West Bar is a major mixed-use scheme being developed by Urbo (West Bar Ltd) and funded by Legal & General. It comprises of Residential, Office, Commercial and Car Parking uses located to the North of Sheffield City Centre, at the the heart of the West Bar neighbourhood. 5plus has acted as masterplanner and architect for the development since early 2011 successfully securing outline planning consent in February 2017 and has subsequently been commissioned to deliver the first Grade A office building within the masterplan.

No.1 West Bar Square comprises approximately 100,000 sqft NIA of Grade A office, together with ground floor retail/leisure units. All of the commercial buildings around the square are conceived as a family each of which is embedded in Sheffield and the sites specific industrial past. The buildings work as a collective but also as individual buildings with those addressing Bridge Street being of a raw materiality whereas those fronting Corporation Street more of a polished and fabricated steel product.

No.1 West Bar Square sits at the end of the spectrum and is the building that is most connected to the new commercial style of the city. Its character depicts the more polished, refined end of the metalwork production cycle and is the gateway signature building to the square in both form and style.

A key principle of re-development has been the requirement to tackle climate change, in particular Environment Agency flood requirements with respect to site levels and existing structures. Design work has focussed on the recycling of demolition material to create the new site profile as part of the new sub-base and formation levels for the new buildings. A SUDS drainage and landscape strategy has also been adopted that extends the existing “grey to green” public realm from West Bar through the site in a series of raingardens and landscape attenuation features so the site acts as a better neighbour to existing adjacent sites.

All new buildings, including the initial Build to Rent (BTR) and No. 1 West Bar Square planning applications, will be low energy and low carbon in operation. Specifically all buildings avoid fossil fuels in respect of their energy source and each adopts a fabric first approach. No. 1 West Bar Square will achieve a 35% improvement on current Part L and have an EPC rating of A and BREEAM ENE 01 Score of 0.45 (Excellent). Beyond the fabric first approach to energy demand the residual requirements are reduced further through the provision of a PV array and air sourced heat pump (for domestic hot water) to meet the Sheffield City Council requirements for a minimum of 10% renewables.

The strategy of non-fossil fuel use, combined with a fabric first approach allows demand from the grid to be minimised and that demand to be met wholly through renewable tariffs and resulting in no local carbon emissions.

A Narrative for West Bar Square
Contextual and historical analysis of the area established a concept whereby West Bar Square should be seen as a family of buildings all of which are embedded in Sheffield and the site specific industrial past. The buildings respect and respond to this context with a confident re-interpretation of this industrial past in a new contemporary manner.

A tripartite arrangement of Top, Middle and Bottom is enshrined within the elevation and building design. The bottom of the building is conceived as a generous set back colonnade with GRC clad circular columns creating a strong base.
