🏗️ Building Cost Estimator
Enter floor area, a cost per square foot, the number of stories, and a finish level to get a rough construction budget for early planning.
🔧 Estimate Your Build Cost
What is a Building Cost Estimator?
A building cost estimator gives you a fast, order-of-magnitude construction budget from the factors that move it most: how big the building is, how many stories it has, the local square-foot rate, and the quality of finishes you intend to specify.
It is the right tool for testing whether a project is feasible before you commission drawings. Use it to compare scenarios, then refine with a quantity surveyor or builder.
❓ Frequently Asked Questions
How does the building cost estimator work?
It multiplies your floor area per story by a per-square-foot construction rate and by the number of stories to get a base shell cost, then applies a finish-level multiplier — basic, standard, or premium. The result is an order-of-magnitude budget that captures the two biggest cost drivers: size and finish quality.
What per-square-foot rate should I use?
Use a local figure for your building type, because rates vary widely by region, market conditions, and complexity. Residential construction, commercial fit-out, and custom homes all sit in different bands. If you are unsure, ask a local builder for a current square-foot range and run the estimate at both the low and high ends.
What do the finish levels mean?
Finish level captures the quality of materials and detailing on top of the structural shell. Basic assumes economical, builder-grade choices; standard reflects typical mid-market specification; and premium covers high-end finishes, bespoke joinery, and upgraded systems. The multiplier scales the whole budget to reflect that difference.
Can I rely on this for an actual budget?
Treat it as a starting point for feasibility and comparison, not a contract figure. It excludes land, design fees, permits, site works, and contingency, and real pricing depends on drawings and a tender. It is not a substitute for a quantity surveyor or a builder's detailed estimate.
