The housing estate proposed by the NSE is of high density. At least 30 dwellings to the hectare, out of character with adjoining dwellings.  They are also suggesting 9 blocks of 3-storey flats, subsidised and sheltered accommodation, none of which currently exist in the area. The NSE point out in their Leaflet #2 that government policy requires that all new developments to be of at least that density. So the NSE can't be held accountable, then. The amount of so-called "affordable housing" and "key worker" housing will be in accordance with Chiltern District Council's guidelines.  Once again, nothing to do with the NSE.

Meanwhile, the proposed internal site redevelopment by the NSE is not constrained by these mandates. No, in fact the NSE plan to retain a pleasant low-density open-plan layout for their site.  sense are sure it will be very nice too - a credit to all the architects and planners involved.

The net result of the NSE's plans (if allowed to proceed) will be 218 homes in a high density configuration, plus a 70-bed nursing home, plus an 85-person sheltered accommodation unit. All this in the midst of:
  •  Existing mature residential housing (with which it wouldn't fit in),
  •  The NSE's open-plan estate (with which it wouldn't fit in) and
  •  Greenfield Green Belt land on two sides (with which it definitely wouldn't fit in).

sense respectfully suggest that the NSE should be looking at the sensitive enhancement of their property, not exploiting it in a sensational and unsympathetic manner.
