More than £500 has been raised by estate agents in Rickmansworth to help a foodbank and the redecoration of a classroom.
Trend and Thomas raised the money last week by getting local children to paint and decorate a Wendy House.
Visitors were charged £1 to decorate their own brick.
The money raised will go to the Rickmansworth foodbank and Rickmansworth Park JMI School reception classroom rebuild
The classroom has been out of action since the roof fell down, and it is hoped that it will be rebuilt by September.
Belinda-Jane Guilfoyle, from the estate agents, said: "It was great fun, we had lots of local kids enjoying the fun and we are delighted to have made some money for two really worthwhile causes."
