Awgrymwyd mewn ymchwil yn 2015 y gellir adeiladu tua 7,600 o gartrefi ar oddeutu 400 o safleoedd ledled Cymru lle mae gwaith ar stop am resymau sy’n amrywio o waith cyn datblygu, hyfywedd economaidd, i heriau o ran sicrhau cyllid fforddiadwy. Gelwir y safleoedd hyn yn safleoedd segur, ac mae’r rhan fwyaf o’r rhain yn addas i’w datblygu gan y sector Busnesau Bach a Chanolig. Gellir datgloi’r safleoedd hyn drwy fuddsoddi a rhoi cefnogaeth gynnar, megis ar gyfer gwaith paratoi, gwella seilwaith neu helpu gyda llif arian.
Research in 2015 suggested there were potentially 7,600 homes on nearly 400 sites across Wales, where progression has been halted for a wide range of reasons, from pre development works and economic viability, to challenges in securing affordable funding. These are known as stalled sites, most of which are suitable for the SME sector to develop. Stalled sites could be unlocked through investment and support at an early stage, such as groundwork, infrastructure improvement or simply assisting with cash flow.
