Frequently asked questions

When will the proposed development begin?

Should the application be approved, construction work on the new homes would begin from 2024. The new homes would be built in phases over several years, into the 2030s. A number of early-phase new homes will be delivered alongside quarry operation, with the remainder delivered once quarrying draws to a close. The aim is to have about 150 new homes built by end of 2027.

How many houses will be developed and when?

If approved, up to 800 new homes and up to 150 new specialist homes for older people would be built at Sevenoaks Quarry. The new homes would comprise market housing of different sizes, affordable homes, including to rent and shared ownerships, and first homes aimed at those wanting to get on the housing ladder.

Is there a need for these houses?

Yes. Sevenoaks has an urgent need to build a diverse range of sustainable, high-quality housing for families, first time buyers and older people, including care homes. Provision of this housing forms a central part of the proposals for Sevenoaks Quarry, alongside improvements to roads, cycling, pedestrian and public transport, a new primary school, and valuable outdoor community leisure space.

What type of homes will be built, and will locals be prioritised to buy them?

A range of housing will be developed, focusing on high-quality, sustainable homes for families, first homes and specialist accommodation for older people, and extra care homes. The affordable housing will include homes to rent and shared ownership homes, some of which can be prioritised for local people and key workers.

What proportion of the proposed homes would be affordable?

The exact proportion of affordable homes is not yet fixed but will be determined once the planning application is submitted and all development and infrastructure costs are known.

What will the houses look like? Will they be sensitive to the area's local materials and architecture?

The application is in outline form at present, which means the details of the buildings are not yet known. The details of the character and design of the home will be developed, should the proposal be approved. Tarmac is committed ensuring any proposals brought forward later can achieve high quality and sensitive design, reflecting local policies and guidance and being sensitive to local context, styles and materials.

Who would build these homes? Will Tarmac be involved, or will the land be sold to a developer if permission is granted?

Tarmac would stay involved to ensure the site is prepared and can be developed but then separate house builder/s would construct the new homes

Will new infrastructure be created to support the homes – ie transport, community, schools or leisure?

Yes. The development would support improvements to cycle and pedestrian routes and create outdoor leisure space for the whole community to enjoy. A new lake will be accessible for water sports, such as kayaking, paddle boarding and wild swimming, as well provide a setting for parkland with walking and running trails, picnic areas and play spaces. We would also seek to renovate the locally listed former Oast House for community, heritage and leisure uses and an existing barn for community uses. Land will also be set aside for a new primary school.

Have you assessed the infrastructure that this development will require? How will you ensure that the necessary doctors, dentists, social/elderly care, hospitals, care homes etc. are built to support the new population?

Tarmac is in discussions with different social infrastructure providers, for example Kent County Council on schools and the NHS on health. Where there is an identified infrastructure need as a result of development, new facilities will be provided on-site, or money made available to improve off-site facilities. In Sevenoaks, the District Council charges developers through the Community Infrastructure Levy (CIL) and money collected is used to improve infrastructure.

Will any commercial developments, shops, and office spaces be included?

The development would create spaces for local shops, cafés and other services, adjoining a mixed-use lakeside pavilion. This could also include space for a nursery/creche and a healthcare facility. Discussions are on-going with the local primary health care providers on healthcare and what could be achieved through the development.

How will you ensure that sustainability/green energy provisions such as electric charging points and renewable energy are embedded in the proposed development and housing?

The application is in outline form, but a sustainability document will be submitted with the formal application, setting out how development can assist in tackling and mitigating climate change. For example, through the management of energy, water and waste. Planning conditions can be attached to the outline permission requiring further information to be submitted at each detailed phase.

How will you ensure that sustainable transport options are central to the proposed development?

The proposed sustainable urban development would be an opportunity to support further improvements to cycle and pedestrian routes and extend key bus services through the site. A new east-west cycle and pedestrian route through the site will connect Bat & Ball Road to Childsbridge Lane. An off-road cycle lane is proposed next to Childsbridge Lane and an on-road cycle lane on Bat & Ball to connect to Bat & Ball railway station.

Have any assessments been carried out at the site to look at the impact on noise, dust, traffic or ecology?

Preliminary assessments have helped informed the proposals to-date, but more detailed assessments are ongoing as part of a formal Environmental Impact Assessment and will be set out in an Environmental Statement to be submitted with the planning application.

This development would create additional traffic. How will the current issues on local roads - especially at Bat & Ball junction - be mitigated and alleviated?

The proposed development would be an opportunity to support further improvements to cycling, pedestrian and public transport in Sevenoaks, encouraging traffic off the roads. This could include enhanced or new pedestrian and cycle routes, as well as extending key bus services through the site. We have also worked with the Town, District and County Councils to agree a scheme for improving Bat & Ball Junction.

How would any development work alongside an active quarry? Will the quarry operations come to an end sooner that currently planned, or would the two exist alongside each other?

A number of early-phase new homes will be delivered alongside quarry operation, with the remainder delivered once quarrying draws to a close.

When will quarry operations end?

Under the current planning permission, minerals operations and related uses at Sevenoaks Quarry are due to cease in 2030.

Will this affect the quarry restoration plans?

The site is being worked and restored progressively, but all mineral operations at the site are due to cease in 2030, after which time the rest of site would be restored. These proposals offer an alternative future, combining some of the previous restoration plans with new development and a leisure and recreation focus

Will any local jobs be created during the development phase

Jobs will be created through the construction of the scheme and through new on site uses employing people, such as the school, local shops or services and leisure facilities.

Previous FAQs

What is currently happening at the Quarry?

Sevenoaks Quarry has been around for over 120 years and is one of the largest sand quarries in the region. The Quarry produces high quality aggregates which are used in concrete, construction, and landscaping, and are used in construction and infrastructure projects of all sizes, both locally and across the wider London and South East area. Operations at the quarry were given planning permission in 2010 and the Quarry operates under the provisions and conditions of this permission, with operations due to cease in 2030, after which the site would be restored.

What is proposed for the Quarry?

Sevenoaks Quarry is being proposed as the potential location for a sustainable urban extension for North Sevenoaks. Its setting within Sevenoaks, along with its size, current industrial usage, and outstanding transport links, make it an ideal site for consideration to contribute to the future of the town. If successful, the plans would see the quarry gradually transformed, over the coming years, into a location for housing, along with community and leisure facilities.

Tarmac is working to prepare an outline planning application, which sets out broad principles for development rather than detailed development proposals, for submission to Sevenoaks District Council for its consideration in the coming weeks. If approved, further detailed applications will be made before construction begins, providing people with the opportunity to input and comment.

What will be delivered to benefit existing and new residents?

Alongside sustainable, high-quality homes, the development will provide recreation facilities, including outdoor leisure space and the use of the lake for water sports. We will also seek to provide improved pedestrian and cycle links for this part of north Sevenoaks, including the creation of new formal and informal parkland for mountain biking, relaxation, sport and walking.

The development will also provide a site for a new primary school, and will seek to renovate the locally listed former Oast House for community, heritage and/or leisure uses.

What will happen to the quarrying operations?

A limited number of new homes will be delivered alongside the quarrying operations. To enable this, some of the existing quarrying equipment will be relocated to another part of the site, further away from existing homes. The remainder of the homes will be delivered once the quarrying operations are completed.

How will the local road network be affected?

We are carrying out detailed assessments of the anticipated impacts of the development, and at this early stage we believe that highway safety and capacity improvements will be required at Bat & Ball Junction, alongside other works to enhance pedestrian and cycling connectivity. Issues currently under consideration with Kent County Council (as the Local Highway Authority) include provision of cycle routes across the development site, improvements to the route to Kemsing (including options for improvements at the Childsbridge Lane railway bridge) and to the west towards Otford Road.

Our technical assessments will look at the impacts of the Sevenoaks Quarry development in the context of other planned or recently completed developments in the area to ensure that studies are thorough. The technical work and any necessary improvements are being discussed with Kent County Council and further detail will be shared as the work progresses with an update provided at our next consultation event in October.

How will local wildlife be affected?

The site is currently managed and restored under measures that were approved as part of Sevenoaks Quarry’s exiting planning permission. This includes the creation of wildlife habitats at the north of the site, close to the railway line. One of the habitats which has already been created is for Great Crested Newts, which is protected by a newt-fence and is located to the north-east of the site. These wildlife habitats will remain as part of the development proposals.

Ecology surveys are currently ongoing on the development, to establish the wildlife that is currently present and how best to protect and relocate this wildlife. The development proposals will include a substantial amount of new habitat creation, including shallow margins to the lake which will support wildlife already at the site, and encourage new species. As our proposals develop, any impacts that are identified will be mitigated, where possible.

How will flooding be managed?

The site falls with Environment Agency Flood Risk Zone 1 (lowest probability of flooding) but it is still important to assess flood risk and manage drainage in a sustainable way. A flood risk assessment and a surface water drainage strategy, including measures such as Sustainable Drainage Systems, will be submitted with the planning application.

How will local footpaths be affected?

All the connections which are provided by existing footpaths will be retained, although some may need to be redirected slightly to accommodate the development proposed. New footpaths will be created to allow greater access to this area of north Sevenoaks, both northwards and east-west.

When will this happen?

We are aiming to submit an outline planning application to Sevenoaks District Council for its consideration in the coming weeks. Sevenoaks District Council will then consider the planning application, and this is likely to be heard in the second half of 2022. If the outline planning application is approved, further detailed planning applications will be made before construction work begins.
