For ten years, our client had struggled to gain planning consent for a home sited on a former tin mine with a unique set of constraints and challenges.

The exposed heathland plot contains the last remnants of a mining estate and forms part of the Cornish Mining World Heritage Site.

We were approached to re-assess the brief with a scholarly and sympathetic methodology, protecting the site’s heritage and delivering a 5-bedroom family home.

Understanding the complex limitations of the site required an 18-month process of collaboration with UNESCO and Cornwall Conservation and Planning departments.

Through rigorous research, we developed a coherent design strategy to restore and enhance the original mining structures and introduce contemporary elements without detracting from the site or wider landscape.

Removing unsympathetic alterations to the 17th century structures – including uPVC windows and concrete rendered local stone – we re-set the plan and reinstated slate rooflines.

The original Count House retains its prominence as the primary living space, with the former forge offering a series of quieter areas.

A lightweight loggia links the two heritage structures and leads to a new accommodation block embedded in the landscape to the rear.

Addressing the exposed location, we created a series of sheltered external spaces to be enjoyed throughout the year, as well as open terraces with incredible views along the coastline.

The previous treatment of the house and garden was progressively eroding the site’s historical significance, with a domesticity that neglected its mining heritage.

By actively embracing the site’s history, topography and natural landscape of scrub and heathland, we have created new purpose for the former industrial relics and established an innovative hidden home appropriate for its World Heritage Site setting.

"After such a long and delicate process, we are overjoyed that planning permission has finally been granted for this beautiful and sensitive site. It has been a joy to share the creative journey with ICA, and we can’t wait to see our dream for this cherished place come to life."
