12-14 New Fetter Lane is a multi-storey office tower populated by an international law firm. Occupying a triangular site in City of London, the 15-storey scheme was completed in 2015. At the time of completion, New Fetter Lane achieved BREEAM Excellent with a score of 76%.

The scheme utilises solar panels at roof level to pre-heat the domestic hot water, enhanced on-site ecology and increased levels of fresh air to improve health and well-being.

In 2017 XCO2 undertook a Post-Occupancy Evaluation (POE) of the building in order to understand how the building is performing in relation to its designed performance.

The study aimed to improve the ongoing environmental performance of the building as well as feedback lessons learnt for future GPE developments.
