Working for Millers Mutual, we completed the office extension/conversion project at 21 Arlington Street.

The work comprised the conversion of existing vaults beneath the forecourt of the office block, into additional office space.

The floor of the vaults was excavated to provide adequate head room within the new areas. The layout was re-configured by the introduction of new Lunette Vault Brickwork to accommodate the new office space. New M&E services were also installed. A new Portland Stone spiral staircase was constructed from the underground vaults to street level, requiring a piled reinforced structure to create a new circular stairwell at the front of the existing vaults.

The construction site at Arlington Street is located adjacent to The Ritz Hotel. The main offices have remained occupied throughout works, with the only access/egress for the office workers being across the operational site, requiring the provision of safe walkways throughout works.
