client: Private

value: Undisclosed

location: St Agnes, Cornwall


We were approached by a local couple who were keen to make the best use of an annexe building located in their garden in St Agnes on the north coast of Cornwall.


Previously used as a shed and wood store, the existing structure was constructed from local stone, slate, corrugated sheeting and blockwork. Working with a structural engineer we identified the elements that were still structurally sound and designed the accommodation around them. The modest timber frame extension houses a self contained flat for a dependent relative and is clad in a combination of local stone, locally sourced rough sawn larch cladding and Cornish slate. The low key design focuses on views into the neighbouring woodland.


The building was completed in June 2019.
