At Nauta Home Designs we evaluate every project individually and offer fixed price quotes so there’s no surprises on what you pay for the permit ready blueprints. The cost of a custom home design varies based on factors such as home type (bungalow vs. two-storey), gross floor area, site conditions, construction type, design complexity, and exterior architecture. Prices range from $5,000 to $50,000, with an average between $5,000 and $10,000 + HST. For example, a 1,000 sq. ft. storey-and-a-half home on a hillside will cost more than a 2,000 sq. ft. country bungalow on flat land.
