Costs To Build New will obviously vary greatly depending on many variables, however there is a basic 'range' you can expect to spend that will help you make decisions on whether or not building new is for you, or working with an existing structure is the way to go.
There are four basic phases that make up the majority of costs in new construction: Plans, Permitting, Site Work, and Construction.
Most architects will charge an hourly rate, and give a basic range of how much time they believe it will take them to draw, engineer, and submit for building permits. A typical range you should expect to pay is somewhere between $160/hr - $200/hr.
Its typically best to have the architect who is drawing the plans also submit for the permits. They will have the most experience in a variety of jurisdictions, and will work with the city to properly fill out and submit the many documents required plan review and building permits. Typically costs for permits will end up running between 3% to 4% of the total cost of the project, and could potentially go up from there depending on several factors like cost to bond, environmental studies/reports, arborists costs, surveying costs, etc.
New construction will always have sitework/site prep that will need to be done prior to construction. Sitework can vary drastically depending on what is already done and what still needs to be done. For instance if you have raw land that is heavily forested then site work will be a greater cost than if the land you own is already cleared, graded, and ready for a house.
Typical construction with fairly contractor grade finishes will cost somewhere between $430 to $500 per square foot and can go up from there. The more custom the home the more the cost. The challenge with keeping costs to a minimum is usually when a homeowner building a new house wants the best of everything, so keeping within budget largely depends on the homeowner.
