Family annexe at The Hawthorns, Burscough, Ormskirk

Summary of planning committee decision

Decided by West Lancashire Planning Committee on 23 Apr 2026.

2026/0080/FULApproved

What was proposed

The application sought to convert an existing garden building into an annexe for a family member, with living space, one bedroom and a shower room.

“Planning permission is sought for the conversion of an existing ancillary outbuilding to an ancillary annexe to accommodate a family member.”

“The annexe would include a kitchen / lounge, 1 bedroom and a shower room. The dimensions of the proposal building are as follows: Height – 4m Height of eaves – 2.1m Width – 6.9m Length – 11.7m Total footprint – 80.73m2.”

Officer report

The site and building

The site is an isolated two-storey home in open countryside, within the Green Belt, with a rear garden containing the existing brick outbuilding.

“The application site relates to a detached, two-storey dwellinghouse on Crabtree Lane, Burscough. The site is in a relatively isolated position, to the west of Burscough in the open countryside. There is a cobbled driveway to the north-east of the property and a large garden to the rear (north-west), which includes a brick outbuilding (the subject of this application). The site is located in the Green Belt but not in a conservation area.”

Officer report

Earlier permission

A 2024 certificate of lawfulness approved the detached outbuilding for use as a gym and games room.

“2024/0694/LDP - Certificate of lawfulness - Proposed detached outbuilding to house gym and games room. APPROVED.”

Officer report

What officers recommended

Officers recommended approval because the building’s use would remain ancillary, would not harm Green Belt openness or residential amenity, and would leave its exterior unchanged.

“The application site is in the Green Belt, wherein the NPPF guides that new development is inappropriate unless an exception applies. Paragraph 154 (h) iv. allows for: "the re-use of buildings provided that the buildings are of permanent and substantial construction." The outbuilding is considered to be of permanent and substantial construction.”

“Concerns have been raised about the impact on residential amenity as a result of the proposed annexe. The specific concerns relating to residential amenity focus on the more permanent use of the building as ancillary accommodation instead of the intermittent use as a home gym.”

Officer report

Consultation responses

Drainage and highways officers raised no objections, with drainage requesting a condition for separate foul and surface water drainage.

“Drainage – No objections raised. Requested a condition be included relating to the submission of a drainage plan showing separate foul and surface water drainage.”

“Lancashire County Council Highways – No objections raised.”

Officer report

Residents’ concerns

Two neighbours raised concerns about Green Belt impact, residential amenity and possible independent residential use, while the parish council objected over the Green Belt.

“Neighbour representations – Two neighbour representations received raising concerns relating to the impact on the Green Belt, impact on residential amenity and concerns relating to potential use as an independent residential unity.”

“Burscough Parish Council – Objected on grounds of impact on the Green Belt.”

Officer report

Conditions proposed

The report proposed conditions covering drainage and requiring the outbuilding to remain an annexe rather than a separate dwelling or business.

“3) No development shall take place until a detailed drainage strategy for the separate foul and surface water drainage of the development is, including any necessary infiltration measures, attenuation measures, use of rainwater harvesting system such as water butts, design calculations, permeable paving and phasing of delivery if applicable, has been approved in writing by the Local Planning Authority.”

“4) The outbuilding which is the subject of this application shall be occupied solely as an annexe to the property known as No. 59 Crabtree Lane, Burscough, and shall not be used as a self-contained dwelling, separate and apart from No. 59 Crabtree Lane or for use for business purposes, holiday letting or air bed and breakfast uses.”

Officer report

Committee decision

The committee granted permission, amended a condition to prevent separate sale, added restrictions on permitted development rights, and delegated final wording to the chairperson.

“B. That condition 4 be amended to prevent the property from being sold separately, and an additional condition be added to remove permitted development rights for outbuildings, extensions, and hardstanding.”

“C. That the final wording of the revised conditions be agreed in consultation with the Chairperson.”
