The general impression on modular homes used to be that they were created with inferior workmanship, but since the industry has evolved over the past few decades, modular homes have become known increasingly not only for their affordability, but also for their superior cross-laminated timber house construction quality. This is due to a few major factors: access to superior quality building materials, construction in a controlled environment, factory-quality inspections, and the need for each module to be so structurally sound that it can survive the trip over highways.
ReplyDeletePermits and approvals take longer than most first-time home builders will expect, but despite the common misconception, it generally isn’t any more or less difficult or time consuming to get permits for a modular home. The first major difference in our solid construction for your new house comes when the actual construction begins. With site-built construction, all site prep and foundation work must be completed before the actual house can be built since the framing for the house must be built on top of a finished foundation
