As a landlord on Dartmouth Road since 1986, with several shops and flats, I have learned to take a balanced view on everything and, whilst I have a shop and entrances to flats even on that pathway, the fact that the nursery will be bringing lots of people to that part of the shopping area will be a big positive - especially as Fairway House, back in the day, employed dozens of people as did L&Q housing association in offices in Kingswear House (opposite), all of whom have been a loss to local eateries, hair salons and other shops.
So I say bring on everyone working at and bringing their children (on foot) to the new nursery!
By the way, I lived opposite a primary school for 8 years and I found that the sound of children playing out is one of the nicest ānuisanceā noises that there are.
