St James’s Market Phase 2
St James’s Market Phase 2 is the “pioneer” related to the Design for Performance initiative and NABERS UK rating.

Located in the heart of Slough, the office building at 25 Windsor Road has been transformed.
The Client’s desire to improve the floor plate and create sub-tenancy flexibility drove the design to enhance the atrium and rationalise the cores to deliver improved net to gross efficiency.
The development has added a new floor with west facing terrace, together with a modern reception, so that more than 108,000ft² of office space is now provided over six floors wrapped around the central atrium.
The building uses a reverse cycle variable refrigerant flow (VRF) heat pump system to provide the office area heating and cooling. The efficiencies thus provided, along with ventilation heat recovery, LED lighting and sophisticated lighting controls and the building envelope thermal performance, have all enabled the building to achieve a Very Good BREEAM rating and an A rated EPC.

St James’s Market Phase 2 is the “pioneer” related to the Design for Performance initiative and NABERS UK rating.

Sustainability is incredibly important for the Client and as such the building is targeting BREEAM ‘Outstanding’, WELL ‘enabled’ Gold, alongside WiredScore Platinum. In addition, the Design for Performance approach is being adopted in order to minimise operational energy and hence carbon emissions.

The project also involved the refurbishment of the reception space and improvement of the cycle store entrance and wayfinding at basement level.

The 47,900ft² area of The Smithson building in Farringdon was refurbished to high quality office accommodation, for which Watkins Payne supplied building services engineering, vertical transportation engineering and energy consultancy to achieve an EPC B rating. The refurbished area is spread across basement and ground floor.

Multistory (formerly 2 Colmore Square and Cannon House) is setting the new benchwork for Sustainability, targeting WiredScore Platinum, Fitwel 2 star and Energy Performance Certificate (EPC) of ‘B’.

Building 600 located at Aztec West Business park in Bristol has been refurbished to offer 12,500ft² of high quality office accommodation, for which Watkins Payne supplied building services engineering, vertical transportation engineering, BREEAM duties and energy consultancy to achieve an BREEAM ‘Excellent’ and EPC B rating.
