Mostly, private housing developments are required to have some element of 'affordable' housing incorporated. That's not really 'public' housing.

Enabling Development
English Heritage’s Policy Statement and Practical Guide to Assessment: Enabling Development and the conservation of heritage assets has provided a standard approach to considering enabling development since its publication in June 2001. We have now decided to update this guidance in light of practical experience, changing legislation, some additional issues that have emerged, and a greater number of relevant reports and decisions by the Planning Inspectorate. The intent of the policy itself remains the same, but some changes of wording are proposed to clarify meaning and bring its presentation into line with the emerging English Heritage Principles, Policies and Guidance for the sustainable management of the historic environment.

http://www.english-heritage.org.uk/serv ... w=nav.8384In June 1999, English Heritage published a Policy Statement, Enabling development and the conservation of heritage assets, advocating a presumption against enabling development unless it meets specified criteria, the most important of which is that the benefits clearly outweigh the disbenefits. In June 2001, we republished the policy statement, supported by practical guidance to planning authorities on the assessment of applications – and so, of course, to owners and developers on what they should submit by way of justification.
The value of the first edition of this Guide was demonstrated by the speed with which it was taken up and applied by owners, developers, planning authorities, and the Planning Inspectorate. Since that time, our policy and guidance on enabling development has been set within the wider picture provided by our emerging Conservation Principles, Policies and Guidance for the sustainable management of the historic environment.
A key aim of this second edition has been to update references to legislation (particularly the change to Local Development Frameworks) case law and decisions on appeal or call-in. It now concentrates on those areas of practice which are particular to enabling development (and by extension other proposals where financial viability is a key issue), rather than common to most proposals affecting heritage assets. The publication of, particularly, Informed Conservation (2001) has made possible the omission of much general guidance in the previous edition.
We have taken the opportunity to revise or expand guidance on topics particularly associated with enabling development, including historic entities, farm buildings, levels of restoration, and taxation.
I hope that this edition will be even more helpful to practitioners than its predecessor.

On telly tonight is an update of
To the Manor Born. The house which featured as the Manor in the original series, Cricket St Thomas, is now a hotel - set amidst a tarmac car park. and a large extension. Many thought and still think this 'enabling' was a step too far.
