Refurbishment & extension

Parmarbrook was commissioned by Criterion Capital to provide engineering services for the redevelopment of the island site at 125 High Street, Colliers Wood. The site comprises a 19-storey tower, with a six-storey extension, adjacent to the Northern line London Underground, to provide 218 residential units, a café, bar and amenities.

Situated over both direction tunnels for the Northern line, the site was essential to ensure the development had no effect during or after construction. Ensuring there was no transfer of load onto the tunnels either by keeping piles outside the exclusion zones or by ‘sleeving’ prior to piling. Infrastructure surveys and tunnel condition surveys were undertaken before and after the construction works to accurately locate the tunnels and check that no movement of the rails had occurred.
