Reimagining sustainable city-centre development
100 At the heart of Leeds’ thriving West End, 11 & 12 Wellington Place sets a new benchmark for sustainable commercial development. Comprising over 250,000 sq ft of premium office, leisure, and retail space, this landmark project is not only the most sustainable building in Yorkshire – it’s one of the most sustainable in the UK.
11 & 12 Wellington Place has achieved a NABERS five-star in-use rating, becoming the first UK building designed under the Design for Performance framework to receive this. The project exemplifies what’s possible when intelligent design, digital engineering, and a fabric-first approach come together. The two buildings, standing 10 and 11 storeys high and connected by a striking link bridge, form a key part of the wider Wellington Place masterplan, one of Europe’s most impressive business quarters.

Innovative engineering solutions
To meet the project’s ambitious sustainability goals, SES delivered a fully electric MEP solution. This included:
- Replacing gas-fired boilers with reversible air source heat pumps
- Installing air-cooled chillers to reduce operational carbon
- Integrating smart building controls for lighting and access systems
- Deploying a real-time energy management and metering system, feeding into a smart platform accessible via mobile app — giving tenants control over their environment
This approach not only eliminated fossil fuels but also enhanced energy efficiency and occupant comfort, contributing to a healthier, more resilient workplace.
Offsite and digital excellence
SES leveraged its award-winning offsite manufacturing capabilities to streamline delivery, reduce waste, and improve quality. Combined with our digital engineering expertise, this ensured precision, agility, and performance across every stage of the build.
