I think that the description in the ad changed a bit. Now the thing is supposed to be still in Lowestoft but the location on the map places it between Norwich and Lowestoft.

Based on the interior pics on the google ad, looks like a pending fire hazard....

I haven't seen it, and I live in Norwich. I shall have to go and look around, though I would not want to waste too much time on this awful thing.

There are some info in the description section of the ad. The ship is new, built three years ago and in the water for about 18 months. It seems to be in Norwich now.

Hadn't spotted that!
But now found this:

The ad is rather confusing - sounds like the boat is divided into sections - like flats in a building. The 9 photos do not seem to be linked properly, but if you google ["amazing spaces" "lowestoft" houseboat] in images, they all come up.

Presumably had a running crew when towed away (2 liferaft canisters, and anchor looks like additional for voyage)

There seems to be a "For sale" sign on the railing at the end of the bridge.

I have uploaded a photo I took in 2016, when she was still ashore. I could find no name on the vessel

It there, in a slightly different position, on Googlemaps also: https://tinyurl.com/y289ej89

Yes, it indeed looks like the blue hulled vessel. Distinctive bow.

That's such an interesting photo - probably taken in 2017 (certainly not before mid-2016, due to the tug EMS BOXER's presence)

Seems that this thing was recently refitted. I am quite sure that it is in this picture, on the slip. It appears that it received new widows and a false paddlewheel cover.
