What will our public domain look like in 2050

Our main urban public spaces were designed at a time when our urban population was very small. Our georgian squares and green spaces are a great inheritance for both current and future generations. However many unforseen difficulties have arisen as we transport vaste volumes of peoples and goods, and live in higher densities in these spaces. What will the ratio of playgrounds to children be in 2050 ? How far will they have to walk to their nearest ground ? Where will new green spaces come from ? Which streets will have been pedestrianised ? How will the Phoenix Park have changed ? What will Dartmouth Square be ? Where are the docklands residential green spaces ?

Give us your thoughts any will do ........
