The human version (we wrote this, not the council)This section explains what the Local Plan is and how it was prepared. The Local Plan is the council's main planning document, setting the strategy for homes, jobs and infrastructure in Three Rivers up to 2041. It must follow national planning policy and, once adopted, replaces the Core Strategy (2011), the Development Management Policies document (2013) and the Site Allocations document (2014). Work began in 2017 with several rounds of public consultation, backed by technical studies. The plan comes in two parts: Part I contains planning policies and Part II sets out site allocations.
Abbots Langley
11 sections of the plan, in document order.
The human version (we wrote this, not the council)This section explains the district's housing need and sets out the housing allocations policy. The plan runs from 2026 to 2041 and uses the Government's standard method, which gives a need of 832 homes a year and a target of 12,480 homes. After counting existing planning permissions and an allowance for windfall sites, 10,312 homes must come from allocated sites. The policy safeguards allocated sites for housing, expects development broadly in line with each site's stated capacity, and only allows earlier release of sites if the five-year housing land supply falls short.
The human version (we wrote this, not the council)This section sets out the site allocations for Abbots Langley and Leavesden. Eleven housing sites are allocated, references H1 to H11, with a combined indicative capacity of around 550 homes. They range from small garage courts of five or six homes to larger sites such as land adjacent to Fraser Crescent and Woodside Road, with 249 homes, and land at Mansion House Equestrian Centre, with 98. Each site table sets out size, phasing, Green Belt status and requirements covering matters such as access, heritage, flooding and trees.
The human version (we wrote this, not the council)This section describes the district and the issues the plan must tackle. Three Rivers covers about 88 square kilometres on the edge of London, with around 93,800 residents in 2021, projected to reach 98,919 by 2041 alongside a fast-growing over-65 population. It is among the least deprived areas in England, though pockets of deprivation exist, notably in South Oxhey. House prices averaged £594,000 in October 2025, making affordable housing a pressing need. Around 76% of the district is Green Belt, car dependency is high, and the council declared a climate emergency in 2019.
The human version (we wrote this, not the council)This section sets out the vision for Three Rivers as a desirable, prosperous district with sustainable settlements, a resilient economy and a high quality environment moving towards zero carbon. It lists the strategic objectives needed to deliver this, including a range of new homes with priority for rented affordable and family-sized housing, matching new jobs to new homes at a 1:1 ratio, making best use of previously developed land, and integrating infrastructure and sustainable transport. Other objectives cover heritage, climate change, biodiversity, open space, the district's rivers, good design, an ageing population, health and safeguarding the Green Belt.
The human version (we wrote this, not the council)This policy supports business growth by promoting a range of employment sites and premises across the district. Within designated Employment Areas shown on the policies map, extra industrial floorspace and intensified office and industrial uses are supported, and non-employment uses are only allowed where they would not harm amenity or the area's role. Outside these areas, losing employment land to other uses requires evidence including 12 months of unsuccessful marketing at a realistic price and no reasonable prospect of continued employment use. Creative industries and expansion of Leavesden Studios are supported.
The human version (we wrote this, not the council)This policy keeps Rickmansworth town centre and the district centres of South Oxhey, Chorleywood and Abbots Langley as the focus for shops, leisure and other town centre uses. Ground floors in primary shopping areas must keep active frontages that support the centre's vitality, while homes above shops are supported in principle. Local centres should meet day-to-day shopping needs. A retail impact assessment is only needed for schemes of more than 2,500 square metres of new retail floorspace outside the defined retail hierarchy, and shop fronts should suit the character of the area.
The human version (we wrote this, not the council)This policy governs the design and layout of residential development, requiring all schemes, including extensions, to meet the Design Criteria in Appendix 1. Development must not harm an area's character through tandem or backland building, poor access, excessive traffic or layouts out of keeping with plot sizes and street patterns. Tall buildings, meaning four or more storeys, over 12 metres, or substantially taller than neighbours, will be refused unless strict criteria are met. Converting a house into flats normally needs three or more bedrooms, and all homes must meet or exceed national internal space standards.
The human version (we wrote this, not the council)This policy protects the district's heritage, including 352 listed buildings, 22 Conservation Areas, Scheduled Monuments, registered parks and gardens, and locally important buildings. Applications affecting a designated heritage asset must include a Heritage Statement explaining the asset's significance and the proposal's impact. Substantial harm to or loss of listed buildings and other designated assets will be refused unless substantial public benefits outweigh the harm. In Conservation Areas, development must preserve or enhance character and appearance, with strict tests for demolition, and reuse of historic buildings to help tackle climate change is supported where significance is not harmed.
The human version (we wrote this, not the council)This section sets out the retail hierarchy and centre allocations. Rickmansworth Town Centre is the principal shopping and service centre, serving the whole district. South Oxhey, Abbots Langley and Chorleywood are district centres, while Croxley Green (Watford Road and New Road) and Mill End (Money Hill Parade) are local centres, with smaller parades serving day-to-day needs. New retail development will be directed to the primary shopping areas of the town and district centres first. The boundaries of these centres are set out in the allocations.
The human version (we wrote this, not the council)This section sets out the education allocations. A new secondary school site is allocated at Carpenders Park Farm, Oxhey Lane (ED1), able to accommodate a school of up to 10 forms of entry serving Carpenders Park, South Oxhey, Eastbury and parts of neighbouring boroughs. Land including and adjoining The Reach Free School (ED2) is allocated for a new secondary school or a four form entry expansion, and a primary school site at Woodside Road, Abbots Langley (ED3) is carried over from 2014. Identified school sites will be safeguarded for educational use.
