Two-storey side extension at 9 The Crescent, Croxley Green, Rickmansworth
Summary of planning committee decision
Decided by Three Rivers Planning Committee on 27 May 2026.
What was proposed
The application sought permission for a two-storey side extension, loft conversion with roof alterations, a rear dormer and rooflights.
“To the front of the dwelling is an of hardstanding and to the rear is an amenity garden predominantly laid as lawn. The adjoining neighbour at No. 10 is also a two-storey semi-detached dwelling, this neighbour benefits from an existing single storey side extension. The neighbour to the north is No. 8, also a two-storey semi-detached dwelling, this neighbour benefits from a single storey side and rear extension and a detached outbuilding.”
“The proposal includes a loft conversion to the main dwelling, facilitated by a hip to gable extension, rear dormer window and a front rooflight. The dormer would have a total depth of approximately 3.5m and a width of approximately 5.4m. the dormer would have a flat roof with a total height of approximately 2.5m. Two windows are proposed within the rear elevation of the dormer. One rooflight is proposed within the front roofslope of the dwelling.”
Officer report
What consultees and neighbours said
The parish council objected, while residents raised concerns about privacy, overlooking, overbearing development, loss of light, appearance, parking and ongoing works.
“No. 10 has a separate planning application for a loft conversion and extension. When considered cumulatively, these developments would exacerbate the issues of overlooking and loss of privacy due to the increased number of windows. • Intrusiveness and visibility of the extension / overbearing nature. • Scale, bulk and siting of the proposed building not in keeping with the prevailing pattern of development in Cherry Croft. • Material reduction in natural light.”
“Two new windows at top of building and two additional windows on side elevation would directly overlook property, garden and bedrooms. • Due to height, depth and proximity to the boundary extension would be overbearing and visually intrusive. Sense of enclosure. Significant reduction in outlook. • Loss of privacy and light. Adversely affect views from property which is a Conservation Area. • Concerns that work continues regardless of application.”
