This scheme involves the refurbishment and extension of an existing 14 storey office building on a prominent site in Archway, immediately adjacent to the TfL station and the Northern Line below. Previously occupied by mainly office use, this 1960’s concrete frame is to be re-clad and converted to residential apartments via permitted development rights. Further studies are underway to maximise the potential of the building and site.
In the absence of any detailed historic drawings HTS have back-calculated the capacity of the existing structure to confirm the viability of architectural proposals to redevelop the existing tower and plinth.
Existing piled foundations were investigated on site with specialist ‘parallel seismic testing’ techniques to prove the capacity of the foundations for the development. Reinforcement within the existing concrete frame has also been exposed and samples tested to allow us to understand the specific material strengths of the building.
The scheme is part of a wider ranging masterplan for the island site covering five or six other new buildings for which HTS are also helping to prove the viability. Works on the conversion of the existing building started on site January 2015.
