The site on Rochester Row is a 1980s five-storey concrete-framed red-brick block, which runs along Rochester Row between Willow Place and Stillington Street in Westminster. The building contains a mix of uses including; B1 office, C3 residential and D1 conference space. Each use is accessed via a dedicated core. The building has substantial roof-top features, including dormers, plant enclosures and lift over-runs.
Rochester Row contains a mix of buildings ranging in height from 3 storeys above ground to 8 storeys above ground. The existing building on the site is predominately 4/5 storeys above ground, however there is a large expanse of M+E plant equipment housed at roof level therefore the mass of the building can be viewed as 6 storeys above ground. The proposed roof top extension will not extend in height above this existing roof top mass, however it will unify the numerous elements of existing roof top mass into one cohesive element
Proposals to enhance the existing façade are driven by the existing structural grid as we understand it. The proposal is to retain all existing columns and use the fenestration between the columns as an opportunity for enhancements.
Across 1st to 3rd floor the existing elevation consists of a series of symmetrical bays and recessed areas which each contain 4 windows. Our intention is to modify the window openings to create 2 floor to ceiling windows, where there are currently 4. The proposed windows have reconstituted Portland stone reveals to lift their appearance. This strategy is then repeated across the entirety of the office façade. At ground floor level, the existing brick columns would be clad in reconstituted Portland stone and the tinted windows are replaced.
