No! There is more than one concept of prefabrication. The two best known offsite construction systems are the modular and panel systems as we prefer at Laprise. This latter method is not restrictive in the choice of models, modifications or even design it authorizes, unlike the modular. In addition, the principle allows those who wish to get involved to varying degrees in their construction to achieve significant savings and/or do it for the pleasure of building their own house. In short, pre-engineered panel construction is very versatile and combines the advantages of prefabrication with all the flexibility of onsite assembly.
