ISG has been appointed by Legal & General Investment Management (LGIM) Real Assets for the £40m redevelopment of its Tempo office building in Maidenhead, UK.

The redevelopment project will transform the 112,000ft2 former office to a Cat A standard and will feature a two-storey extension to create another 21,500ft2 to the current building.

As per the terms, the scope of works includes the complete strip out of the current four-storey building to develop a sustainable office while keeping the occupier’s journey experience as the key aspect.

Providing flexible workspace, the occupants will stand to benefit from creative and outdoor areas with internal atriums and the addition of three rooftop pavilions and roof terraces that will create a total 11,000ft2 of biodiverse space.

Expected to become one of the greenest buildings in the Thames Valley, Project Tempo will focus on retain and reuse principles over a complete demolition and new-build approach.

The project will preserve most of the current stone exterior while giving the building’s appearance a new glazing façade.

Leveraging the Design for Performance approach, the project is targeting BREEAM ‘Excellent’ upon its completion, and seeking to achieve Net Zero Carbon in operation, with a total building energy consumption of 130kWh/sqm(GIA)/yr.

Its roof will house low energy technology including over 5,000ft2 of rooftop solar panels and air source heat pump technology to achieve an expected 39% reduction in the building’s carbon emissions.

Located on a 1.4-acre site adjacent to the train station, its location further fosters sustainable transportation options, with 18 electric car charging spaces and secure storage for 153 cycles.

ISG Construction business regional director Richard Skone said: “We’re excited to be working with LGIM Real Assets to realise the transformation of this existing office building into a state-of-the-art and sustainable workplace of the future. Project Tempo will demonstrate the best-in-class workspace and amenities that can be delivered through a retrofit approach to existing buildings, repurposing and enhancing what is there to minimise embodied carbon and maximise ongoing operational energy efficiency for its occupants.

“Situated in the heart of Maidenhead, this development further supports the region’s growth and helps it work towards a sustainable future. Being delivered by ISG Construction South’s Workplace team, the project exemplifies the quality of building and high levels of ESG credentials that we are committed to delivering for our clients along the M4 corridor in the London Homes Counties, Thames Valley and Bristol regions.”

Last week, ISG acquired a majority stake in modular specialist ESS Group, a modern methods of construction (MMC) contractor.

ESS has over 280 employees and has four offices and three manufacturing facilities across the UK and Ireland.
