Kellstone, Aire Park

Designed by Cartwright Pickard and owned by international real estate organisation Vastint, Kellstone is a new commercial building at Aire Park, Vastint UK’s mixed-use development on Leeds South Bank. The building provides 75,000 sq ft of Grade A office accommodation across six floors, alongside ground-floor space suitable for retail, food and beverage, and leisure uses.

Kellstone’s distinctive bull-nose frontage creates a prominent architectural presence, while its interiors combine spacious, column-free floorplates with abundant natural light, contemporary concrete finishes and vibrant forest-green tiling.

The building forms part of Aire Park’s wider 24-acre masterplan, a major regeneration project being delivered by Vastint UK. Once complete, the development will provide 1,350 new homes, 1 million sq ft of office, retail, leisure and commercial space, centred around eight acres of new public parkland.

Sustainability is embedded throughout the Aire Park masterplan and has been a key consideration in the design and delivery of Kellstone. The building has achieved BREEAM Excellent, EPC A and WiredScore Platinum certifications and is also targeting WELL Platinum, reflecting Vastint UK’s wider approach to creating high-quality, sustainable places for the long term.

The completion of the Kellstone building marks a significant milestone for the wider Aire Park project. The iconic building is ready for businesses to lease the space and fit out the 6 floors, bringing new employee communities to the area.

The overall regeneration project is well on the way to providing a complete work-life space for Leeds’ residents and commuters. The rich biodiversity, combined with modern industrial amenities, will help foster community and connection, clearly experienced by the Tate team throughout this seamless project.
