Two large, and not much loved, office blocks that stood at Euston station have been demolished to make way for the new HS2 station.
They’ve been under demolition for some time, but the process reached the ground level last week, marking the completion of that phase of the demolition works. To enable the demolition to be carried out, the buildings were covered within an acoustic wrap, and then excavators with breaking and munching attachments worked down the building from the roof demolishing floor by floor.
The final stage of the works was to demolish the huge 2.7-metre thick One Euston Square first floor slab. This was completed in two stages. Firstly two 45-tonne excavators with breaking attachments were lifted on to the slab with a 450-tonne mobile crane. These machines removed 60% of the slab working from the top. Once complete they were lifted down and the works were completed using a 45-tonne and 60-tonne excavator from ground level.
To cut down on lorries, a lot of the waste is being reused on-site to build the new station rather than being carted away for landfill.
The two old office blocks were designed by the modernist architect Richard Seifert, and were supposed to be part of a larger office development in the area, but plans were changed in the late 1970s, leaving just these two monoliths standing alone.
While much of Seifert’s work has been positively reappraised in recent years, these two dark grey forbidding looking rectangles never gained many fans.
