More potential lettings are on the horizon for Colmore Plaza - one of the key buildings in the transformation of Birmingham's Colmore business district - which was officially opened yesterdayby the Leader of Birmingham City Council, Coun Mike Whitby.
Chartered quantity surveying practice Davis Langdon is the first tenant in the new building, which at 307,297 sq ft in size is Birmingham's biggest ever single speculative office scheme.
It will occupy the entire first floor - in size 23,000 sq ft - of the 14-storey building, which has been developed by Abstract Land on behalf of US investment giant Carlyle Group.
However, sources yesterday indicated that Carlyle is now involved in negotiations with a number of other interested parties which could lead to the letting of one or possibly two more floors of Colmore Plaza.
No official comment was available. But Barclays is known to be looking for around 100,000 sq ft of space to consolidate a number of its operations into a new city centre base in Birmingham.
It is understood to be eyeing either Colmore Plaza or the nearby Snow Hill scheme being developed by Ballymore.
Meanwhile, Coun Whitby raised a glass of Champagne to toast the success of Colmore Plaza, described as the first ever office building of its type and quality to complete in the city.
"The launch of Colmore Plaza is significant to the city and contributes to the £15 billion worth of inward investment," he said.
"This furthers the reputation of Birmingham as a centre for business on an international scale and is set to attract further regional and inward investment."
Mark Harris, director of the Carlyle Group, said: "Colmore Plaza is one of the biggest office schemes of its type outside central London.
"The high quality office space significantly contributes to the profiling of the city and represents the growing requirement from the professional community who are moving to Birmingham.
"Business occupiers will benefit from the large open floorplates and the underground storage provision which maximises the available workstation space on each floor.
"The completed building has all the features necessary to meet and even exceed occupier needs, including 'intelligent' technology and innovative designs that set the building apart from the current marketplace offering."
Colmore Plaza features floorplates of 23,000 sq ft, which can be subdivided by up to four.
The use of floor-to-ceiling glazing provides occupants with uninterrupted panoramic views over the city.
It is also claimed to be the city's first "intelligent" building.
In the impressive double height reception area guests will be welcomed with what is termed "destination call technology" which remotely reads personal identity cards for key facts, such as location of workspace and access restriction, before linking to the eight-strong lift system which is programmed to transport the passenger to the correct floor.
