Ibex House granted planning permission 14.12.22

The City of London Corporation’s planning committee has voted unanimously to approve proposals for the renewal and extension of the Grade II-listed Ibex House, located on the Minories.

Completed in 1935, Ibex House is a rare survivor of the fashionable ‘Streamline Modern’ movement, designed with striking horizontal lines and curved corners.

Working with our client, Henderson Park and Dukelease Properties, AHMM will return this iconic building to ‘best-in-class’ office provision, with a sensitive and discreet multi-layered approach, including a pair of refined single storey pavilions at ground, and another at roof level. The refurbishment will provide increased access to the building on three sides, with a new community space at ground floor.

The proposals have sustainability at the centre of the design approach, seeking to minimise operational and embodied carbon emissions through reusing existing fabric, re-introducing natural ventilation, substantially improving energy performance with high performance glazing and insulation, and moving away from gas to become an all-electric building. The development will achieve a significant reduction in operational carbon emissions, meeting the GLA’s Net Zero target, and providing bike parking to London Plan standards for new buildings.

Terraces have been incorporated to support the wellbeing of occupiers. Planting is integrated to sunken lightwells and roofs of the street-level pavilions, adding a degree of softness to the street scene and creating a green corridor with Portsoken Street Garden to the south, connecting to the World Heritage Site of the Tower of London beyond.
