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.
The carbon neutral status was achieved by exemplary as-built air tightness facade solar and thermal performance significantly in excess of the Building Regulations requirements, highly energy efficient M&E systems, LED lighting and photovoltaic panel arrays on the roof of the warehouse.
The building services use a 4-pipe fan coil unit arrangement with various ventilation systems to suit the different use areas. Full building power back-up standby generation, UPS, security and access control and automatic blinds all formed part of the fit-out.
The 7,600ft² area of 7 Bermondsey Street near London Bridge Station was refurbished to high quality office accommodation, for which Watkins Payne supplied building services engineering and vertical transportation engineering. The refurbished area is spread across basement and ground floor.
The MEP services were all replaced with a focus on energy efficiency using air source heat pumps, LED lighting and natural ventilation where possible.
The development Pegasus Mayfair is targeting a B rated EPC, BREEAM ‘Outstanding’ and WELL ‘Gold’ and Watkins Payne is providing these services.
