SCULPTURAL STAIRCASES, DELIVERED SUSTAINABLY
PRECISION PRECAST FOR EXCEPTIONAL HOMES
For architects designing exceptional homes, the staircase is often more than a functional element- it is a defining architectural feature. Sweeping curves, helical forms and monolithic structures demand precision, consistency and a level of craftsmanship that traditional in-situ methods can struggle to achieve.
At Kallisto, part of Milbank Concrete Products, we work alongside architects and developers to bring these ambitious designs to life through bespoke precast concrete staircases- combining sculptural freedom with engineered accuracy.
Manufactured in a controlled factory environment, each staircase is produced as a single precast unit and delivered to site ready for installation. This approach not only ensures exceptional quality and finish, but also significantly reduces on-site labour, programme time and associated disruption. Installation can be completed in a fraction of the time- usually within a day- compared to traditional methods, helping projects stay on track without compromising on design intent.
Alongside performance and aesthetics, sustainability is central to our approach. Through continuous innovation in concrete mix design, we have achieved cement reductions of up to 21.5 %, alongside overall CO 2 savings of up to 33 % on complete precast products. These improvements support architects working towards the Future Homes Standard and broader net zero targets.
Our manufacturing processes are powered by renewable energy, including on-site solar generation,

while HVO fuel is used across deliveries- reducing emissions by up to 98 % compared to traditional diesel. Combined with ongoing reductions in energy usage and investment in low-impact materials, Kallisto offers a solution aligned with the environmental ambitions of modern construction.
For interior designers and developers, the result is a staircase that arrives installation-ready, providing a refined, structurally sound base for high-end finishes- from stone and marble to bespoke balustrades.
By bringing together design flexibility, programme certainty and measurable sustainability benefits, Kallisto enables architects to deliver homes that are as responsible as they are remarkable.
