Ngokuthuthuka okuqhubekayo kokuhlala emadolobheni, izindawo ezingaphandle eziluhlaza emadolobheni zidonse ukunakwa okwengeziwe. Kule nqubo, izihlahla zokwenziwa zangaphandle, njengenketho entsha eluhlaza, kancane kancane ziba yinto ebalulekile yokuklama kwendawo yasemadolobheni. Izihlahla zokwenziwa zangaphandle zengeza ubuhle obuluhlaza kanye nomkhathi wemvelo emadolobheni ngokubukeka kwawo okungokoqobo, ukumelana nesimo sezulu esinamandla kanye nepulasitiki ephezulu.
Okokuqala, ukubukeka kwangempela kwezihlahla zokwenziwa zangaphandle kungesinye sezizathu eziyinhloko zokuduma kwazo. Ngezinqubo ezithuthukisiwe zokukhiqiza nezinto zokwakha, izihlahla zokwenziwa zangaphandle zingabuyisela ngokunembile ukuma nokuthungwa kwezihlahla zangempela. Kungakhathaliseki ukuthi ukuthungwa kwe-trunk, umbala wamaqabunga noma ukuma komqhele, izihlahla zokwenziwa zangaphandle zingabukeka zicishe zifane nezihlahla zangempela. Lokhu kuvumela izindawo ezingaphandle njengezitaladi, izikwele namapaki edolobheni ukuthi zijabulele uhlaza oluluhlaza nobuhle bemvelo, zengeze ubungqabavu nokuthandeka kwedolobha.
Okwesibili, ukumelana nesimo sezulu kwezihlahla zokwenziwa zangaphandle kungesinye sezizathu zokuduma kwazo. Uma kuqhathaniswa nezihlahla zangempela, izihlahla zangaphandle zokwenziwa azikho ngaphansi kokuguguleka nokulimala okuvela endaweni yemvelo. Kungakhathaliseki ukuthi zichayeka emoyeni, emvuleni, elangeni noma esimweni sezulu esibandayo sasebusika, izihlahla zokwenziwa zangaphandle zigcina ukubonakala kwazo okugqamile kanye nesakhiwo esiqinile. Lokhu kuvumela abaphathi bedolobha kanye nezakhamizi ukuthi banciphise umsebenzi wokunakekela nokuphatha kuyilapho benciphisa ukusetshenziswa kwemithombo yemvelo.
Ngaphezu kwalokho, ipulasitiki ephezulu yezihlahla zangaphandle zokwenziwa nakho kungesinye sezizathu zokuduma kwazo. Kungakhathaliseki ukuthi indawo emaphakathi yedolobha noma indawo yomphakathi yezindawo ezingaphansi kwedolobha, izihlahla zokwenziwa zangaphandle zingenziwa ngokwezifiso futhi zenzelwe ukuhambisana nezimo nezidingo ezahlukene. Zingalungiswa ngokuma nosayizi ngokuya ngesitayela nezici zendawo, zenze umphumela wezwe oyingqayizivele futhi owenziwe ngezifiso. Ngesikhathi esifanayo, izihlahla zokwenziwa zangaphandle zingabuye zihlanganiswe nezinye izakhi zezwe, njengemibhede yezimbali, izici zamanzi, namatshe, ukudala indawo ecebile nehlukahlukene yasemadolobheni eluhlaza.
Ukwengeza, izihlahla zokwenziwa zangaphandle ziyasimama futhi aziyilungele imvelo. Njengoba izinto eziningi ezenziwe ngazo ziyizinto ezivuselelekayo noma ezihambisana nemvelo, izihlahla zokwenziwa zangaphandle zinciphisa ukusetshenziswa kwemithombo yemvelo kanye nomthelela omubi emvelweni. Ngesikhathi esifanayo, izihlahla zokwenziwa zangaphandle azidingi imithombo yemvelo njengenhlabathi, amanzi nokukhanya, ukunciphisa umonakalo endaweni yemvelo. Lokhu kwenza izihlahla zokwenziwa zangaphandle zibe yisinqumo esimeme sokutshala emadolobheni, ngokuhambisana nokuphishekela komphakathi wesimanje ukuvikelwa kwemvelo kanye nentuthuko esimeme.
Ukufingqa, izihlahla zokwenziwa zangaphandle, njengenketho entsha eluhlaza, zengeza ubuhle obuluhlaza kanye nomkhathi wemvelo emadolobheni ngokubukeka kwawo okwangempela, ukumelana nesimo sezulu esiqinile kanye nepulasitiki ephezulu. Baletha uhlaza oluluhlaza nobuhle bemvelo emadolobheni ngaphandle kokudinga ukunakekelwa nokuphathwa okuningi. Kukholakala ukuthi ngokuthuthuka okuqhubekayo kanye nokuqanjwa okusha kobuchwepheshe, izihlahla zokwenziwa zangaphandle zizodlala indima ebaluleke kakhulu ekutshalweni kwezindawo zasemadolobheni, zilethe indawo engcono nehlala kuyo izakhamuzi zasemadolobheni.
