Hardwick street involves the comprehensive refurbishment and extension of a former warehouse building in Clerkenwell, London.
Works to the ground floor include the repositioning of the main entrance door to improve its prominence. The refurbished reception features a new passenger lift, polished concrete floor, bespoke feature lighting, and a bespoke brass directory.

Across the first and second floors, the intention was to work with the existing structure of the building and reveal its original character; expressing the steel structure and brickwork walls. This sensitive approach to the aesthetic was associated with reflecting the local street scene and historic area. The third floor is a hybrid of old and new. Original brickwork, and clean plastered ceilings – this a result of concealing the structural strengthening for the new fourth floor.

On top of the original flat roof, a completely new floor has been constructed, providing a bright and open plan office space. The new fourth floor in place of the original flat roof adds 2,330 sq ft, bringing the building total up to 12,910 sq ft.

Schueco curtain walling to north and west facades provides the building with a landmark architectural feature. With a generous roof terrace that offers unique and special views over London. An array of photovoltaic panels on the flat roof and the incorporation of low energy lighting reduce carbon emissions. Areas of sedum roofing to the new terrace, providing a micro-habitat for birds and insects.

新楼层主要使用Schueco FW50+立面系统和ADS 65 HD玻璃门。玻璃立面的设置作为一种手段，将街道和周围保护区内新建建筑的可见度降到最低，同时又提供了美观的建筑形象，与周围区域融于一体。在设计过程中，建筑师愈发清晰地意识到项目需要使用玻璃立面和玻璃门相结合的玻璃结构体系，紧密地包裹和覆盖新加钢结构框架。Schueco“曲棍球棒”风格的内部竖框结构使这一体系成为可能。建筑安装的太阳能控制玻璃可以反射大部分太阳能，降低吸收太阳热量带来的影响——考虑到建筑大面积的使用玻璃，这一点显得尤为重要。
This new floor is predominantly constructed from the Schueco FW50+ façade system and ADS 65 HD glazed doors. The arrangement of glazing served as a device to minimise the visibility of the extension from the street and the surrounding Conservation Area but simultaneously to look beautiful for the users and to blend in with the surrounding area.During the design development, it became apparent that the project needed a glazing system that combined glazed façades and doors, that could seamlessly wrap up and over a new structural steel frame. The Schueco ‘hockey stick’ style internal mullions made this possible. Solar control glass was installed to limit the impact of solar gain, to reflect away a large degree of the sun’s heat – a crucial feature given the quantities of glass used.

Washroom areas are brought up to modern standards with superloo WCs and shower facilities. New signage and wayfinding throughout gives the building a clear identity.
The essence of the project is sustainability; the reuse of an existing building to suit a client’s needs, rather than demolition and reconstruction. Lytag lightweight concrete was used for the new concrete slabs. Lytag is a recycled lightweight aggregate that is a by-product from power station fly ash. Alongside this, there has been a wholesale replacement of all M&E services.The scheme met the occupiers needs in a number of ways. There is a high level of demand for exactly this type of space in this area; open plan, characterful offices flooded with natural light, plentiful bike storage, showers, and external space.
