This view of the house was too long that I had to take two shots of its sides plus what was at the bottom. Also, most of the information from the bottom pic was already said from the Romney Manor information board picture, so I'll just type what the middle says.

"The house has changed many times over the centuries. The original foundations are very evident with their uneven stone work. Additions are clearly visible with clean cut stones and some "style". Note the staircase and rear of the building."
