The number of options when designing a new home are astonishing. There are hundreds of options in roofing, siding, flooring, windows, doors, sinks, countertops, cabinets, decks, lighting, faucets, etc., each with a different and highly variable price tag. There are thousands of tile options alone. There are also options in framing, plumbing, electrical, heating, cooling, insulation, drywall, and foundations. Many people are misled by unrealistic initial estimates that assume the cheapest of all the options. I recommend assuming $400-600 per square foot for a truly custom built home of our typical quality. Working closely with a knowledgeable designer is the best way to get the results you need while using your budget efficiently.
