Based just south of Cambridge, we have easy road and rail routes to the vibrant city centre. Being in this picturesque setting, we understand the importance of stopping and taking in some of the fresh air.

Making use of easy access to several acres of parkland and nearby rural areas, we have regular cycling and running groups going out during the lunch period and free fresh fruit delivered daily. Unwind and have fun with a calendar of social events, ranging from innovation talks, hiking trips, BBQs, curry nights, dedicated family events and much more.
