孖生兄第Mario及Theo每星期都會去到英國不同的地方，品評一些正出售的豪宅，品評一下室內及室外的家居設計。在首集《大英豪宅》中，他們搜羅了三間外表看似古堡的大宅，但推門入來卻是十分先進、擁有開放式廚房，家居擺設更是高格調，顏色的配搭上也十分鮮明，而其中一間古堡大宅更擁有一個千幾呢的室內泳池、私人保齡球場等設施，簡直是大開眼界。JointheNicolaoubrothersonaquesttofindtheidealhome.Puttingtheirownskillsasanarchitectandaninteriordesignertogooduse,theduopursueaparticulartypeofpropertywhetherit'saplacebythewateroracountrycottage,ahigh-riseapartmentoraGeorgiantownhouse.Huntingdowningtheproperties,theymeetthepeoplewhoarelookingtobuyandsell.Astheshortlistiswhittleddowntothree,howwilltheboysmakethedifficultchoiceofdecidingwhichoneisbest?
