Ex mples of such non-residenti l uses could e
schools, l rge superm rkets, c r p rks, he lth
f cilities, sporting f cilities or employment

The study suggests th t the sc le nd complexity
of the development proposed y this typology
requires highly specific m sterpl nning nd ur n
design solutions. A design-led ppro ch would

Whilst sm ller-sc le he lth or educ tion l

likely th t the more complex ex mples of this
