Looks like it was unsympathetically "re-modelled" at some point in the mid-20th century when Victorian architectural features were considered unfashionable and ripe for destruction. It's hideous.
The notion that it's "exceptionally well modernised" is ridiculous. The bathroom looks 15-20 years old. The kitchen is not only old, it's unfinished and missing trim pieces, and parts are unpainted. Decor elsewhere may be new but the quality of the finish is terrible. I love that little touch of brand new spotlights (aka new build pox) recessed into an old artexed ceiling.
The £400K asking price, on a street which looks like the value should be £200-£250K at best, is the cherry on top.
