Why it was refused

  1. The proposed development, due to its siting, design, scale and mass is considered to result in incongruous and disproportionate additions to the dwellinghouse. The two storey side extension/rear extension would create a terracing effect and a loss of side garden space which would not reflect the pattern of development in the area. The extensions would also be visually dominant to onlookers at Strafford gate, to the detriment of the character and appearance of the area. Thus, it would fail to comply with the NPPF 2024, Policy CS22 of the Hertsmere Core Strategy 2013, Policy SADM30 of the Site Allocations and Development Management Policies Plan 2016 and Hertsmere's Planning and Design Guide Part E 2006.

From the council's decision notice.
