A group of 15 walkers from the Magor-based business scaled Pen Y Fan, Skirrid and then Sugar Loaf in aid of Birchgrove Comprehensive School, in the Vale of Swansea.
Their efforts have so far raised around three quarters of their £5,000 target, to be used towards materials for the DIY SOS-style project at the school.
The school was nominated for the fundraiser by Edenstone’s build director Mike Huddleston as his son Callum has autism and attends Birchgrove Comprehensive.
Mike said: “Callum thought it was awesome that the Edenstone team tackled the Three Welsh Peaks to help improve the outdoor space at his school. Luckily for the walkers, rain held off until their final descent. Now that the first stage of the challenge is complete, we’re working with the school to design the new garden. We hope to carry out the work during the summer holidays so that it’s in place for the new academic year.”
The plans for the outside space include an astro turf area, netball hoop, gazebo, covered seating area and low level climbing wall.
