Those pictures look like the originals used in the first plan to partially demolish, and then restore the building to its "original" state. Not opposed to the look of the building at all.

In fairness, over recent years the building and gardens had become very run down, so a fresh replacement should brighten the place up.

I will try and get a sneeky pic or two next time I'm passing.
I do know the perimeter of the site was piled, and excavation is now underway for most of the site. From the original front of the building, to the rear of the garden.
