The grain and scale expressed along the facades continue to form the soffits and the roof plant enclosures and guardrails. In this way, the rhythm of the buildings’ facades is extended like ‘ribbons’ up, along, over and down the extent of the building’s mass. On 2 London Wall Place they flow into the building to form the ribs of the reception ceiling, while on 1 London Wall Place they form the cantilevered soffit – some of the largest cantilevers in London – and their surfaces bounce light and reflections onto the walkways and landscaping below. The ‘Highwalk’ system, a reminder of the previous 1960s site, was a requirement of the planning consent. The walkway network now has a material palette of weathering steel and Iroko timber as a backdrop to the ever-changing gardens and green walls which seamlessly link the various levels. Thousands of plants, including strawberries, lavender and ivy, are distributed to suit various microclimates within the site, from the sun-blessed Salters’ ‘cascade’ to the sheltered water garden and ‘amphitheatre’ around the St Alphage remains.  These spaces will provide welcome respite for the 5,000 occupants of the new office buildings, retail customers, Barbican residents and future Crossrail commuters. THE MATERIALS – GRC AND CERAMIC – ARE DESIGNED TO NEVER NEED REPLACING AND THE WEATHERING STEEL WAS CHOSEN FOR THE BRIDGES SO THAT MINIMAL MAINTENANCE IS REQUIRED. The building is BREEAM ‘Excellent’ and designed flexibly to accommodate numerous tenancies throughout its lifespan, while the intent for the public realm is that it endures – as the Roman wall and St Alphage Church tower have – for as long as possible, as part of the historical urban fabric. There is a passive approach to energy in use, with a 50/50 solid-to-glazed ratio in the building facades, which are all heavily insulated, and with deep soffit areas to reduce solar gain. The air handling is mixed mode to allow both buildings to be naturally ventilated if desired. The materials – GRC and ceramic – are designed to never need replacing and the weathering steel was chosen for the bridges so that minimal maintenance is required.

Founded by Ken Shuttleworth in 2004, we’re an employee-owned firm pursuing a democratic design process. Today we have more than 150 people in London, Hong Kong and Sydney providing architecture, interior and urban design services from concept to completion. Since opening our doors, we’ve worked on more than 1,600 projects worldwide covering a wide range of sectors. We’ve delivered 79 built schemes from studios across 3 continents, including 50 buildings, 19 interiors and refurbishments, and 10 smaller design projects. We’ve also achieved more than 110 planning consents and realised over a dozen masterplans. www.makearchitects.com/projects/london-wall-place/
