What do you mean by 'feasible'?
Can it be done? Of course.
Is it at all likely? Not on your nelly.
is it possible?
100,000 homes per year?
of course it is, ONS stats show that for decades we used to build over 300,000 per year, all through the terrible bankrupt 1970's when we were 'broken'
where the Green Party would allow 100,000 homes per year to be built would be interesting, you will struggle to find 100 towns a year for 5 years to accept a 1,000 house developments in the existing confines of the town and I'm not sure the Greens will allow new towns to be built on newt occupied grasslands
so history says yes, easy, but practicality suggests it won't happen (imagine the amount of road it would commit the greens to building!)
