The Yorkshire born surveyor is responsible for ensuring Grosvenor's projects remain on target, from design stage to completion.
"I joined Grosvenor 18 months ago and was delighted to come to Liverpool which is one of the most exciting places in the country in which to work.
"The completion of the first projects does not mean we can relax. We will start demolition work as soon as possible in
Paradise Street and in February we will hand over the new BBC studios in Hanover Street so they can be fitted out by engineers, ready for opening later in 2006.
"Grosvenor's Paradise Street project is the biggest scheme I have worked on, and far different from my original profession as a dentist. I gave that up after two years when I decided I wanted a career change.
"I then qualified as a surveyor and it is a job I really enjoy. Working in Liverpool is a bonus. The place is so beautiful and the people are so friendly."
Grosvenor project director Rod Holmes said: "We are delighetd to have Bill Allen as part of our team. He has done a first-rate job in making sure everything is on time."
