Why it was refused
- The cumulative effect of the roof construction and materials, fenestration proportions, glazing ratio, exposed oak framing and the scale of the associated covered terrace would relate poorly with the character of the host dwelling. The proposal fails to preserve the significance of the heritage asset resulting in less than substantial harm it its significance. This harm is not considered to be outweighed by any substantial public benefit. The proposal is poor design. The proposal fails to comply with the Planning (Listed Buildings and Conservation Areas) Act 1990, Policies HOU11, DES4, GBR2, HA1 and HA7 of the East Herts District Plan 2018 and the NPPF.
From the council's decision notice.
