On time and in budget!

We invested more money then some houses we done into our own proprietary construction software we have developed.   This allows us to get you the most accurate price for your home without guessing.  When you receive a contract to build we generate a list of thousands of parts needed for your job right down to the door stop springs.  Although an accurate estimate might save you tens of thousands on the price your savings starts when you choose to use us.  Each stock plan or custom plan is designed to what we call value engineering. Since certain products come in set sizes or have limits on allowable spans, we design each home to take advantage of all the materials with less in the dumpster.

As additional saving our software allows us to run a tighter schedule and complete your home faster without sacrificing quality.  Your final house price reflects cost for utility services like electrical, water, portable toilet usages and even dumpsters that often get filled at empty job sites with neighbors unwanted items.  When we run job sites with little to no downtime, you save these cost, plus you get to move into your home months sooner.
