Two-storey house extensions at Linden Grove, Gussage St Michael
Summary of planning committee decision
Decided by Dorset Northern Area Planning Committee on 10 Feb 2026.
What was proposed
The application sought two-storey front and side extensions, a raised ridge height and a front porch.
“Description of development The proposal scheme seeks to erect a two-storey front extension and a further two-storey side extension, raise the ridge height and erect a front porch.”
Officer report
The site and surroundings
The dwelling is a detached brick house in the village, with private grounds, mature boundaries and varied neighbouring buildings within a National Landscape.
“Key planning issues Issue Conclusion Principle of development The principle of extending and altering a residential dwelling within a village location such as this is acceptable where it accords with wider material planning considerations. Scale, design, impact on character and appearance There is no demonstrable harm to the character and appearance of the area.”
“All buildings along the road are two or one and a half storeys in height and of traditional brick construction with occasional elements of render, timber cladding and hung tiles. With the exception of the Old Rectory site and adjacent woodland, all the land along Manor Road is occupied with low density dwellings.”
Officer report
Consultation responses
The parish council objected, while Dorset Wildlife Trust, the Ramblers Association, the rights of way officer and the ward member made no comments.
“Flood Risk Zone 3a Flood Risk Zone 3b (indicative) Risk of Surface Water Flooding Extent 1 in 1000 Surface water flooding - 1 in 100 year event plus 40% allowance 8.

DC - Rights of Way Officer – no comments received 4. Cranborne Chase Ward Member– no comments received 5.”
“The following comment was received as an additional response to the reconsultation: • The Planning Notice to be displayed issued 23 Oct by Dorset Council, not on website until dated 28 Oct when consultees written to. Therefore closing date on website states 11 Nov for comments BUT IS NOT 21 DAYS as required. Site Notice was displayed on 7 Nov at the property BUT no closing date written on it.”
Officer report
Other planning effects
The proposal was judged not to increase harm to the protected landscape or flood risk, while biodiversity measures were secured by condition.
“The addition of windows at first floor level on the rear elevation will not result in a demonstrable increase in existing levels of overlooking due to a combination of the set-back nature of the proposed side extension, existing boundary treatments along the western side of the site and the existence of an access driveway running along the western boundary creating a large area of separation between the proposed development site and neighbouring ‘The Walled Garden’ and ‘The…”
“Biodiversity - A Biodiversity Plan (BP) has been prepared for the site following ecology assessments where bat activity was found. The BP is supported by a certificate of approval from Natural England and secured by condition. Environmental implications There are no demonstrable environmental implications. 16.”
