The government is facing renewed pressure to invest in more homes for older people.
According to research commissioned by the National Housing Federation (NHF), carried out by YouGov, 52 per cent of homeowners aged over 55 would need to either adapt their current home or move if they develop mobility problems or care needs in later life.
This means that approximately 7.6 million people could have to stay in hospital until suitable housing arrangements are made.
The NHF has therefore urged the government to invest in "building the right homes for our future older population now".
David Orr, chief executive of the body, warned that if this does not happen, the impact on the NHS further down the line "could be catastrophic".
Just 24 per cent of homeowners aged 55 or over believe their current property would be fit for purpose if they developed mobility problems or care needs in future years.
Mr Orr argued that everyone deserves to live in a well-designed property that promotes good health and insisted that tackling this problem would "solve the care crisis and relieve pressure in the NHS".
He urged all political parties to commit to ending the housing crisis within a generation, with their solution involving a suitable provision of housing and care options for Britain's ageing population.
Estimates from the NHF suggest that in the housing association sector alone, more than 100,000 extra homes for senior citizens will be required over the next 15 years.
Mr Orr noted that housing associations have already started developing well-designed homes for older people that are "self-contained houses and apartments with built-in care services available when needed. However, he said they need assistance from the government "to do so much more".
Charlotte Cook, who is a Partner in our Social Housing Team commented "The impact of an ageing population on housing requirements needs consideration from all sides - as our population ages the needs of all residents must be taken into consideration when considering what housing we need and indeed where."
