- The dormer extension, though protruding 500mm above the ridge line, is visually acceptable because the property is stepped forward from the adjoining terrace and does not form a continuous ridge line.
- There is no convincing planning reason to require the omission of the bathroom in the gymnasium, provided the structures remain ancillary to the single dwelling unit.
