Building in the Northeast costs more than most online calculators account for. Labor markets, site access, and regional material costs vary significantly between counties — what a build costs in Dutchess County is not what it costs in Sullivan County or on a wooded hillside in the Catskills.

The 2x4 Build Cost Calculator is built specifically for the Hudson Valley and Catskills corridor. Select your structure type (cabin, ADU, small home, or barn), square footage, finish level (standard, elevated, or high-spec), and county. The tool outputs an estimated cost range broken out by phase: foundation, envelope, interior finish, and mechanical rough-in.

This is the starting point for every build conversation — grounding the aspiration in real numbers before you spend money on plans, surveys, or site visits. Free to use with no signup required, though creating a free account saves your results and unlocks the rest of the 2x4 toolset.
