- CASE STUDIES
Bonhams is a fabulously idiosyncratic 1930s building, situated on prestigious New Bond Street, in West London. Viewings and auction sales take place throughout the year and it is here that buyers come from around the globe to find antiques and fine art of the highest quality.
The building is Art Deco in style, listed and within a Conservation Area. Architects Lifschutz Davidson & Sandilands led a £30million restoration project and sensitivity was key. The work included replacing the original steel windows on the front elevation facing Woodstock Street and Blenheim Street.
Clement W20 steel windows were chosen to match the design of the existing windows. The new windows were fitted with toughened, laminated glass and silicone fronted using dark bronze silicone (to replicate the early putty fronting).
A feature of the front façade is the set of fifteen curved on plan windows. Clement made templates so as to replicate exactly these fine windows.
All pivots, handle back plates and peg stays were polyester powder coated in RAL 8019 to complement the finish of the frames.
