Here's the front - white columns fading into fog. Kinda haunting, kinda fancy.

The pond is still, lilies just hovering. Koi in there or nah?

Okay, this facade - pristine white, big symmetry energy. Not sure it needs more.

From above, the lawn goes forever. Tiny driveway, massive house flex.

Old bones in the fog. Feels history class with jump scares.

Here's the entry - curved staircase, glossy wood. Feels a movie set.

Green velvet walls and sneaky gold pattern. Anyone else getting theater vibes?

And then the ceiling goes coffered. I mean, it's gorgeous, maybe extra?

Soft beige, carved ceiling, a little rustic. Cozy without trying too hard.

Those Corinthian columns are doing the most. Who dusts all that carving?

Back outside - misty path, light sifting through. Instant screensaver mood.

Here's another wide shot. columns ghosting out of the morning haze. Dreamy.

Closer view of the mansion - white disappears into fog. Spooky, but elegant.
