Mae pwyslais cryf ar ‘greu lleoedd’ o fewn y polisi newydd – sef dull o ddatblygu sy'n sicrhau bod gan gymunedau yr holl wasanaethau sydd eu hangen arnynt o fewn cyrraedd a bod datblygiadau yn rhai o'r radd flaenaf.  Cymru fydd yr unig wlad o fewn y DU a fydd yn mabwysiadu'r dull hwn o gynllunio.
The new policy has a firm focus on ‘placemaking’ – an approach to development which ensures communities have all the services they need within easy reach and development is of high quality. Wales will be the only country in the UK to take this approach to planning.
