Aft Well Deck fig 1  (Click here to view a Titanic/Olympic version of this drawing)
The most apparent difference between the sisters is the cover which Britannic sported, but which was absent on Olympic/ Titanic. This is why Britannic has the unusual stanchion arrangement in the aft well deck hull cut-out. A less obvious but critical difference in this area is the addition of a fourth expansion joint, running between hatches 5 and 6. The hatches themselves were extended upwards above the new cover.
You will also notice that the two cranes have been moved up a level - on Britannic they sat at the same level as the ones on the poop deck. According the rigging plans they would, however, have been stored in the same angular configuration as they were on the sisters.
The drawing of Britannic shows clearly a number of new staircases which were unique to Britannic (although some were added to the late Olympic). Two of these allowed access from the aft well deck cover to A-Deck, and the other one allowed access from A-Deck to the boat deck. No doubt these were added a safety measure to enable passengers (regardless of class) to easily get from one place to another in an emergency.
Perhaps one of the most interesting changes shown by the above pictures is the difference in deck shapes employed on Britannic. You can clearly see the "simplified" shape of the A-Deck aft edge, and the regularized straight edge of the Boat Deck.
This alteration of the A-Deck aft edge led to the repositioning of the #4 hatches. Instead of being flat into the deck, they now had a bulkhead around them and a pair of large double doors facing outboard. How cargo would have been loaded into these is unclear; for some reason the A-Deck cranes were omitted from Britannic.
The final and most intriguing (and difficult to spot) changes is the fusing of the #2 class entrance at B-Deck with the aft side of the A-La-Carte Restaurant.

Bridge Area fig 2
This bridge area drawing shows yet another vastly different area on Britannic. Things to note in particular are the gantry davits and their associated operating gear (the port side davits were left off the HMHS configuration due to time limitations), massive stack of lifeboats and the canvas "box" on the bridge roof. The exact purpose of this "box" is unknown - it may have housed an extra, wartime, Morse lamp or it may have contained an auxiliary compass. You should also pay attention to the vents immediately in front of the #1 funnel - these are drastically changed from those found on Titanic or Olympic. Finally, a subtle difference is the extension of the bridge side bulkheads. Whether or not these would have been in place on the final ship is debatable. The plans seem to show them longer than the ones on her sisters, but they would therefore have caused an unnecessary obstruction to the officers' field of view.

Forward Well Deck fig 3
The forward well deck is one of the best known alteration areas on Britannic. Following the Titanic disaster, the steerage passenger's were going to be treated somewhat better on Britannic. This involved giving them proper, enclosed entrances in the forward well deck which lead to the 3rd class recreation areas below on D-Deck. These entrances weren't quite as wide as the hatches, and featured double doors in the port facing bulkheads. Another feature is the addition of extra mushroom vents - Olympic also had a few of these added later on, probably to better ventilate the 3rd class areas below. The final two features to note are the fairlead rollers moved up on to the forward entrance's roof, and the two winches which have also been relocated.

1st Class Lounge Raised Roof fig 4
The area around the #4 funnel on Britannic is almost certainly the most impossible area to understand on Britannic. Overshadowed by 4 huge gantry davits, each holding a full set of boats, it is virtually impossible to see the detailing in this area. There are also very few photographs taken specifically of this area. With this challenge in mind, Remco has drawn a superb view of this area, minus the davits and boats. Drawing from data supplied by Russell Wild and Dan Hughes, as well as his own research, he has done his best to surmise what this area would have been like. Things to note are the vents and staircases. The large flat rectangle shape to the aft of the deckhouse is the raised section which houses the "soffit" in the lounge below.

A-deck partition  fig 5
This drawing shows the A-deck partition as it was on Britannic. The straight partition, with it's two doors, it's a real difference compared to the one on Titanic; this partition had one door and one window and was shaped like a gull's wing. The drawing is based on a photo that was shot by the 1999 expedition and on Britannic's builders plans.The brown colour on the back of the door is not sure, it might also be white. The door on the left is crew stairwell door, which leads you to the boatdeck.

One of the extra luxuries added to Britannic was the Children's playroom, almost a mirrored copy of the gymnasium. This playroom was a bit shorter then the gymnasium, note that there's a small overhang at the aft of the playroom. Other things of interest: an extra expansion joint, the elevator gear house and vent placements. When this drawing was made, the area aft of the gymnasium is a bit unclear in the case of vents; this might be different then what is shown. The drawing was made with help from Dan Hughes and Mike Pell.
