I roto i te hanganga whare noho, ko te nuinga o te hanganga raima e whakamahi ana i te pūnaha wai o nāianei. Ahakoa kua pakari te tikanga, he nui hoki te whakapaunga pūngao, he nui te parahanga me te iti o te hangarau. I roto i te "ōhanga waro iti", "hanga matomato" e puta ake ana ngā ariā pēnei i te aratohu, te huarahi whakahou i te hanganga whare noho, te whakatairanga i te ahumahi whare, kua noho te whanaketanga o ngā whare kua oti te hanga hei ia o te whanaketanga whare o tō tātou whenua. E ai ki ngā wheako, ki te whakataurite ki te tikanga hanga raima tuku iho, ka penapena wai te whare kua oti te hanga 80%, ka penapena rauemi neke atu i te 20%, ka whakaiti i te para hanga 80%, ka penapena pūngao whānui 70%, ka whakaiti i ngā utu tiaki 95%. I taua wā anō, ka taea te whakaiti i te papa hanga hei whakapai ake i te whai huatanga o te whakamahinga whenua.
Ngā whakaritenga mahi o te piripiri hiri mō te whare kua oti te hanga
Ko te piri tetahi o ngā āhuatanga tino nui o te hiri. Pērā anō hoki mō ngā rauemi turanga e whakamahia ana i roto i ngā whare kua oti te hanga. I tēnei wā, ko te nuinga o ngā pereti PC e whakamahia ana i te mākete he mea hanga ki te raima, nō reira he pai te piri ki te papa raima mō ngā hononga. Mō ngā rauemi raima, he uaua te whakatutuki i te piri noa o te hiri ki te mata, nā te mea: (1) he momo rauemi pūwero te raima, he koretake te tohatoha o te rahi o te kōhao, ā, kāore e pai mō te piri o te hiri; Kawakore (2) ko te raima tonu, inā koa i roto i te rauemi turanga he waikura, ka heke tetahi wāhanga o ngā matū kawakore ki te hononga hiri me te raima, ka pā ki te piri; (3) ko te wahi papa PC i te mutunga o te hanga o mua o te awheawhe, kia tukuna ai ka whakamahia te tuku pokepokea ai, ā, ko tetahi wāhanga o te kaihoko tuku e toe ana ki te mata o te wahi papa PC, ka uaua hoki te piri o te hiri ki te piri.
