Sustainable Heritage: A Cornish Barn's Evolution

PL13   |    Pioneering Off-Grid Living in a Historic Setting

The brief

We were presented with a curtilage-listed bank barn in a stunning location near Looe, Cornwall. The challenge was to create a sustainable three-bedroom family home while preserving and enhancing the building's historic significance.

Heritage considerations

The project required careful navigation of:

  • Preservation of historic fabric and character.
  • Enhancement of the Grade II listed farmhouse setting.
  • Compliance with listed building requirements.
  • Integration of modern living spaces.
  • Achievement of ambitious sustainability goals.


Design philosophy

Our solution embraced a dual approach:

  • Thoughtful adaptation of the original barn for private spaces.
  • Contemporary extension for family living.
  • Glazed link creating a clear distinction between old and new.
  • Strategic implementation of off-grid technologies.
  • Careful consideration of the historic farmstead context.


Crafted details

  • Traditional materials: unpainted oak joinery.
  • Local stone and lime mortar construction.
  • Agricultural heritage-inspired metal roofing.
  • Preserved architectural features.


Modern integration

  • Off-grid capabilities.
  • Carefully positioned solar PV installation.
  • Sympathetic contemporary extension.
  • Optimised spatial planning.


Conservation success

Our heritage expertise secured both planning and listed building consent, demonstrating:

  • Successful preservation of a heritage asset.
  • Integration of sustainable technologies.
  • Harmonious blend of historic and contemporary design.
  • Enhanced historic farmstead setting.


This project exemplifies BluePrint Architectural Workshop's commitment to creating sustainable futures for historic buildings, delivering homes that honour their heritage whilst embracing modern environmental standards.

What clients say

Customer review:

"BluePrint Architectural helped us right from the start in shaping our vision for the restoration and extension of the ancient barn. They successfully navigated us through conservation planning and building consent listing to obtain permission for a creative solution that not only met our brief but was also acceptable to the planners.


We have retained BluePrint to oversee the next stage of our build, and we look forward to seeing the new building emerge from the old. Paul and his team work with high quality, are responsive to our questions and requests and are able to provide creative solutions when required."
