Practice Areas

Harriet’s practice covers planning, environmental, local government, and related property law. She has over 20 years’ experience acting for developers, public authorities, individuals, and interest groups, in a wide range of cases within these fields.

Recent work: Harriet has successfully promoted two CPOs of London housing estates to deliver beneficial regeneration; resisted a planning injunction which risked closure of a school; defended a misfeasance in public office claim over the exercise of planning enforcement powers; and represented CPRW in its challenge to the Welsh Ministers’ approval of a windfarm which caused substantial harm to the setting of three scheduled ancient monuments.

Harriet represented the planning authority for the former North Wales Hospital at a series of inquiries and court appearances into contentious urgent works notices, the subsequent compulsory purchase order, and the related planning process. She is now advising on compensation.

Current work also includes planning appeals for housing development; promoting a major economic and related waste management use in the green belt; and the judicial review of a planning consent for hydrocarbon drilling.


Called in 1992.
