B40 Frameless balustrade; B30 Frame and Infill balustrade; B20 balustrade; B10 handrail
Taylor Wimpey's Paddington Exchange in London was designed by Powell Dobson Architects and Assael Architecture. It contains 150 apartments and has 3 towers which step up to a maximum height of 14 storeys. The development provides 1, 2, 3 and 4 bedrooms apartments, a combination of private and public amenity space, along with roof terraces and private balconies.
The building was designed to create maximum light. Powell Dobson commented on their vision for the balconies and terraces: “structural glass balustrades create glamorous appeal from the outside, while allowing uninterrupted views out to the London skyline.”
With the balustrade being an integral part of the architectural vision, this BIM Level 2 project presented a number of initial design challenges
Bouygues UK contracted BA Systems to deliver balustrading to the inset balconies, terraces and stair cores.
For the inset balconies and terraces, where glass balustrading was required B40 Frameless balustrading was proposed. Two fixing details were designed to accommodate varying upstand heights. On the terrace areas were the parapet wall provided a fixing surface, the boss fixing option was utilised. Where the fixing details had to be concealed beneath the finished floor level, BA Systems' design team developed a galvanised steel bracket to offset the ICE 1 channel from the upstand.
To complement the brick facade, a vertical bar balustrade was required for some inset balconies and BA Systems proposed the B30 Frame and Infill balustrade. In order to create a sturdy solution that met loading regulations, the company's design team developed 2 bespoke fixing options for the balustrade. In some areas there was only a 100mm-wide upstand to fix to, so a bespoke ‘stepped’ steel post was developed. In other areas, a bespoke steel plate was used to fix a B30 handrail through the brick slip facade into the steel windpost.
On the stair cores, the B20 balustrade with a satin stainless steel handrail and glass infill was complemented with 42mm-diameter stainless steel B10 handrail.
In order to protect the balustrades on site and ensure a quality finished product for hand over, BA Systems wrapped posts and handrails prior to delivery from its manufacturing facility.
