"The original 16th hole was altered during the construction of the villas and the new tee on the roof is pretty much where the old tee used to be.
"We were able to get real grass on the roof and the tee is in good shape. It takes four men to lift a hand mower up the stairs to the tee. I'm looking forward to watching players head up there throughout the week.
"The raised tee really enhances the hole, gives the players a great view, brings the bunkers into play and looks great on TV."
The new rooftop tee box was received well by the players as well. Harrington gave it his approval following his practice round.
He said: "I like it. it is of interest to [the media], for us it is an elevated back tee. I suppose I've hit off the cliff, the Extreme 19th hole [at the Legend Golf Resort] in South Africa, that's a little bit intimidating but here it's a nice, elevated tee shot and it certainly adds to the hole."
The hole will play 34 yards longer due to the new teeing area and will measure 463 yards when used.
