Brief

The clients wanted to create extra en-suite bedrooms to the rear of the property and convert the existing garage, in this B listed property in Edinburgh.

The solution was to use the oval form of the existing staircase in the main house and sink the proposals into garden to form sunken courtyards facing curved waterfalls and steps.

The new roof forms a celtic knotwork garden inspired by the 16th century garden of the old town.

The design has been granted planning permission.
