Soon after the building regulation act of 1984, construction business faced a leap to comply with the highest standards because of many highlighted deficiencies of traditional construction methods compared to offsite modern methods.
Up to a certain level, U.K. construction companies tended towards offsite construction; however, looking back to the supposed rise of volumetric and hybrid construction methods, limited involvement was observed onwards. Even till the middle years of last decade, while U.K. construction requirements had changed their facets over time, offsite construction is still falling in brevity. In fact, during 1999- 2004, involvement of offsite methods fell somewhere around 2.1% overall and 3.2% among latest constructions (Goodier & Gibb 2005), which raised questions for if volumetric construction methods have not suited U.K. Construction business, or it is the lack of proper skill and awareness to establish volumetric construction participating in U.K. industry majorly.
It must be noticed that hybrid construction is also quite popular among the companies that often find out a separate method for a separate segment of their construction design; and therefore, concerning to the inexactness of calculation, it is not possible to provide a very exact data for how much prefabrication has made its place among the construction companies (Construction Manager 25 June 2004). For example, a constructor who decides to go for an onsite construction can opt for prefabrication of bathrooms and external walls only, because those segments will cost him less while his calculations may indicate him to opt onsite method for rest, or so.
It leads to inquire for what offerings offsite construction methods hold and what restricts them from proposing strong alternatives of traditional onsite construction in U.K. Particularly for U.K., it becomes more bewildering and alarming because prefabrication is very popular among other developed countries that are relying more and more on module
