Presumably one of the units has been let and it's fit out time ?
On a different subject, the L&G extra jobs potentially coming ot the city has made the Western Mail today
http://www.walesonline.co.uk/business/business-news/legal--general-create-up-9926552As usual the article brings up the subject of their office requirements, see below
"The expansion could also bring to a head L&G’s long-term property requirements in the capital.
It currently has short-term leases on office space at Brunel House and the nearby Knox Court.
L&G has in the past been linked to a new 100,000 sq ft headquarters in the city, including for critical systems security reasons, potentially two separate locations of around 50,000 sq ft each. But it could also opt for a single building or take on new space at its existing locations, where it has to give two years notice to exit its leases. L&G is being advised by the Cardiff office of chartered surveyors Knight Frank."The main thing is that there's a decent chance of a few hundred roles being created in the city, whether through relocations or brand new jobs, but based on what someone else (seemingly in the know) said above they are probably just taking existing space. There's nothing in that article to suggest otherwise.
