Proven Plans.
By purchasing a pre-drawn plan, a building professional can reduce the construction cycle by approximately 60 days. Instead of investing a full three months or more in development of a custom home plan that may be built only a few times, plans may be purchased on an as-needed basis, changes made in 30 days or less and the costs expensed directly to one home instead of spreading it over several builds as part of your overhead.
Cost is another major factor that makes this a logical decision. For a fraction of the cost to generate a custom design the builder has a thorough and complete set of construction documents for a home that is a proven sales winner.
