Main issues, as the Inspector framed them

The effect of the proposed development on the character and appearance of the host dwelling, the surroundings of Marsden Green and the wider Welwyn Garden City Conservation Area

What decided it

The cumulative scale and disproportionate width of the side extension, combined with the rear extension, would overwhelm the modest scale of the original house and harm the character and appearance of the Conservation Area, with no sufficient public benefits to outweigh this harm.

Framework references: 212, 215, 139, 129

Plan policies cited: Policy SP15, Policy SADM15, Policy SP9

- Landscape and environment. Green belt, national parks and national landscapes, SSSIs, ancient woodland, SPA, SAC and Ramsar sites, nutrient catchments.
- Flooding. Flood zones 2 and 3, surface water, and both again with climate change.
- Transport. The 800 metre station catchment and service frequency, bus stops with their weekday frequency, the cycle network, and the Framework’s transport tests measured for the site.
