It would help if retirement communities offered a greater variety of properties. For many a small one bedroomed flat is sufficient, but others want more bedrooms, bigger living space, hobby space and so on and i cannot think of any good reason why developers cannot build such mixed developments.
The first retirement community was built by the Joseph Rowntree charity in York. A friend of mine lives there. She has a large and roomy 2 bed bungalow. Both bedrooms have ensuite and every thing is designed to be comfortable for wheel chair users, wide doors, big rooms, a huge living room. All the accommodation is on the ground floor. Along one wall of the living room is a straight staircase, carefully designed and sited to make it easy to fit a stair lift.
It goes up to a cavernous loft area, plastered, carpeted and with lots of roof lights.It is for whatever the owner wants.
My friend is a musician, who plays chamber music, and she uses it as a rehearsal space. Other residents use them for railway layouts, libraries, studios, someone has a fully equipped workshop up there.
Why are there not more developments like that?
