Supplementary Planning Guidance

What is Supplementary Planning Guidance?

Supplementary Planning Guidance (SPG) are documents produced by the Council to give guidance to the public, applicants and developers when making planning applications. SPG provides supplementary information in respect of the policies in the adopted Torfaen Local Development Plan. It is a means of setting out more detailed thematic or site specific guidance on how these policies will be applied in particular circumstances or areas. SPGs are one of the 'material considerations' taken into account when determining planning applications or appeals.

SPG can take the following forms:

  • Topical guidance such as shop front design or biodiversity
  • Site specific guidance such as development frameworks or development briefs; and
  • Numerical guidelines or thresholds which may change during the plan period, such as car parking standards, so as to avoid the current plan becoming too quickly outdated. This does not however include where these targets are key policy such as targets for future housing provision

Interactive mapping

To support some of our SPG documents, we have put together an interactive map: Torfaen County Borough Council - Local Plan: Masterplanning ( This is currently specifically relevant to the Green Infrastructure SPG adopted 27 Feb 2024, the Site Design, Masterplanning and Development Brief SPG adopted 28 Feb 2023 and the Sustainable Locations SPG adopted 13 June 2023.

Please click on the link to access a map of Torfaen with viewable layers of information (both constraints and opportunities) to help with your site analysis and design of your development site. A locality or site can be found by zooming to the right area or via the address search function. The different layers of information can be viewed individually or in combination as required by clicking to turn them on and off. The eye symbol identifies those that are visible. Any additional information available is accessed via the ‘i’. Distances and areas can be measured using the tool. There is a tutorial and help function within the software on the left hand side of the screen but if you have any issues or queries, please do not hesitate to contact us at

Please be advised that this information source represents the most up to date data that we have but should still be checked by any user to ensure its accuracy ‘on the ground’.

A Welsh language version of the mapping is available by clicking on the language button towards the bottom left corner of the screen.

Development Viability Model (DVM)

The Council has worked in partnership with other Councils across the region, alongside Town Planning and Development consultants Burrows-Hutchinson Ltd, to establish a viability assessment tool. The DVM has been created as a comprehensive, user-friendly model that can be used by site promoters and decision makers for the purpose of assessing the financial viability of a development proposal. To obtain a site-specific copy of the DVM, together with the user guide and videos, or to discuss any matters relating to the DVM, please contact us on

The fee charged will contribute towards the administrative and professional resources required within the Planning Department to provide the planning service.
