Overbearing planning is a term used to describe the impact a development will have on its surroundings, particularly a neighbouring property, in terms scale, massing and dominating effect. Overbearing planning is often a reason for rejection of planning applications since it is subjective and can also be overturned at appeal.

Whether a proposed building or extension is considered to be overbearing will be assessed on a case-by-case basis, taking into account several factors. Some of the reasons why a development might be deemed overbearing include:

• The physical ‘presence’ of a building.
• Its scale and mass.
• An oppressive feeling as a result of the development.
• An intrusive feeling as a result of the development.
