Angel Building

The scheme creates a high-quality public realm that integrates the development into the streetscape. Trees, hedges and clipped planting create a generous green transitional space that can be occupied between the repurposed building and street. The landscape creates a welcoming entrance to the building that reinforces the historic grain.

The public realm integrated the existing mature trees planted in the 1980 into the scheme, as key requirement of achieving planning in the conservation area. J&L Gibbons ensured that through close arboricultural attention, above and below ground, construction could be achieved through the trees without damage. New plane tree planting was incorporated between clumps of existing trees. The scheme demonstrates the effectiveness of a retrofit and how a close relationship of built and natural form can be achieved. This was immediately popular in terms of securing tenants, while contributing to the street and London’s urban forest.
