John Sisk & Son Partnership

Building sustainable futures together

John Sisk & Son and Quintain have forged a resilient partnership delivering scale, speed and consistency across one of Europe’s most complex regeneration projects.

Our partnership with John Sisk & Son on the NE02 and NE03 ('Solar' and 'Luna') developments reflects our commitment to building high‑performing, sustainable places through long‑term collaboration. From the outset, we aligned with Sisk on a shared ambition to reduce environmental impact, enhance community value and embed innovative construction practices into every stage of delivery. This strategic alignment enabled us to integrate forward‑thinking solutions that supported our wider sustainability objectives.

 

A key achievement was the introduction of a transportable, reusable containerised heat‑pump system that provided both heating and cooling on‑site. This approach significantly reduced operational energy demands, cutting usage by 70% compared with conventional systems. Additional measures, such as night‑time shutdowns of electricity and water, further strengthened resource efficiency and minimised unnecessary consumption. These innovations collectively reduced carbon emissions while demonstrating scalable models for low‑carbon site accommodation.

 

The transition to low‑carbon temporary facilities also delivered measurable performance outcomes: annual energy usage fell by 125.6 kWh per square metre, associated costs dropped by £85,000, and operational emissions decreased by 54,722 kg of CO₂. These outcomes show the impact of embedding sustainability into temporary as well as permanent on‑site infrastructure.

 

Our collaboration with Sisk also prioritised social value. Together we supported local employment, training and pathways into construction, including 15 apprentices, 835 hours of educational outreach and 169 roles for individuals from hard‑to‑reach groups. These commitments helped ensure that our developments generated inclusive economic benefits for the surrounding community.

“Partnerships are central to how we deliver sustainable, community‑focused places. By working with organisations who share our values and ambition, we can innovate faster, reduce impact more effectively and create developments that deliver long‑term social, environmental and economic value for the communities we serve.”

Designing Change Together

Partnerships Power Sustainable Progress

Quintain’s work with John Sisk & Son is more than a construction success story; it’s a testament to what’s possible when sustainability is embedded into every stage of development. As Quintain continues to shape urban spaces, partnerships like this will remain central to delivering places that are not only built to last but built to uplift.
