CSA is providing Quantity Surveying services for the transformation of a landmark office building in one of London’s most prestigious postcodes, at the heart of Knightsbridge. With planning consent secured, works commenced on site in Q1 2026. This exceptional development elevates an existing ground-floor entrance and three commercial floors, reimagining each level into boutique, premium-grade workspace. The scheme features a new lift installation, careful restoration of the external façade and the considered enhancement of usable roof space. The project showcases a rare opportunity to revitalise a building of character within a highly sought-after location, combining modern sustainability standards with the refinement of Knightsbridge’s historic architectural context. Positioned within the client’s wider strategy to unlock value from exclusive assets across Central London, CSA’s involvement includes commercial leadership, cost planning, procurement guidance and preparation of contract and tender documentation—ensuring a quality, risk-aware and value-conscious outcome for the client team.
