Kindness, Courtesy and Honesty

Thomas’s College is a new secondary school in Richmond Upon Thames for pupils aged 11 to 18. The school makes use of an existing Grade II listed Methodist training college, which first opening in 1842. Most recently the building was the American University in London. The school opened in September 2025, building to a capacity of up to 630 pupils and boarding accommodation for up to 58 pupils.

Mezzanine floors were added in the 1990s which cut the ground floor rooms in half, these were removed to restore the rooms to their former glory, opening up the space to allow the full height windows onto the garden to be appreciated. Breathing life into a building which has been neglected for years not only breathes new life into forgotten structures but also creates vibrant, resource-efficient, and inclusive learning environment.

Helen Whateley

Associate

Having attended a lecture by one of our Directors, Helen asked to visit the office to find out more about us.  She made an amazing impression and was offered a job after spending the day with us.  Her many gifts include an incisive mind and a persuasive (see above) and tenacious nature, qualities which are invaluable in so many of our projects.

One of our sportier members of staff, Helen enjoys skiing, tennis and the terrifying game of lacrosse.  As well as being a ski-instructor in Canada, she was Lacrosse Captain at Bath and a Lacrosse Counsellor at Tripp Lake Camp, Maine USA – the latter job title supplying the proof, if proof were needed, that lacrosse is not a sport to be undertaken lightly.
