Home / Case Studies / Royal Hospital Chelsea Carriageway & Drainage
The Royal Hospital Chelsea is a retirement and nursing home for 300 British soldiers. The South Grounds of the hospital not only provide a tranquil sanctuary for the Chelsea Pensioners, but host the prestigious Chelsea Flower Show. The show attracts more than 157,000 visitors every May. By 2014, there were two issues affecting use and access across the site; the existing asphalt was well worn and ageing, and an inadequate drainage system was causing continual flooding issues.


The Royal Hospital Chelsea grounds is a unique, central London site with an unusual demand on its infrastructure. It is dormant for most of the year with a few small private functions, until it hosts the Chelsea Flower Show, where 800 people spend 33 days building 20 show gardens. During this time, many heavy construction vehicles and up 400 tonnes of materials are dropped off. The Royal Hospital Chelsea wanted a durable carriageway and modern drainage system solution to last for years to come.
Marlborough were challenged with the construction taking place on a conservation area with many 300 year old protected trees, this meant it took materials 2-3 hours to get on-site.

“Marlborough attracts people who take care and have pride in their work. Several gangs of Operatives worked tirelessly for 6 months to reconstruct drainage networks, lay more than 3km of high quality bespoke granite kerbs and granite channels blocks to ensure positive drainage. The technical compliance, attention to detail and level of quality finish along the entire carriageway was exceptional.”
Mark Chiverrell, Technical Director Project Centre
Marlborough has 25 years’ experience of building carriageways, whilst overcoming on-site operational issues of large drainage projects. Which put them in a strong position. Marlborough’s Operatives had experience of operating recycling machines and hand laying ornamental granite kerbs, whilst their teams of Drainage Specialists could lay new drainage and modify existing areas.
