Why it was refused

The proposed replacement building, by virtue of its increased footprint, mass and bulk, would be materially larger than the one it replaces and would therefore not meet the exception set out in paragraph 154 d) of the NPPF (2024). Given the history of previous additions to the parent dwelling, the proposed outbuilding cannot be considered as a proportionate extension over and above the original building and would therefore not meet the exception set out in paragraph 154 (c) of the NPPF (2024). By virtue of its size, position and cumulative sprawl across the site, the proposal in both spatial and visual terms would result in harm to the openness of the Green Belt. No very special circumstance has been submitted to outweigh the harm identified by definition and other harm. Given that the works fail to accord with any of the exceptions for appropriate development in the Green Belt as set out in the NPPF, the works are unacceptable in principle and amount to inappropriate development in the Green Belt. The proposals therefore fail to comply with the National Planning Policy Framework (2024) and Policy CS5 of the Dacorum Borough Core Strategy (2013).

From the council's decision notice.
