8 Turning now to the present case, it is necessary to compare the plans the subject of the existing appeal and the proposed new plans. The differences are summarised in paragraph 9 of the affidavit of Brian Krohn of 10 October 2006. The respondents emphasised the extent of the changes in the proposed plans. Working inland from the water, it was said first, that the amended plans no longer require the relocation of rock floaters (by which is meant some sandstone boulders from a partially collapsed cliff). Secondly, the seawall which appears in the existing plans now no longer appears. Thirdly, there is now proposed to be virtually no excavation, in contrast to the substantial excavation which appears in the existing plans. Fourthly, the stairs in the existing plans are depicted running across most of the site, whereas now they will be confined to a small part of the north-eastern boundary. Fifthly, the retaining walls have been deleted, at least on the water side of the swimming pool. Sixthly, the usable waterfront space has been removed in the proposed plans. Finally, the structured landscaping which appears in the existing plans, has been replaced by natural foreshore.
