"3.46 In that context and taking into account recent draft guidance, boroughs should set thresholds above which affordable housing requirements will apply at no greater than 15 units, and are encouraged to seek a lower threshold through the UDP process where this can be justified. Boroughs are encouraged to ensure that the affordable housing requirement applies to any site which has the capacity taking into account other policies of the plan to provide the minimum number of dwellings set in their threshold."
"H16 Where a development involves 15 or more dwellings, and taking into account paragraph 10 of Circular 6/98, the Council will ensure that 25% of the proposed provision is affordable."
"H14 All proposals for housing development will be considered in the context of the need for a variety of different types of accommodation, including housing for single people, large and small families, people with disabilities and people with other special needs. The Council will pay particular attention to those households who cannot afford to purchase or rent suitable homes on the open market and will seek the provision and retention of a proportion of new housing as affordable units. The Council will seek the maximum contribution that each proposal can reasonably make to meeting local housing needs, taking into account the quality of the site, size, location and other relevant land use criteria. H15 Unless unsuitable on the grounds set out in policy H14, all schemes should include a mix of accommodation, suitable for small households and for families."
"4.3.6... Land in Islington is extremely scarce and each site must to be used as efficiently as possible. For this reason, in accordance with advice contained in the government Circular 6/98, the Council has set a 'trigger level' of 15 or more units at which a proportion of affordable housing will be sought. As set out in policy H16 this proportion will normally be 25%. However, the Council will take account of the suitability of the site, the economics of provision and the need to achieve a successful housing development when considering the affordable housing element. In furthering the objectives of policies H14 - H16 the Council may request information from applicants to help it assess the contribution to meeting housing needs that a particular scheme may make."
"Boroughs should normally require affordable housing provision on a site which has a capacity to provide 10 or more homes, applying the density guidance set out in [the relevant policy of the plan]... Boroughs are encouraged to seek a lower threshold through the DPD process where this can be justified in accordance with Government guidance."
"6.53 We make another point here. New Policy 3A.8i as written is not absolute [that is the relevant policy I just referred to about the threshold of 10]. It contains the word 'normally' — something which is not normal these days in planning policy-making; this occasioned some discussion at the EiP and the view was expressed that it was justified in this case to make clear that the policy was not rigid. It also sits alongside Policy 3A.7 (unchanged) which refers to the need to apply policy flexibly, taking into account site costs, the availability of subsidy, and other factors. Paragraph 3.41 talks about viability and the individual circumstances of the site. It is important to read the policy in the context of these statements and other supporting paragraphs. 6.54 The context for the debate is that there is a clear shortage of affordable housing in London. The TCPA [whatever that is] pointed out to us that since 1979 London has lost more than 260,000 affordable homes through the Right to Buy scheme. Last year 6,037 new affordable houses were provided and 11,549 sold through Right to Buy... The LCF gave us powerful evidence of the level of housing enquiries at Citizens Advice Bureaux. Furthermore, Policy 3A.7 of the London Plan — that 50% of provision should be affordable — is not being met (we were told that the current figure is 32%). We received evidence about the difficulties which Londoners have in affording to buy housing and we have no doubt that this is a very serious problem."
"6.62. But we do accept that there may be special circumstances in some Boroughs which might mean that the London wide threshold was inappropriate; if arguments could be put for a higher or lower figure we would accept that as a result of the LDD process different outcomes might ensue. (The policy itself encourages Boroughs to go for lower thresholds where possible through DPDs. The Mayor comments on this issue in the last part of BN67). But we prefer to establish a policy, from which departures might be possible, rather than to establish no policy and to allow one to evolve."
"6.69 The Mayor produced some figures which showed that in those Boroughs which had already adopted a threshold of 10 there appeared to have been no such damaging effect... All but one of the eight Boroughs which had been operating it for some time had exceeded their housing targets, with an average 126% of target across the eight (compared with 119% in London as a whole). And as we have noted the policy is not in any event a rigid one and it sits alongside others which do require viability in individual cases to be taken into account."
"53. Further Alterations to the London Plan are in preparation, and following the Examination in Public the Panel has reported on these. The Panel came to the conclusions that a new policy should be included in the Plan setting out a threshold, but from which individual boroughs might make departures. They also came to the view that a threshold of 10 dwellings would be justified. The new Policy 3A.8i would state that Boroughs should normally require affordable housing provision on a site which has the capacity to provide 10 or more homes, and that they should be encouraged to seek a lower threshold."
"55. As it stands adopted national policy and policy for London sets a maximum threshold of 15 dwellings. However, there are indications that in London this may be reduced to 10. There must still be uncertainties about the policy that will eventually be adopted by the Council, but given the need to provide affordable housing in the Borough I have given some weight to the lower threshold in reaching my decision."
"57... In general, I consider this is a thoroughly considered scheme that makes efficient use of the site for the proposed uses. In those terms it would accord with the aims of UDP Policies Imp 6 & H15, which seek to make efficient use of sites and to ensure a mix of accommodation."
"58. Given the difficulties in achieving an acceptable scheme for this site, the constraints in terms of its physical nature and character, and concerns about density of development and amenity of nearby residents, I am not convinced that a significantly greater number of dwellings would be feasible."
"59. Furthermore, uncertainties remain about the setting of any new threshold for affordable housing provision at both regional and local level. The scheme falls considerably below the indicative threshold of 15 units recommended by PPS3, and below the maximum threshold of Policy 3A.8 of the adopted London Plan. In general, I am not convinced that the need for affordable housing is sufficient to outweigh the considerable advantages in terms of the quality of the scheme and its enhancement to the area. I conclude on the third main issue in Appeal B that the proposals make efficient use of the site, and in the present policy climate that there need be no provision of affordable housing."
"36. The reasons for a decision must be intelligible and they must be adequate. They must enable the reader to understand why the matter was decided as it was and what conclusions were reached on the 'principal important controversial issues', disclosing how any issue of law or fact was resolved. Reasons can be briefly stated, the degree of particularity required depending entirely on the nature of the issues falling for decision. The reasoning must not give rise to a substantial doubt as to whether the decision-maker erred in law, for example by misunderstanding some relevant policy or some other important matter or by failing to reach a rational decision on relevant grounds. But such adverse inference will not readily be drawn. The reasons need refer only to the main issues in the dispute, not to every material consideration. They should enable disappointed developers to assess their prospects of obtaining some alternative development permission, or, as the case may be, their unsuccessful opponents to understand how the policy or approach underlying the grant of permission may impact upon future such applications. Decision letters must be read in a straightforward manner, recognising that they are addressed to parties well aware of the issues involved and the arguments advanced. A reasons challenge will only succeed if the party aggrieved can satisfy the court that he has genuinely been substantially prejudiced by the failure to provide an adequately reasoned decision."
"(2) The developer will not normally be entitled to his costs unless he can show that there was likely to be a separate issue on which he was entitled to be heard, that is to say an issue not covered by counsel for the Secretary of State; or unless he has an interest which requires separate representation."
