I was concerned about the state of Rock House, or at least its southern half, the last time I took a closer look at it while passing. Happily it seems to have been bought by someone prepared to fix up that drooping balcony. Here's hoping these repairs continue and my next photo of the place shows both sides of this old house (dated back to at least 1731 by a William Halfpenny engraving, no matter what the Listing says.)

Just behind Rock House you can see a bit of the Colonnade, sawn off at the end to make room for the widened Hotwell Road, I believe. Back in the day, according to 1925's The Bristol guide; being a complete ancient and modern history of the city of Bristol, the Hotwells and Clifton:

For those who prefer exercise to silting, there is the Colonade with shops, built beneath the rocks, and a parade about
800 feet long, shaded with trees, by the side of the river, so that the company may enjoy a dry and pleasant walk when it rains, or an airy, cool, and shady walk in the warmest season: also during the influx and efflux of the river, they may be entertained with the sight of the Merchant's ships, Steam packets, and Coasting vessels that generally pass up or down.
