@keithalexander I think the problems start when you insulate under the suspended floor. There isn't a correct answer as to membrane or not. The temperature differentials will be reversed in summer and winter. For me the answer was to take out the floor and lay insulated slab with ufh. Lovely!
@EmilyKerr36 Check out Hills Rd Cambridge, bike paths go behind bus stops (bus stop bypass), albeit with regular buses. @hopsncheese is the guy who made it happen.
@olivercoppard@Psychosplodge Anecdotally, this is correct. My partner is now only doing 25% of the journeys in her van that she used to. She has switched many to cycle or walk.
