Denham Mount , Blacksmiths Lane, Tatling End, Buckinghamshire, UB9 4HW

Main issues, as the Inspector framed them

• Whether the proposal would be inappropriate development in the Green Belt having regard to the Framework and relevant development plan policies, including any relevant effects on the openness of the Green Belt
• Whether the proposal would preserve the Grade II listed buildings known as Denham Mount, Mount Cottage Denham Mount, Lodge Denham Mount and Entrance piers and gates at Denham Mount, and any of the features of special architectural or historic interest that they possess
• The effect of the proposal on the character of the site and surroundings
• The effect of the proposal on biodiversity of the area
• The effect of the proposal on transport networks
• The effect of the proposal on the living conditions of occupiers of nearby dwellings, with particular reference to noise and disturbance
• The effect of the proposal on the supply of housing in the area
• Whether the harm by reason of inappropriateness, and any other harm, would be clearly outweighed by other considerations, so as to amount to the very special circumstances required to justify the proposal

What decided it

The harm to the Green Belt by reason of inappropriateness and the substantial harm to the openness of the Green Belt, combined with considerable harm to the special interest of listed buildings and significant harm to biodiversity, were not clearly outweighed by other considerations and therefore very special circumstances did not exist to justify the development.

The substantial harm to the Green Belt and openness, considerable harm to heritage assets, and significant harm to biodiversity were not outweighed by the moderate weight given to economic benefits, tourism provision, and speculative concerns about the viability of residential use, resulting in dismissal of the appeal
