Reading is not a 'new University' in the post-92/former poly sense.
The campus is green and spacious (compared to a city-centre university like the one where I am now), but some of the buildings are fairly ugly, yes. Ugliness of buildings should not be a deterrent if the course and other things are good, though.
Can't comment on halls, as I was last inside one in the 1980s. [extreme old-age emoticon] Back in the olden-days, some were terminally grim (Childs, in particular) whereas others were better (Whiteknights was OK, Wantage was a bit Oxbridge wannabe). But this info is so out-of-date as to be pointless.
Not sure what subject your dd is interested in, but you can get decent info about how Reading fares in comparison to other institutions for this subject from some/all of the following:
Guardian University League Tables. These are largely based on evidence related to teaching.
The Times Good University Guide. These balance teaching and research evidence.
The National Student Survey. Responses from finalists about various aspects of their courses. Results by institution and by subject area.
RAE2008 The results of the 2008 research assessment exercise, which can tell you something about the standard of research in your chosen subject area and/or institution.
