I would suggest that would still not suffice, as the company knows that its prospective residents will still be able to see you/us if we accepted a move to the beach adjacent to the current location. They want you/us out of sight of the development which will mean invading the more popular public beach to the West, which I can't see PCC agreeing to.
The point is though, it's not up to QinetiQ (or any future owner of the site). Eastney Beach is a very popular naturist beach by long-standing tradition and they have to just accept that it will stay that way whether they like it or not. If the proposed residential development is ever built, any future residents will have to accept it too. There's no good reason for naturists to stop using the beach, so we're not going to.
I still say that if we do end up with flats there, the developers should wake up to the obvious, and market them as ideal new homes for naturists! Win-win situation - it would be the biggest naturist community in the UK. There must be *loads* of people who would just love to live somewhere in the UK that they could walk out of their flat and straight onto the beach without ever putting a stitch of clothing on. The grass areas between the blocks of flats would become nude sunbathing lawns. People would downsize and move here after their kids had left home, or retire here. QinetiQ need to stop causing trouble and have some imagination.
