Uphahla,njengefacade yesihlanu yesakhiwo, ikakhulu ithwala imisebenzi yokungangeni manzi, ukuthintela ubushushu kunye nokukhanya kwelanga. Kwiminyaka yakutshanje, ngenxa yemfuno eyahlukileyo yeempawu zokwakha, uphahla lukwathathwa njengenxalenye ebalulekileyo yokumodela izakhiwo, ekufuneka iqwalaselwe kuyilo. Xa abathengi abaninzi beza kuthi ukuze bayile, bahlala bekufumanisa kunzima ukukhetha uphahla oluthe tyaba okanye uphahla oluthambekileyo. Eli nqaku liza kukwazisa kwaye lichaze ngokucacileyo ukufana kunye nomahluko phakathi kwezi zimbini, ukuze ube nokuqonda okusisiseko xa ukhetha.

Okokuqala, masithethe ngokuqheleka kophahla oluthe tyaba nophahla oluthambekileyo.
Zombini kufuneka zibe neempawu zokuthintela amanzi nobushushu, kwaye zombini zifuna umaleko ongangeni manzi kunye nomaleko ongangeni manzi. Akukho nto ithi ukusebenza kophahla oluthambekileyo kungcono kunophahla oluthe tyaba. Uphahla oluthambekileyo lusetyenziswa kwiindawo ezinemvula kuba lunethabathi yalo, okulula ukuyikhupha amanzi emvula eluphahleni. Nangona kunjalo, ngokwesakhiwo esingangeni manzi, uphahla oluthe tyaba kunye nophahla oluthambekileyo zifuna amaleya amabini angangeni manzi. Uphahla oluthe tyaba lunokuba yindibaniselwano yezinto ezibhityileyo ze-asphalt kunye nokwaleka okungangeni manzi. Ithayile yophahla oluthambekileyo ngokwayo lukhuselo olungangeni manzi, kwaye umaleko ongangeni manzi ubekwe ngaphantsi.
Ukusebenza kophahla olungangeni manzi kuxhomekeka kakhulu kwizinto ezingangeni manzi kunye nezakhiwo, ezingenanto yakwenza nokukhethwa kophahla oluthe tyaba kunye nophahla oluthambekileyo. Ungayicinga ngophahla oluthe tyaba njengedama elikhulu lokuqubha, kodwa injongo yale dama akukokugcina amanzi, kodwa kukuvumela amanzi aphume ngokukhawuleza kumbhobho ongaphantsi. Ngenxa yokuba ithambeka lincinci, amandla okukhupha amanzi ophahla oluthe tyaba awakhawulezi njengophahla oluthambekileyo. Ke ngoko, uphahla oluthe tyaba lusetyenziswa ngokubanzi kwiindawo ezinemvula encinci emantla.

Okwesibini, masithethe ngomahluko phakathi kwezi zimbini
Ngokwendlela yokwahlulahlula, uphahla oluthe tyaba kunye nophahla oluthambekileyo lungasetyenziswa ngeendlela ezahlukeneyo, kubandakanya uphahla lokungenisa umoya, uphahla lokugcina amanzi, uphahla lokutyala, njl. Ezi phahla zimiselwa ngokwengingqi kunye nemozulu yendlu. Umzekelo, uphahla lokungenisa umoya kunye nophahla lokugcina amanzi luya kukhethwa kwiindawo ezishushu. Olokuqala lulungele ukufudumeza umoya ngaphakathi kunye nokutshintshiselana kwamanzi, kwaye olokugqibela lunokudlala indima yokupholisa ngokwasemzimbeni. Ngenxa yeendawo ezahlukeneyo zokuthambekela, uphahla lokutyala kunye nolokugcina amanzi lusetyenziswa kakhulu kuphahla oluthambekileyo, kwaye uphahla lokungenisa umoya lusetyenziswa ngakumbi kuphahla oluthambekileyo.
Ngokuphathelele umgangatho wesakhiwo, kukho amanqanaba aphezulu ophahla olugobileyo.
Inqanaba lolwakhiwo lophahla oluthe tyaba ukusuka kwipleyiti yolwakhiwo lophahla ukuya phezulu yile: ipleyiti yolwakhiwo – umaleko wokuthintela ubushushu – umaleko wokulinganisa – umaleko ongangeni manzi – umaleko wokuzihlukanisa – umaleko okhuselayo
Inqanaba lolwakhiwo lophahla oluthambekileyo luqala kwipleyiti yolwakhiwo lophahla ukuya phezulu: ipleyiti yolwakhiwo – umaleko wokuthintela ubushushu – umaleko wokulinganisa – umaleko ongangeni manzi – umaleko wokubamba iinzipho – umcu osezantsi – umcu wokuxhoma iithayile – ithayile yophahla.

Ngokwezinto ezisetyenziswayo, ukukhethwa kwezinto ezisetyenziswa kuphahla oluthambekileyo kungaphezulu kophahla oluthe tyaba. Ngokuyintloko kungenxa yokuba ngoku kukho iintlobo ezininzi zezinto ezisetyenziswayo zethayile. Kukho iithayile ezincinci eziluhlaza zemveli, iithayile ezicwebezelayo, iithayile ezithe tyaba (iithayile zase-Itali, iithayile zaseJapan), iithayile ze-asphalt njalo njalo. Ke ngoko, kukho indawo eninzi kuyilo lombala kunye nokuma kophahla olugobileyo. Uphahla oluthe tyaba ngokubanzi lwahlulwe lwaba luphahla olufikelelekayo kunye nophahla olungafikelelekiyo. Uphahla olufikelelekayo ngokubanzi lugalelwe ngebhloko yomphezulu ukukhusela umaleko ongangeni manzi ngaphantsi. Uphahla olungafikelelekiyo lugalelwe ngokuthe ngqo ngesamente.

Ngokuphathelele umsebenzi, uphahla oluthe tyaba lungcono kunolophahla oluthambekileyo. Lungasetyenziswa njengethala lokomisa. Lungasetyenziswa njengegadi yophahla kunye nomhlaba. Lungasetyenziswa njengeqonga lokubukela iintaba ezikude kunye nesibhakabhaka esineenkwenkwezi. Ngaphezu koko, umbono wophahla awunakunqotshwa lilanga, eliyindawo engaqhelekanga yangaphandle.

Ngokuphathelele ukumodela koyilo lwefacade, njenge "Fifth Facade", inkululeko yokumodela yophahla olutyibilikayo ingaphezulu kakhulu kuneyophahla oluthe tyaba. Kukho iindlela ezininzi zokuyila, ezinje ngokuqhubeka kophahla olutyibilikayo olwahlukeneyo, indibaniselwano edibeneyo, ukuvulwa kwencochoyi edibeneyo, njl.
