Construction work continues on the London building that will eventually house the Regent Street Apple retail store. Workers replaced a huge, historic dome onto the roof of the building on April 19th, after it was taken off and stored last year. The four other retail tenants of the building have not been confirmed yet, but construction on the building itself is five weeks ahead of schedule, according to The Crown Estate. The building will also house 10 residential apartments and 100,000 square feet of office/commercial space.
