This is a great question, especially if you’re someone who grew up in an older prefab in the 1960's. Most post-war prefabs were constructed with an expected lifetime between 10 and 20 years. That’s no longer the case. With proper care and maintenance, a new prefab home can last just as long as standard construction.
Absolutely not. That’s another misconception largely due to the past history of these homes in the UK. While it’s true that post-war prefab homes tended to be unreliable in bad weather, today’s homes will stand up to anything nature can throw at them.
Unfortunately, many people operate under the misconception that a prefab home is nothing more than a glorified caravan. Nothing could be further from the truth. Prefab homes are every bit as sturdy, well-insulated, and permanent as a home built from the ground up. They are for year-round living no matter what the location.
The use of timber structure is entirely up to the builder and his customer. In most cases, prefab homes are made with steel-based sandwich panels in order to keep costs as low as possible. But some home builders offer a timber option for customers who prefer such. Neither one is necessarily better than the other; it’s simply a matter of cost and personal preference.
The assembly of the actual kit can be done in just a matter of days. But site preparation and interior finishing, which are usually the responsibility of the home owner, can add significantly to the build time. On average, most home owners can complete the process — from slab pouring to the final coat of paint — in about 10 days.
Most prefab manufacturers offer several options here. You can purchase a DIY kit you assemble completely on your own, you can pay the builder to take care of the assembly, or you can opt for a combination of both. Obviously, the more you can do on your own, the cheaper the entire package will be.
