The final plans for the £36 million redevelopment of Nightingale's north London home, Hammerson House, reveal that capacity will increase by more than a third, from 85 to 120 residents. The original proposal was for a 102-resident capacity.

Nightingale Hammerson leaders said this week that the proposed model of care had been shaped by the new wings at the Nightingale home in Clapham.

Bedrooms will have optimum exposure to sunlight and sufficient space for visitors to sit, important for those who are bedridden. The rooms will be reached through social areas, furnished with memory objects.

On the upper floors, suitable for residents with lower levels of dependency, there will be a shared assisted kitchen space overlooking gardens.

Subject to planning permission from Barnet Council, building work will start in 2017 and take two years. Hammerson will be closed during the renovation with residents offered places at Nightingale or the charity's other home, Belmont Lodge in Bushey. They will also be given information about other care options.

The home will be closed for the two years of construction

Where possible, staff will be offered posts at the other homes.

Nightingale Hammerson chair Melvin Lawson said the redeveloped Hammerson would provide "a shining example of the highest standard of person-centred care".
