QODA were appointed to provide the MEP services design for the Conservatory Café at Cliveden. Designed in 1851 by Charles Barry, famous for designing the Palace of Westminster, the current building is the third house on the site, the previous two having burned down.  Cliveden has a colourful past, being the home of a Prince of Wales, two Dukes, and an Earl. In the 1920s and 1930s, it was the meeting place of the Cliveden Set: a group of political intellectuals and became famous for its lavish hospitality and glamorous guests, including Winston Churchill, George Bernard Shaw, Gandhi, and Henry Ford. Cliveden hit the headlines in 1963 when it became linked to the Profumo affair scandal. In 1966 the National Trust took over the management of the Estate, opening it to the public. QODA was appointed in 2019 to provide MEP design services for the Grade I listed Conservatory which houses a café. Due to the listed status of the building the services had to be carefully planned and coordinated, meaning various areas of joinery at low level and within the new roof structure was utilised.  Overheating was a real issue and a challenge to tackle. After producing a thermal comfort assessment, QODA introduced automatic opening roof lights, external louvres, and active cooling hidden within the low-level joinery. The lighting has been kept minimal and sympathetic to the listed beams with white linear fittings. The nature of the building also made smoke detection systems a challenge, as multiple smoke detectors across the building would have opposed the heritage of the building. To combat this, a one beam detector that covers the length of the building was used. The measures taken have not only improved customer comfort but have also seen enhancements for the staff.  A table tracking service that consists of receivers hidden under the tables and table trackers (provided with each order) lets the staff know which orders are for which table for ease of service. The project was completed in early summer 2022 and is now open to the public. It was awarded the RICS Award 2022 in the South East Heritage Category.
