This project consisted of a new hotel and apartments on the site of the Ministry of Defence Old War Office in Westminster.


The construction please of this development presented unique challenges due to the requirement to retain the original façade of the old war office building.


Key design and detailing features include –

  • Evaluation of structural and fire models for vertical and raking columns

  • Strict transport and lifting procedures due to limited access and storage

  • Double raking columns including bespoke profiles


Due to the site location and restrictions Oran Precast adopted a just-in-time delivery system for this project. This system ensured our deliveries coincided seamlessly with the main contractors site programme.


In total 435 precast columns, 51 precast flights and 4000m2 of precast twin wall were delivered to site over an 11 month period.
