These are the questions we answer during the Research stage.

Answering them wil help us learn more about the Listed building outlines consideration, determine if a data standard is required and whether we know enough to move on to the next stage.

• Do we understand the lifecycle of a Listed building outlines?

  Yes

  • Document a stage of the high-level lifecycle of a Listed building outlines

• Do we understand how the data is created/produced?

  We have not explicitly asked Historic England how they produce their data yet. It is assumed based off of research and our initial conversation with them that they get the relevant point data from applications for listing, but it is yet unclear as to how they get their polygon data. When it comes to LPAs producing their Listed Building Polygon data individually, we expect that they will use: reference values from the Historic England dataset point data to identify the listed buildings which require polygons use OS basemap data from Mastermap to complete their polygons as accurately as possible.

• Where will or should the data be used?

  Knowing about a listed building will impact the information an applicant will need to provide to gain planning consent.

• What other planning considerations does it interact with?

  • Certificate of Immunity
  • Building Preservation Notice
  • Local plans - Listed buildings are referenced regularly in local plans (also under the guise of 'heritage assets'), so we think that this consideration feeds into the process of creating a local plan.

• Who are the statutory consultees for Listed building outlines?

• Other than the statutory consultees who are the primary users of Listed building outlines? How do we expect them to use Listed building outlines?

• What are the planning needs for this data?

• Who are the types of users who might benefit from having access to Listed building outlines data?

• What are some potential uses of Listed building outlines data?

• What's the value of adding Listed building outlines data to the platform?

• From what we have learnt so far are there any risks to making Listed building outlines data available?

  Historic England has said that if there is a listing that started before 4th April 2011, that this would not be polygonised. The risk of using Historic England’s data for polygons is that it will forever be incomplete and inconsistent.

  The issue is mainly in the curtilage and data accuracy. If the curtilage is incorrectly mapped and a decision is made based on this incorrect data, that becomes a criminal offence. If a curtilage is mapped beyond initial boundaries under the mindset of “better safe than sorry”, this will create much more work for LPAs as more applications for listed building consent will be “required” based on this data.

  To minimise this risk, curtilage would need to be properly defined, and then every listing in England would have to be independently assessed for accurate curtilage decisions before mapping. This is extremely costly and time consuming, in an environment where LPAs already struggle for resources. Historic England have also mentioned that they would struggle for resources to update the register in line with the amendment cases, which would also impact the SoS’ workload in confirming the new listing descriptions.

  The main question is: Is there a way we can work with Historic England and LPAs to reach a mutually agreeable decision?
