Why it was refused

  1. The proposed side and rear extensions, by reason of their scale, siting and design, would be a visually incongruous addition to the street-scene. The single storey side extension is considered to be poor design which would unbalance the semi-detached pair of dwellings and result in an unduly tall and bulky addition to the host dwelling in a visually prominent location. Given the above, overall the proposed development, by reason of its siting, design, scale and mass is considered to result in incongruous and visually obtrusive additions to the dwellinghouse, to the detriment of the character and appearance of the area and the host dwelling. Thus, the proposal conflicts with the NPPF 2024, Policies CS22 of the Hertsmere Core Strategy 2013, Policies 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.
