurred when he found out the soil underneath the house contained caliche or clay.
