Inside Storeys. The People behind 103
“When you have worked on a project, be it on the demolition or the construction, when the building is finished you get a real sense of job satisfaction, knowing that you have played a part in something that will be there for years to come. I can’t say I’m a fan of Brutalist concrete buildings, so taking the Natwest Tower down was actually quite enjoyable. The new 103 Colmore Row building will be a fantastic addition to the city skyline.”
