Summary of planning committee decision

Decided by Southend Planning Committee on 10 Dec 2025.

25/01314/FULHApproved

What was proposed

The application sought major roof changes, loft accommodation, side and rear extensions, a front extension, balconies and altered elevations.

“Planning permission is sought to remodel the existing dwelling by raising its roof ridge height, extending and altering its roof form with two dormers to the rear to form habitable accommodation in the loft space, erecting a single storey side extension, a part single/part two storey rear extension and a first floor front extension, installing balconies at first and second floor to the front and altering the existing dwelling’s elevations.”

“The existing dwelling’s roof ridge would be raised from some 9.1m to 9.4m high and its roof would be extended and altered from a front to back gabled roof with a side facing gable and a side facing hip, to form a crown roof with two gabled roof projections to the front. The proposed rear dormers would both have gabled roofs and would be up to some 1.7m deep, 3.3m wide and 1.9m high both with a window in the rear elevation.”

The site and surroundings

The site contains a large detached house in a residential area beside the estuary foreshore, within Flood Zones 2 and 3.

Officer report

Public comments

One neighbour supported the application but raised boundary and maintenance concerns, while the residents association objected to the loss of the house’s character.

“Supports the application but has concerns over the proximity of the proposal to neighbouring boundaries, potential encroachment of neighbouring boundaries by guttering and access for the future maintenance of external walls.”

“Chalkwell Ward Residents Association (CWRA) 4.2 CWRA have examined the plans for the above proposed development and wish to express disappointment at the plans, which involve substantial changes to the existing building, involving the proposed loss of so much of the character from the front of this handsome house.”

Officer report

The committee’s decision

Planning permission was granted subject to conditions controlling construction, materials, privacy, flood protection, roof details and balcony screening.

“The roof of the development hereby approved shall not be used as a balcony, roof garden or terrace or for any other purpose at any time without planning permission having been granted. The roof can however be used for the purposes of maintenance or to escape in the event of an emergency.”

“Notwithstanding the information submitted with the application and otherwise hereby approved, no development of the roof enlargement within the scheme hereby permitted shall take place unless and until full details of its crown roof have been submitted to and approved in writing by the Local Planning Authority under the terms of this condition.”
