Looks like some good progress made on site last week. From what I can tell, Redrow have got to a milestone and all of the last phase have had their roof and windows installed and hence watertight.
Also noted on the Redrow website Abbotts Walk page, that there are no plots available with pricing (there has been a lone Buckley on there for a while). So that may well mean that all the homes have now been reserved..
[update 25/2/14] The development has completely dropped off the Redrow website now. You can see an old copy on the Web archive Waybackmachine: http://web.archive.org/web/20131022133930/http://www.redrow.co.uk/developments/abbotts-walk-winchester
