The MEP services were all replaced with a focus on energy efficiency using air source heat pumps, LED lighting and natural ventilation where possible.

Following the successful Cat A office refurbishment of the upper part of 33 Glasshouse Street, the second phase known as 100 Regent Street comprised the reconfiguring of the basement, ground and first floor retail areas from one large unit into three small retail units, and changing the second floor from retail to office accommodation.
The three retail units have been provided as shell installations with the requisite incoming services.
The second floor change to offices is based on the same approach as the upper floor refurbishment, providing a mechanical heating/cooling and ventilation solution within a raised floor, and suspended linear LED luminaires. This design makes the most of the floor to ceiling height, and allows the exposed ceiling irregular down stand beam arrangement to complement the space without imposing uneven suspended ceiling lines.
The office scheme will achieve a BREEAM 2014 rating of Very Good, and EPC rating of B for the office and retail space respectively.
