The facility is to be erected in woodland at Dumfries House near Cumnock in Ayrshire to help pupils to learn about the natural world.

The timber classroom is designed as a place for children to learn about the natural world and will host science, technology and engineering (Stem) workshops.

Charles’s representatives said he wanted children to be able to come to the estate to learn about industries such as aerospace, renewables and sustainability to help them find jobs in the future.

A design statement submitted by Prince Charles’s foundation said: “When it comes to specific themes of the Stem programme, there will be some potential advantages to the build and design of the outdoor classroom and education centre that could be advanced.

“Geometry and mathematics and how patterns appear in nature as well as design of buildings and structures is a key teaching theme within Stem.

“Using the structures as an opportunity to highlight strong shapes such as triangles, reflection and rotational symmetry, and patterns in the structure, will give really nice opportunities to teach and make comparisons between the natural and built environment.”

Charles has owned the Dumfries estate since sealing a £45 million deal to buy the property and its original furniture collection in 2007.

The 2,000-acre estate in which the house is situated is open to visitors and, in 2018, the prince was given permission to build a wedding venue on the site.
