A “Retain, Reuse and Retrofit” scheme for a postmodern building within the Bank Conservation Area.

The development retains the primary seven floors and replaces the 2 storey mansard roof with stepped and recessed upper storeys to create a new roof typology. These floors transition between the main body and roofscape, providing activated terraces and greening.

The development would maintain a large proportion of the existing building on Site, particularly its main frontage onto Lombard Street retaining and building upon its current character. The interventions and additions respond to the paired down Postmodern style of the host building and introduce a modern interpretation that sits comfortably alongside the original facades. The existing basement and lower ground floor are also retained and repurposed.

The character of the existing building is retained, and updated through improvements to window arrangements and a more activated ground floor that better relates to its street context.

The proportionality of the base, middle and top respond to the character of the conservation area. The concept is for the base to be formed by a double storey expression, the middle section expressed as paired window openings, and the uppermost storey with a simple rhythm of recessed panels.
