About Buildzly

Plan smarter. Build better.

Buildzly makes free planning tools for home projects: how much concrete, paint or flooring to buy, what it will cost, and how to measure it right the first time.

Most project mistakes start with a bad number. Too few bags leaves a weak seam in your slab, and too much paint is money left on a shelf. We wanted calculators that show their work, use real manufacturer figures and turn the answer into a shopping list you can take to the store.

Who's behind it

Buildzly is edited by Stephen Morrison, who writes our guides and reviews every calculator against its sources before it goes live.
