Why it was refused
- The proposal by reason of the addition of a front porch would increase the domestication of the building, negatively affecting its traditional character and appearance. The increase in the ridge height would have a detrimental impact on the historic character of the curtilage listed building. Furthermore, the addition of a crown roofed dormer would result in an incongruous addition to the traditional form of the building resulting in a detrimental impact to the character of this curtilage listed building. Therefore the proposal would cause harm to the significance of the curtilage listed building, the setting of the listed building Port Hill House, and would be detrimental to the character and appearance of the Hertford Conservation Area, contrary to Policies HA1, HA4, HA7, DES4 and HOU11 of the East Herts District Plan 2018, the Bengeo Neighbourhood Plan, the statutory requirements of the Planning (Listed Buildings and Conservation Areas) Act 1990 and the NPPF.
From the council's decision notice.
