This scheme was delivered in two stages:
The first stage required Two Point Seven Facades to develop the design of the façade for the scheme. This included the production of various 3D visualisations using SolidWorks and Photoshop to capture the surrounding area, to ensure that the appearance of the car park was consistent with neighbouring buildings. Two Point Seven proposed a variety of options using this method, with different fixing centres and colours, so that the decision of how to proceed didn't require imagination as to the impact of small manipulations on fixings centres and colours.
The second stage included the procurement of 45 tonne of aluminium extrusion, the manufacture and installation of the façade. All carried out to the specification which was prepared by Two Point Seven prior to being engaged in the main contract. The extrusion was produced using 75% recycled aluminium, from post consumer aluminium scrap, drastically reducing the energy used during the production of the extrusion.
Building Description
The car park was built in 1972 as part of a regeneration process. It was utilised by the large premises above, hosting BT who managed Sheffield's phone network. The site is in a prominent location in Sheffield City Centre but consisted of vacant retail units due to the sorry state of the car park and offices above. The offices were refurbished in 2016 and is now used for student accommodation hosted by Vita Student. Two Point Sevens proposals enhanced the appearance of the car park as part of the overall improvement to the area. Transforming the car park into an iconic centrepiece for the entire scheme.
External Works
Brise Soleil - Two Point Seven used a system which closely resembles Brise Soleil, precisely arranged at varying angles to produce a wave effect. The wave feature façade includes a bespoke Aluminium two part extruded secret fix fin coated in Oxide Patina 2 from Two Point Seven COR-TEN Oxide Range. The fins are precisely arranged at angles from 0° to 6° with an increment of 0.5° to provide the 'wave' effect.
Goal Posts - Two Point Seven provided an aluminium façade to Charter Row around the shopfronts to facilitate the future installation of retail units. The cladding consisted of fabricated aluminium sheet metal, discreetly connected to support structure, carried by the car park.
Perforated Fencing - Part of the refurbishment required the enhancement of the service yards on Wellington Street and Rockingham Street. This included the installation of perforated fencing the full length of the service yards and an automated gate to allow access for staff, who can now securely park there vehicles.
Aluminium Capping - Aluminium capping was installed to the full length of the wall along Charter Row. The wall prevents a fall hazard to the ramp used by HSBC and the capping prevents the wall being used by Tony Hawks and Shaun White. The capping was manufactured using fabricated aluminium sheet.
Colour (Oxide Patina 2 from Two Point Seven Oxide Range) - The colour chosen was a COR-TEN look-a-like from our COR-TEN Oxide Range was produced specifically for this project and made available by Two Point Seven Facades.
