Advantages of Precast Stairs:


Precast concrete stairs are cheaper than a stair cast insitu on site due to the efficiencies we have within a factory environment.   


A precast concrete stair can be installed in a day and often at the same time as the structural flooring. Insitu poured concrete stairs often take weeks to build, cast, strip and finish.   


Providing an immediate working platform a precast stair can be used as soon as it is installed. Insitu poured stairs will require alternative access routes to the upper floors while they are being built.   

Quality and waste 

Using a flexible steel formwork system enables the precast stairs to be made accurately and to a high quality. Precasting allows the repeated use of formwork whereas insitu concrete pouring results in the formwork being disposed of on each project.

Construction Benefits 

  • Fire Resistant  
  • In most cases eradicate in-situ concrete  
  • Speed of Installation, minimising time spent on site  
  • Health & Safety – In most cases, once installed acts as an immediate access route and can easily be installed with the addition of a temporary handrail

March 2019

Milbank are proud to introduce Kallisto Stairs – a new concept in the United Kingdom for precast concrete curved stair design.

Work has now completed at the St Helen’s School of Music in Northwood, Middlesex. The distinctive brick and terracotta-clad building houses classrooms, individual and group practice rooms, a music technology suite, recording studio and a dedicated performance space.

Working with IID Architects, Kallisto Stairs (the luxury precast concrete helical stair division of Milbank Concrete Products) provided a stunning precast concrete helical feature stair that can be seen through the glass entrance, stretching the height of the building over two floors.

Kallisto's Stairs Supply Denham Film Studio

September 2017

Denham Film Studio

The Denham Film Studios are a unique collection of 224 conversion and new build homes, including 154 one, two and three bedroom apartments and 70 four and five bedroom family townhouses.

Features within the new development will include a retained and restored cinema with bar and a community hall/fitness space. The new properties are designed around garden squares, landscaped grounds, rill water features, private gardens and protected woodland complete with parking and garaging.

The main Grade II listed building will be converted into 49 elegant apartments, around this will be two new green squares and communal gardens, bordered by three new four storey apartment buildings providing 105 new homes. Around the eastern side of the site there will be avenues of new three and four storey terraced housing, and to the northern section two and three storey detached townhouses; all overlooking communal landscaping and private gardens.

Under current plans the retained cinema – which was used to screen movies to Hollywood directors including Stanley Kubrick, Albert “Cubby” Broccoli and Steven Spielberg - will be refurbished and turned into a cinema theatre and club for residents; retaining an important link to the history of the site.

Kallisto's Role
Weston Homes, one of our top clients, approached us to investigate if we would be able to provide two precast concrete helical staircases at our factory in North Essex, incorporating 150mm wide by 900mm high concrete handrails to tie up with the art deco style balustrading to the circulation areas of their flagship development site in Denham.

Constructing these flights insitu would have proved to be challenging in terms of generating the flowing soffit and erecting the necessary formwork which would have needed to remain in place for at least 4 weeks after the second flight had been cast.

A staircase with a built in handrail of this size has to our knowledge never been made off-site in a factory environment and was a real technical challenge to not only structurally design but to also tie in with the buildings design. There were also restrictions on transport to site and how they would be lifted into position to consider due to the sheer size and weight of each individual flight.

Although immensely challenging we were completely satisfied with the final result and the effort by the whole Kallisto team certainly resulted in a well designed, manufactured and installed finish product.

The Developer
Over the last two decades, Weston Homes Plc has continually striven to produce innovative, high quality homes to appeal to purchasers from all walks of life. Their aims have remained constant; to match traditional skills to the very latest technologies in an on-going desire to produce homes to the best specification and standards possible.

Weston Homes prides itself on achieving the coveted What House National Building Developer of the year 2010 award, which is testament to their commitment and recognition that our quality is second to none in the country.

The variety of developments we have produced is impressive; from traditionally styled bricks and mortar houses and apartment blocks to contemporary ground-breaking designs in steel and glass, ranging from 20 units through to complexes with hundreds of homes.
